Aros/开发者/Zune/自定义类
Zune 自定义类是基于现有 Zune 类新创建的类。自定义类可以对它所基于的类进行改进或修改，从而扩展 Zune。
Zune 自定义类以“.mcc”为后缀识别。
AROS 的 Zune 类（包括提供的自定义类）位于 SYS:Classes/Zune。
Mui 自定义类 (MCC)，其中一些是闭源的。

这是一个定义私有类的示例

一些自定义类随 AROS 提供。其他可以安装到 AROS 中。其他可以从磁盘加载。
在您的应用程序中使用自定义类通常非常简单（就像任何内置类一样）。唯一的前提可能是包含适当的 #include 文件。
例如：如果您一直在使用 Zune 的（内置）“Text”类/对象...
#include <proto/muimaster.h>
#include <libraries/mui.h>
...
TextObject,
MUIA_Text_Contents, "hello world",
...
...您可以完全相同的方式使用自定义类“TextEditor”，只需添加适当的 include 文件并调整属性 (MUIA_...) 以匹配新类
#include <proto/muimaster.h>
#include <libraries/mui.h>
#include <mui/TextEditor_mcc.h>
...
TextEditorObject,
MUIA_TextEditor_Contents, "hello world",
...
另一个例子是“NListview”/“NList”类，它是（内置）“Listview”/“List”类的增强替换。在这种情况下，即使自定义类的属性与原始类的属性也匹配。
当然，这一切都取决于自定义类的构建方式 - 它可能会引入全新的属性或方法。在任何情况下，强烈建议获取自定义类的开发文档，了解其属性和方法。
如果您有一个自定义类，它应该有一个额外的属性，该属性需要通过 Notify 方法触发。您只需将 OM_SET 消息转发到您的超类。
struct TagItem *tags, *tag;
for
(
tags = message->ops_AttrList;
(tag = NextTagItem(&tags));
)
{
switch (tag->ti_Tag)
{
....
}
}
return DoSuperMethodA(CLASS, self, (Msg)message);
如果您希望应用程序能够通过在 progstart 时设置的 Notify 检查属性。那么您需要在类中设置属性，并且应用程序应该根据该通知做出反应。
可以使用 betterstring.mcc 实现回滚缓冲区吗？可以，只需对它进行子类化，并添加优先级高于零的事件处理程序，并对向上/向下箭头键做出反应。我对 API 的想法是使用类似于 MUIM_BetterString_Freeze 的方法，它会将当前缓冲区的内容添加到历史记录中。通常，您会设置一个通知以让 MUIA_String_Acknowledge 触发此方法。此外，应该有一个标记来强制移动到特定缓冲区。
如果您确实创建了缓冲区系统，请让 Freeze 方法验证缓冲区是否已更改，并且只有在更改时才添加 - 没有什么比 unix shell 继续将重复命令添加到历史记录中更令人恼火的了，因此必须向上箭头按 zillion 次才能获得先前的 *不同* 命令...
它功能更强大，因为它支持水平滚动、可点击标题、列重新排列、列重新布局等 - 但大多数人认为它更复杂，速度也不快，而且它有一些缺陷。
像这样创建您的列表
MUIA_NList_Format, "BAR,BAR,BAR,",
这将为您提供一个四列列表，每列之间用垂直线隔开。添加或删除“BAR，”条目以获得所需的列数。如果启用了标题（对于多列列表来说是一个好主意），那么您还应确保您的显示挂钩为每列设置了标题。
为了排序，您必须提供 MUIA_NList_CompareHook（或重载 MUIM_NList_Compare）以获得正确的比较。默认的比较方法仅适用于具有普通字符串指针的单列列表。
如何判断特定条目是否在 NList 的可见部分？您可以使用以下公式计算可见条目：MUIA_NList_Horiz_DeltaFactor、MUIA_NList_Horiz_First 和 MUIA_NList_Horiz_Visible。
如果您使用自定义数据结构
- 需要显示方法/挂钩。
- 如果您使用排序，则需要比较方法/挂钩。
- 构造/析构是可选的，用于临时复制这些结构或您想要的任何内容。
如果缺少构造/析构，NList.mcc 会将您插入的条目直接传递给例如显示/比较/析构。
在 aros 中具有可变数量参数的过程，以及一些该死的宏...这是一个有效且可工作过程，解决了“End”宏的一些问题，以及 DoSuperNew 的实现
IPTR NewObjectAROS( struct IClass *classPtr, STRPTR classID, ULONG tag1, ... )
{
AROS_SLOWSTACKTAGS_PRE(tag1)
retval = (IPTR) NewObject(classPtr, classID, AROS_SLOWSTACKTAGS_ARG(tag1));
AROS_SLOWSTACKTAGS_POST
}
IPTR DoSuperNew(struct IClass *cl, Object *obj, ULONG tag1, ...)
{
AROS_SLOWSTACKTAGS_PRE(tag1)
retval = (IPTR)DoSuperMethod(cl, obj, OM_NEW, AROS_SLOWSTACKTAGS_ARG(tag1));
AROS_SLOWSTACKTAGS_POST
}
IPTR DoSuperNew(Class *cl, Object *obj, Tag tag1, ...)
{
AROS_SLOWSTACKTAGS_PRE(tag1)
retval = DoSuperNewTagList(cl, obj, NULL, AROS_SLOWSTACKTAGS_ARG(tag1));
AROS_SLOWSTACKTAGS_POST
}
或者以更可移植的方式
Object *DoSuperNew(struct IClass *cl, Object *obj, ...)
{
Object *rc;
va_list args;
va_start(args, obj);
rc = (Object *)DoSuperMethod(cl, obj, OM_NEW, va_arg(args, IPTR), NULL);
va_end(args);
return rc;
}
DMethod(my_listview, MUIM_NList_ReplaceSingle, "foo", MUIV_NList_Insert_Active, NOWRAP, ALIGN_LEFT); DoMethod(my_listview, MUIM_NList_Redraw, MUIV_NList_Redraw_Active);
我故意在原型中忽略 __stackparm，因为它目前对 PPC 和 x86-64 没有意义，而且它从未对 i386 和 m68k 有意义。当预处理器在 i386（或任何将所有参数都放在堆栈上的其他体系结构）上扩展宏时。代码将被转换为以下内容
IPTR DoSuperNew(Class *cl, Object *obj, Tag tag1, ...)
{
IPTR retval;
retval = DoSuperNewTagList(cl, obj, NULL, &tag1);
return retval;
}
如果您将函数声明为 static，gcc 的优化器会查看它并决定该函数仅使用其第一个 tag1 参数。像这样的调用
DoSuperNew(cl, o, MUIA_Foo, MUIV_Foo, MUIA_Bar, MUIV_Bar, TAG_MORE, and more)
将转换为：DoSuperNew(cl, o, MUIA_Foo)
实际上会导致未定义的行为。在大多数情况下，FindTagItem() 会浏览堆栈的内容，直到它命中某个地方出现的零长字，因此您几乎不会注意到任何问题。在某些情况下，这会导致内存破坏和非法地址访问。
也许更面向未来的解决方案是使用 va_start() 和 va_end() 宏。在我们要讨论的体系结构上，va_list 只是一个指向当前参数的指针（例如，在我们的示例中，它将是 va_start() 后的 &tag1）。
IPTR DoSuperNew(Class *cl, Object *obj, Tag tag1, ...)
{
IPTR retval;
va_list args;
va_start(args, tag1);
retval = DoSuperNewTagList(cl, obj, NULL, args);
va_end(args);
return retval;
}

NList.mcc
This MCC public custom class is very similar to the MUI's list class. It handles directly most attributes which are handled by Listview in the original couple List/Listview. The NListview exist anyway to provide a complete object with scrollbars, so you should use it as child of NListview. Anyway, you can use NList without NListview if you don't want any built-in scrollbar.
NOTE: NList class will not work with Listview without some conflicts, and NListview class can't use List as child but only NList or a NList subclass.
MUIM_NList_TestPos and MUIM_List_TestPos are similar but use a different struct to store data.
MUIM_List_TestPos works like with a List object.
NOTE: Avoid as possible to do many things in MUIM_Show and MUIM_Hide methods because when an object is in a virtual group, your object will receive them for each one of its moves !!!
Standard tags with NList special values :
MUIA_Background has the same meaning than MUIA_NList_ListBackground but only at init.
MUIA_Font is settable only at init. MUIV_NList_Font, MUIV_NList_Font_Little
and MUIV_NList_Font_Fixed are special values usable for it (settable in prefs)
but standard values are usable too.
MUIA_Frame you can override the defaults frames of the classe by setting it, but it will
be overrided again by defaults if a set(obj,MUIA_NList_Input,bool) is made after.
if MUIA_NList_Input is TRUE then the default is MUIV_Frame_InputList, if FALSE
it's MUIV_Frame_ReadList.
MUIA_ContextMenu
MUIM_ContextMenuBuild
MUIM_ContextMenuChoice
MUIA_NList_Active -- [ISGN], LONG
MUIV_NList_Active_Off
MUIV_NList_Active_Top
MUIV_NList_Active_Bottom
MUIV_NList_Active_Up
MUIV_NList_Active_Down
MUIV_NList_Active_PageUp
MUIV_NList_Active_PageDown
MUIA_NList_ActiveObjectOnClick -- [ISG], BOOL
Default FALSE. If set to TRUE, the NList object will become the MUIA_Window_ActiveObject
of its window when you click on it. In addition, the active selected entries
will switch an inactive color (e.g. grey) in case the NList object isn't currently active.
As soon as the object is active it will then also receive all user keys pressed.
MUIA_NList_AdjustHeight -- [I..], BOOL
Same function as List.mui/MUIA_List_AdjustHeight.
Will adjust the nlist height if the nlist object is in a virtual
group or if MUIA_NList_SourceInsert, MUIA_NList_SourceString,
MUIA_NList_SourceArray or MUIA_List_SourceArray was used.
When the object is in a virtual group, a re-layout of this one
will be forced when the entries number of the NList object change,
so all entries should always be visible.
DEFAULT
FALSE
MUIA_NList_AdjustWidth -- [I..], BOOL
FUNCTION
Same function as List.mui/MUIA_List_AdjustWidth.
Will adjust the nlist width if the nlist object is in a virtual
group or if MUIA_NList_SourceInsert, MUIA_NList_SourceString,
MUIA_NList_SourceArray or MUIA_List_SourceArray was used.
DEFAULT
FALSE
NList.mcc/MUIA_NList_AutoClip
NAME
MUIA_NList_AutoClip -- [ISG], BOOL
FUNCTION
If set to TRUE and the NList object is in read-only (NoInput) mode and
is set to select char-wide rather than by line, the selected content is
immediately copied to the clipboard as soon as it is selected via the
mouse.
MUIA_NList_AutoCopyToClip -- [IS.], BOOL
FUNCTION
If set to TRUE you can copy the selected area to the
clipboard 0 with Amiga-C and Amiga-X (Amiga-X because
i have seen that sometimes Amiga-C is a shortcut !).
(works with both Right-Amiga and Left-Amiga keys)
MUIA_NList_AutoCopyToClip == TRUE also requires that the NList object
is either the window's active object (see MUIA_Window_ActiveObject) or
the attached list object is window's default object (see
MUIA_Window_DefaultObject). Otherwise nothing will ever be copied!
MUIA_NList_AutoVisible -- [ISG], BOOL
FUNCTION
Same function as List.mui/MUIA_List_AutoVisible.
Seting this to TRUE, the NList object will automatically and
always jump to show the active entry.
DEFAULT
FALSE
MUIA_NList_ButtonClick -- [..GN], LONG
FUNCTION
You'll get a notify on it each time the user
clicks one of the buttons made by ESC O[...@<n>] or ESC o[...@<n>].
The returned value is the <n> of the clicked image/object.
(see MUIA_NList_DisplayHook for more).
If you get that value later, it will still be <n> of the latest
image/object clicked that you'll get.
MUIA_NList_ClickColumn -- [..G], LONG
FUNCTION
Same function as Listview.mui/MUIA_Listview_ClickColumn.
MUIA_NList_Columns -- [ISGN], BYTE *
FUNCTION
With this tag you can set/get the visible order of columns (as if changed
by the user). It work for all columns in one time (use MUIM_NList_SetColumnCol
if you want to exchange 2 columns).
The value is a pointer on an BYTE array, each byte is for a column
(in the visible order) and have the value of the display hook col
which have to be displayed in it.
The array must be ended with a -1 value.
MUIA_NList_CompareHook -- [IS.], struct Hook *
FUNCTION
Same function as List.mui/MUIA_List_CompareHook.
MUIA_NList_CompareHook2 -- [IS.], struct Hook *
FUNCTION
Same function as MUIA_NList_CompareHook but A2 will be the object
and A1 a NList_CompareMessage struct pointer.
MUIA_NList_ConstructHook -- [IS.], struct Hook *
FUNCTION
Same function as List.mui/MUIA_List_ConstructHook.
Think to finish lines entries on a \0 , \n and \r.
The list will not display anything which come after
a \n , \r or \0, so finish lines entries on a \0, \r
and \n if you dont want to waste memory.
SPECIAL INPUTS
MUIV_NList_ConstructHook_String
It's a built-in hook that copy a string entry.
(so original string can be trash after)
the MUIV_NList_DestructHook_String
must be set, too if you use it.
MUIA_NList_ConstructHook2 -- [IS.], struct Hook *
FUNCTION
Same function as MUIA_NList_ConstructHook but A2 will be the object
and A1 a NList_ConstructMessage struct pointer.
MUIA_NList_CopyColumnToClipHook -- [IS.], struct Hook *
FUNCTION
This hook will be called while a MUIM_NList_CopyToClip
for each column string. You will get in entry
a string given by your own MUIA_NList_DisplayHook/2, so
you must not use the same buffer for both !
You'll get the entry num in -1 element of the given array,
elements 1 and 2 are the positions of the first selected
char and the last+1.
You must return the pointer of the string to copy to
clipboard in element 0, a the string length in element 1.
The builtin hook skip all ESC chars plus their next char
(and [...] for ESC-P, ESC-I, ESC-O and ESC-o), and add a
tab char between columns.
MUIA_NList_CopyColumnToClipHook2 -- [IS.], struct Hook *
FUNCTION
Same function as MUIA_NList_CopyColumnToClipHook but A2 will be the object
and A1 a NList_CopyColumnToClipMessage struct pointer.
MUIA_NList_CopyEntryToClipHook -- [IS.], struct Hook *
FUNCTION
This work near like MUIA_NList_DisplayHook, except
that it is not called when the NList object want to
display its lines but when it want to copy them
to clipboard (or other). See MUIM_NList_CopyToClip.
You can return only one string pointer (only one
column for copy), as element 0 of the array.
The -1 element is the entry number only when
you don't give a entry pointer to NList_CopyToClip method,
else it's -1.
Elements 1,2,3 and 4 of the given array are first column/pos
and last column/pos which are selected.
Elements 5 and 6 are 2, 1 or 0 when the 1th and 3rd pos are
in the format preparse string, the special entry preparse string
or in the normal string for that entry/columns.
For column, -1 is the first and -2 the last, else it's its number.
This is the number of displayed columns and not the corresponding
entry in the array return by DisplayHook. Anyway, positions are
calculated from strings returned by DisplayHook.
For pos, -1 is left of column and -2 its end. The last pos should
not be included.
You should use MUIA_NList_CopyColumnToClipHook unless you don't
want what is seen in the list to be copied.
MUIA_NList_CopyEntryToClipHook2 -- [IS.], struct Hook *
FUNCTION
Same function as MUIA_NList_CopyEntryToClipHook but A2 will be the object
and A1 a NList_CopyEntryToClipMessage struct pointer.
MUIA_NList_DefaultObjectOnClick -- [ISG], BOOL
FUNCTION
If set to TRUE, the NList object will become the
MUIA_Window_DefaultObject of its window when you
click on it, so the user will be able to control
the list with keys. The MUIA_Window_ActiveObject
will be set to None, unless the current active
object is the NList one itself or if it's the
MUIA_NList_KeepActive one.
There is a special meaning if you use both
DefaultObjectOnClick and MUIA_NList_MakeActive.
(see MUIA_NList_MakeActive)
DEFAULT
TRUE
MUIA_NList_DefClickColumn -- [ISG], LONG
FUNCTION
Same function as Listview.mui/MUIA_Listview_DefClickColumn.
MUIA_NList_DestructHook -- [IS.], struct Hook *
FUNCTION
Same function as List.mui/MUIA_List_DestructHook.
SPECIAL INPUTS
MUIV_NList_DestructHook_String
It's a built-in hook that free the string entry
previously allocated and copied by
the MUIV_NList_ConstructHook_String built-in hook.
MUIA_NList_DestructHook2 -- [IS.], struct Hook *
FUNCTION
Same function as MUIA_NList_DestructHook but A2 will be the object
and A1 a NList_DestructMessage struct pointer.
MUIA_NList_DisplayHook -- [IS.], struct Hook *
FUNCTION
Same function as List.mui/MUIA_List_DisplayHook.
Do not modify the buffers you return in the hook anywhere
else than in the hook when called by NList.
(if you do so you MUST set MUIA_NList_DisplayRecall)
You should return the same thing if it is called another
time with the same inputs!
The hook will be called with a pointer to the
entry to be displayed in A1 and a pointer to
a string array containing as many entries as
your list may have cols in A2.
You must fill this array with the strings that
you want to display.
The array is DISPLAY_ARRAY_MAX*2 large.
In the DISPLAY_ARRAY_MAX+col element you can set a
preparse string for the corresponding col element.
Using it you'll be able to avoid copying the string in
a buffer to add something in the beginning of the col
string.
The display hook also gets the position of the current entry
as additional parameter. It is stored in the longword
preceding the col array (don't forget it's a LONG).
(setting that LONG value to -2 is another way to tell the object
to not consider the return string pointer as valid next time
he will want to use it, and he will recall the hook).
When the hook function will be called to get the title strings,
you'll get NULL in A1, and -1 as position of current entry.
The hook function will be called each time a line (or a part of
it) needs to be drawn (and when NList needs to compute length of
columns contents).
Here are the escape sequence known by the parsing of NList :
(If you use C, ESC b can be written "\033b")
\t Tabulation. Go to the next tab boundary of the col.
tab positions are separated by 8 spaces by default.
ESC - Disable text engine, following chars will be printed
without further parsing.
ESC u Set the soft style to underline.
ESC b Set the soft style to bold.
ESC i Set the soft style to italic.
ESC n Set the soft style back to normal.
ESC <n> Use pen number n (2..9) as front pen. n must be a valid
DrawInfo pen as specified in "intuition/screens.h".
ESC c Center current line. only valid at the beginning.
ESC r Right justify current line. only valid at the beginning.
ESC l Left justify current line. only valid at the beginning.
These ones are new or modified :
ESC j Justify left and right current line, but only at the beginning.
ESC I[<s>] Draw MUI image with specification <s>.
See Image.mui/MUIA_Image_Spec for image spec definition.
ESC O[<p>] (ESC O[<s>|<width>|<height>,<minwidth>])
Draw the MUIM_NList_CreateImage at adress <p>.
(<p> should be an 8 hex digits number).
ESC o[<n>] (ESC o[<s>|<width>|<height>,<minwidth>])
Draw the MUIM_NList_UseImage number <n>. If the <n> UseImage
don't exist or has been set to NULL, no image is drawn.
ESC P[] Use default front pen.
ESC P[<n>] Use pen number <n>. (it's a direct pen number, so you must
make MUI_ObtainPen and MUI_ReleasePen for it yourself,
best to do it is in Setup() and Cleanup() of a subclass).
ESC T Draw horizontal line on top of the entry for the col.
ESC C Draw horizontal line centered in the entry for the col.
ESC B Draw horizontal line on bottom of the entry for the col.
ESC E Draw horizontal line centered in the entry for the col,
but only on the left and right of the line contents.
ESC t , ESC t[<n>] , ESC t[M<n>] , ESC t[I<n>]
Make the ESC C and ESC E horizontal line become thick and filled
with some color :
default is MPEN_FILL.
[<n>] means than <n> is a direct pen color, like for ESC P[<n>]
[M<n>] means that <n> is MUI pen color number (MPEN_xxx ie 0..8)
[I<n>] means that <n> is Intuition dri pen number 0..11 (see
"intuition/screens.h")
ESC t[N], ESC t[N<n>], ESC t[NM<n>], ESC t[NI<n>]
Make the ESC T, ESC C,ESC B, ESC E become a single black line,
or not black when using a <n>, M<n> or I<n> pen color.
('N' is for Not thick ;)
with ESC O[] and ESC o[], you can add [...@<n>] which will make the image/object
act as a relverify button. When this "button" is released NList will notify
MUIA_NList_ButtonClick with the value <n>.
with ESC I[], ESC O[] and ESC o[], you can add [...|<width>] or
[...|<width>|<height>] or [...|<width>|<height>,<minwidth>] or
[...,<minwidth>] where :
<width> will be the width in pixels of the image/object.
-1 means default image width unless <minwidth> is set.
0 means default image width.
<height> will be the height in pixels of the image/object.
-1 means default image height (entry height is max).
0 means entry height.
<minwidth> will be the min width in pixels before the next char/string/image.
when present, default height become entry height and
width become minwidth (if minwdith is bigger than image default
width), unless you set <width> and/or <height>.
<minwidth> <width> and <height> must be a decimal number (%ld).
MUIA_NList_DisplayHook2 -- [IS.], struct Hook *
FUNCTION
Same function as MUIA_NList_DisplayHook but A2 will be the object
and A1 a NList_DisplayMessage struct pointer.
MUIA_NList_DisplayRecall -- [.S.], BOOL
FUNCTION
If for some unusual reason you modify one of the buffer that
your DisplayHook function usually return anywhere else than
in the DisplayHook function when called by the NList object,
you must set it to TRUE, so the object will know it.
MUIA_NList_DoubleClick -- [..GN], LONG
FUNCTION
You'll get a notify on it each time the user double
clicks on an entry in the list, or on the title.
The value is the entry number, which will be -1 when
it's the title.
You'll get a notify on it too when you press the 'return' key
and the NList object is active or default.
If you get() it, you'll get the last click position, which
can be -2 if it was on nothing (ie not entry or title).
For triple clicks and more, use MUIA_NList_MultiClick.
NOTE
Disabled for the title when MUIA_NList_TitleClick is used.
MUIA_NList_DragColOnly -- [ISG], LONG
FUNCTION
When set to a col number (displayhook col number, not the visible
one), only the text of that col for the selected entry will
be dragged instead of the visible part of the entry.
Set it to -1 to come back to standard/default mode when you have
changed it !
MUIA_NList_DragSortable -- [ISG], BOOL
FUNCTION
Same function as List.mui/MUIA_List_DragSortable.
DragType will be MUIV_NList_DragType_Default unless you set it.
No need for you to set MUIA_Dropable or MUIA_Draggable.
DEFAULT
FALSE
MUIA_NList_DragSortInsert -- [..GN], BOOL

immediate drag if non-multiselect mode.
MUIV_NList_DragType_Borders drag on borders and with qualifier.
MUIV_NList_DragType_Qualifier drag only using qualifier.
FUNCTION
Same function as Listview.mui/MUIA_Listview_DragType.
If you want the user to be able to drag items out of
your list, you must set this.
Don't use MUIA_Draggable with NList or NListview.
MUIA_NList_DropMark -- [..G], LONG
FUNCTION
Same function as List.mui/MUIA_List_DropMark.
After a successful drop-operation, this attribute holds
the position where we should insert the new entry(ies).
MUIA_NList_DropType -- [..G], LONG
FUNCTION
Same function as MUIA_NList_DropMark but will return the
current DropMark type instead of the DropMark entry number.
After a successful drop operation, this attribute holds
the type of dropmark which where drawn.
MUIA_NList_Entries -- [..GN], LONG
FUNCTION
Same function as List.mui/MUIA_List_Entries.
MUIA_NList_EntryClick -- [..GN], LONG
FUNCTION
You'll get a notify on it each time the user click
on an entry in the list (on the title, use
MUIA_NList_TitleClick for that).
The value is the entry number.
You'll get a notify on it too when you press the 'return' key
and the NList object is active or default, but only if there
is no notify asked on MUIA_NList_DoubleClick.
If you get() it, you'll get the last click position, which
can be -1 when on title and -2 if it was on nothing.
MUIA_NList_EntryValueDependent -- [ISG], BOOL
FUNCTION
If your display hook return different strings when the
entry num value change for an identical entry pointer
then you should set it.
DEFAULT
FALSE
MUIA_NList_Exports -- [ISG], LONG
FUNCTION
Tell the NList object what parts of it's state will have to
be saved in MUIM_Export method (which is called by the
MUIM_Application_Save method if the object has a ObjectID).
SPECIAL INPUTS
MUIV_NList_Exports_Active save active entry number.
MUIV_NList_Exports_Selected save selected entries numbers.
MUIV_NList_Exports_First save first visible entry number.
MUIV_NList_Exports_ColWidth save widths of columns.
MUIV_NList_Exports_ColOrder save order of columns.
MUIV_NList_Exports_Cols save all about columns (width and order actually).
MUIV_NList_Exports_All
NOTE
MUIV_NList_Exports_Selected can make a very long export (so a big program
.cfg file) if the list has many selected entries. One long int
(ie four bytes) is required for each selected entry...
Active and First are always exported by the MUIM_Export method,
having MUIV_NList_Exports_Active and MUIV_NList_Exports_First set or not.
DEFAULT
(MUIV_NList_Exports_Active | MUIV_NList_Exports_First | MUIV_NList_Exports_Cols)
MUIA_NList_First -- [ISGN], LONG
SPECIAL INPUTS

SPECIAL INPUTS
MUIV_NList_ForcePen_On
MUIV_NList_ForcePen_Off
MUIV_NList_ForcePen_Default
FUNCTION
Set the ForcePen mode, when on it force the 'selected pen' color
in all the selected area. Else the color is forced only at the
beginning of the area and can be changed by text escape sequences.
The default is set by the user in the pref .mcp class.
Getting in will give its current value.
MUIA_NList_Format -- [ISG], STRPTR
FUNCTION
NList is able to handle multi column lists. To define
how many columns should be displayed and how they
should be formatted, you specify a format string.
This format string must contain one entry for each column
you want to see. Entries are separated by commas, one
entry is parsed via dos.library/ReadArgs().
The template for a single entry looks like this:
DELTA=D/N,PREPARSE=P/K,COL=C/N,BAR/S,TBAR/S,NOBAR=NB/S,
SIMPLEBAR=SBAR/S,NOTITLEBUTTON=NOTB/S,
WEIGHT=W/N,MINWIDTH=MIW/N,MAXWIDTH=MAW/N,
COLWIDTH=CW/N,MINCOLWIDTH=MICW/N,MAXCOLWIDTH=MACW/N,
PIXWIDTH=PW/N,MINPIXWIDTH=MIPW/N,MAXPIXWIDTH=MAPW/N,
PARTCOLSUBST=PCS/K
The first are similar to MUIA_List_Format ones :
DELTA
Space in pixel between this column and the next.
the last displayed column ignores this setting.
Defaults to 4.
PREPARSE
A preparse string for this column.
COL
This value adjusts the col number of the current column.
Defaults to current column number (0,1,...)
You can't use identical COL values for 2 or more columns.
BAR
Will draw a vertical bar between this and the next column.
WEIGHT
The weight of the column. As for MUI's group.
MINWIDTH
Minimum percentage of the list width for the current column.
MAXWIDTH
Maximum percentage of the list width for the current column.
TBAR
Will draw a vertical bar between this and the next column
but only in the title (ignored if BAR is set).
THIS IS A DEFAULT !
NOBAR
Don't draw a vertical bar between this and the next column at all.
SIMPLEBAR
Make te vertical bar a simple black one.
NOTITLEBUTTON
Will prevent the title of the column to act as a reverify
button when you set MUIA_NList_TitleClick (or make a notify
on it).
COLWIDTH
Wanted number of chars for the current column.
You will get as PIXWIDTH with number*font_with.
Possibly more than number chars will fit in the
column if you use proportional font, anyway you
are sure than number non-italic chars will fit.
MINCOLWIDTH
Minimum number of chars for the current column.
MAXCOLWIDTH
Maximum number of chars for the current column.
PIXWIDTH
Wanted number of chars for the current column.
MINPIXWIDTH
Minimum number of chars for the current column.
MAXPIXWIDTH
Maximum number of chars for the current column.
PARTCOLSUBST
If the partial column feature is turned on by the
user (in his configuration) and the application
developer has specified this option for a particular
column, then a "..." text is displayed at the
defined position if not all text fits into the
column rather than showing a dotted vertical line
at the end of the column. Possible values for
this option are:
DISABLED
explicitly disables this feature for this
column
LEFT
put "..." on the left side and strip text
left aligned.
CENTER
put "..." at the center of the column and
strip text on both sides around it.
RIGHT
put "..." on the right side and strip text
right aligned.
Note: You will have as many columns in your list as
entries in the format string (i.e. number of
commas + 1). Empty entries, e.g. with a format
string of ",,,," are perfectly ok.
MINPIXWIDTH, MAXPIXWIDTH, MINCOLWIDTH, MAXCOLWIDTH,
MINWIDTH and MAXWIDTH will not be used if PIXWIDTH,
or COLWIDTH is used.
Only one of PIXWIDTH, COLWIDTH and WEIGHT will be
used, the first find in this order.
Biggest of MINPIXWIDTH, MINCOLWIDTH and MINWIDTH.
Smallest of MAXPIXWIDTH, MAXCOLWIDTH and MAXWIDTH.
If the min is bigger than the max the min will be used.
Use PIX ones only for columns with images,
and COL ones to be sure to get as many
chars as wanted.
All chars/images will be drawn for the last column
always, specify some width for it anyway,
as it will be used for centered and right aligned texts !
Default values : WEIGHT=-1, MINWIDTH=5, MAXWIDTH=10000.
Use MINWIDTH=0 if you don't use PIXWIDTH or COLWIDTH and
don't want any min value.
To get WEIGHT values as a percentage of the list
width, choose them to have their total being 100.
WEIGHT = -1 means that you want the column to have
the width of the largest entry's column contents.
MINWIDTH = -1 has the same meaning as for WEIGHT but for
the min value.
Default will be 100 for the last column, set it to -1 or
-2 if you want to force it when more than one column, and
to -2 to force it when only one column.
Be aware that it can take long time to do that when there
are many entries since this need a call to the dislpayhook,
parse and find real length of all entries.
Anyway using such stuff for one or more columns has the
same overhead.
The default list format is an empty string (""), this
means an unformatted, single-column list.
NOTE
MUIA_NList_Format will not try to see if the new
format is similar to previous one. It means that all
column width will be re-computed (and all entries parsed
if WEIGHT or MINWIDTH is -1), same for wrapping
which will be recomputed for all entries.
So, it's better to do it before inserting entries
in order to do both.
To clear, insert and set the format, the
best is to set the format after the clear (fastest, no
entry to parse) and before the insert.
BUGS (FEATURE)
Currently there is a maximum of 64 columns for a list.
MUIA_NList_Horiz_DeltaFactor -- [..GN], LONG
FUNCTION
Used for NListview. You can make a notification on it
if you want to attach your own horizontal scrollbar
and set the increment value of scrollbar's arrows :

MUIA_NList_IgnoreSpecialChars -- [ISG], const char *
FUNCTION
Used to let NList ignore a list of user definable characters during
string parsing. Some Greek fonts need the 0xA0 character to display
an Alpha characters. In this case the string "\xa0" should be supplied
to make NList ignore this character and not treat 0xA0 as a "non
breaking space".
This string will *NOT* be copied by NList and must remain valid as long
as the object exists!
DEFAULT
NULL
MUIA_NList_Imports -- [ISG], LONG
FUNCTION
Tell the NList object what parts of it's state must be loaded
(and used) in MUIM_Import method (which is called by the
MUIM_Application_Load method if the object has a ObjectID).

MUIV_NList_Imports_ColOrder load previous order of columns (and set it).
MUIV_NList_Imports_Cols load all about columns (width and order actually).
MUIV_NList_Imports_All
DEFAULT
(MUIV_NList_Imports_Active | MUIV_NList_Imports_First | MUIV_NList_Imports_Cols)
MUIA_NList_Input -- [ISG], BOOL
FUNCTION
Same function as NListview.mcc/MUIA_Listview_Input.
DEFAULT
TRUE
MUIA_NList_InsertPosition -- [..GN], LONG
FUNCTION
Same function as List.mui/MUIA_List_InsertPosition.
MUIA_NList_KeepActive -- [.S.], Obj *
FUNCTION
Useful when MUIA_NList_DefaultObjectOnClick to not
have the specified object deactivated.
A NListview object set it to it's NList child at
creation time, so you should not have to use that tag.
MUIA_NList_KeyUpFocus -- [ISG], Object *
FUNCTION
Allows to specify an object that will be set as the new
window's active object in case the user pressed the UP cursor key
and the NList object itself doesn't have anything further to
scroll up.
MUIA_NList_KeyDownFocus -- [ISG], Object *
FUNCTION
Allows to specify an object that will be set as the new
window's active object in case the user pressed the DOWN cursor key
and the NList object itself doesn't have anything further to
scroll down.
MUIA_NList_KeyLeftFocus -- [ISG], Object *
FUNCTION
Allows to specify an object that will be set as the new
window's active object in case the user pressed the LEFT cursor key
and the NList object itself doesn't have anything further to
scroll to the left.
MUIA_NList_KeyRightFocus -- [ISG], Object *
FUNCTION
Allows to specify a specific object that will be set as the new
window's active object in case the user pressed the RIGHT cursor key
and the NList object itself doesn't have anything further to
scroll to the right.
MUIA_NList_LineHeight -- [..GN], LONG
FUNCTION
Get the current line height.
MUIA_NList_MakeActive -- [.S.], Obj *
FUNCTION
Use it if you want an object to be activated when you click
in the list object.
To be able to control the list with key,
use MUIA_NList_DefaultObjectOnClick instead.
Using both MUIA_NList_MakeActive and
MUIA_NList_DefaultObjectOnClick then the specified object
will be activated only if there is already an active one.
The only object which should be set should be the NListview
parent object of the current NList one.
MUIA_NList_MinColSortable -- [ISG], LONG
FUNCTION
Sets the number of the first visible column which
can be sorted, ie exchanged with some other one.
Default is 1, making the leftmost (0) column not sortable.
Just set it to a big number (100 for example) to forbid
the columns sorting.
MUIA_NList_MinLineHeight -- [IS.], LONG
FUNCTION
Same function as List.mui/MUIA_List_MinLineHeight.
Sets the minimum line height for lists in pixels.
If <= 0 then it's absolute value will replace the
'Leading' value of prefs which is added to the
font height.
It seems that the original MUIA_List_MinLineHeight uses
its positive value as a 'leading' one, which is not
logical when I read its doc (!), so I do the
change internally to get it works like with list...
MUIA_NList_MultiClick -- [..GN], LONG
FUNCTION
You'll get a notification on it each time the user
multiclicks more than twice on an entry in the
list, or on the title. You'll get the number of
the click (3, 4, 5...) for each. Note that you'll
not get MUIA_NList_MultiClick for a double click;
you must use MUIA_NList_DoubleClick for that.
The time between each click must be less or equal
to the double click time set in Amiga Input prefs.
To know on which entry the multiclick was made
getting MUIA_NList_DoubleClick value.
So you can make a notification on it.
NOTE
Disabled for the title when MUIA_NList_TitleClick is used.
MUIA_NList_MultiClickAlone -- [..GN], LONG
FUNCTION
You'll get a notification only for the final multiclick number,
so if there are three clicks there will be only one multiclickalone
notified, a little (max time between two clicks) after the third one.
It is the major change with classic MUIA_NList_DoubleClick and
MUIA_NList_MultiClick which do the notify for all clicks.
The drawback is the unavoidable delay between the last click
and the notification.
You can know on which entry the multiclickalone was made
getting MUIA_NList_DoubleClick value.
A notification can be made on it.
MUIA_NList_MultiSelect -- (V7 ) [I..], LONG

SBobj, 3, MUIM_NoNotifySet,MUIA_Prop_Visible,MUIV_TriggerValue);
MUIA_NList_Quiet -- [.S.], BOOL
FUNCTION
Same function as List.mui/MUIA_List_Quiet.
Consider using it when inserting or removing several entries
one-by-one, it will go much faster.
In all cases, all changes which can be done later are delayed.
Quiet_Full mean that no notification caused by changes in the list will
be made, while Quiet_Visual will do them (but delayed to after
the Quiet_None).
SPECIAL INPUTS
MUIV_NList_Quiet_None same as FALSE.
MUIV_NList_Quiet_Full all values but FALSE and MUIV_NList_Quiet_Visual (-2).
MUIV_NList_Quiet_Visual
MUIA_NList_SelectChange -- [...N], BOOL

EXAMPLES
See NList-Demo program.
MUIA_NList_SortType2 -- [ISGN], LONG
FUNCTION
This value will be set in the NList_CompareMessage struct
of MUIA_NList_CompareHook2 hook function.
It is set by MUIM_NList_Sort3 method, too.
EXAMPLES
See NList-Demo program.
MUIA_NList_SourceArray -- [I..], APTR
FUNCTION
Same function as List.mui/MUIA_List_SourceArray.
MUIA_NList_SourceInsert -- [I..], struct MUIP_NList_InsertWrap *
FUNCTION
Same as DoMethod(obj,MUIM_NList_InsertWrap,...)
with ... same as the contents of the passed struct,
but at init.
MUIA_NList_SourceString -- [I..], char *
FUNCTION
Same as
DoMethod(obj,MUIM_List_Insert,string,-2,MUIV_NList_Insert_Bottom)
but at init.
MUIA_NList_TabSize -- [ISG], ULONG
FUNCTION
Same function as Floattext.mui/MUIA_Floattext_TabSize.
Set how many spaces is the tabulation.
Default is 8.
MUIA_NList_Title -- [ISG], char *
FUNCTION
Same function as List.mui/MUIA_List_Title.
The title will be redrawn each time you set it.
When you use a display hook, its value is used as a BOOL/LONG
which can have any value (just not NULL if you want to see it).
The value returned by get() will be the same than the last one
given in the set() or at init.
MUIA_NList_TitleClick -- [ISGN], LONG
FUNCTION
A notification is received each time the user
clicks one the title (only if on a column, so not on the
vertical bar column separator which is used to modify the
column-width with mouse).
The returned value is the col number (display hook col number).
If you get that value later, it will still be the latest
*title* click col received.
If a notification on that tag is requested, or if you set it (with any
value), the title will act as if each of its column titles were
separated buttons, notifying that tag when they are released.
Using MUIA_NList_TitleSeparator and BAR or TBAR for each
column in the MUIA_NList_Format string will improve the
(released) look for those title "buttons".
There are no shortkeys for these custom buttons and never will be,
so find another way to access the related material.
Don't ask for customized frames for them : they are not real
MUI and separated buttons but directly handled by NList, and I
consider it already sufficient.
NOTE
When you use MUIA_NList_TitleClick, you will not receive
MUIA_NList_DoubleClick and MUIA_NList_MultiClick when clicking
on the title any more.
EXAMPLES
See NList-Demo program.
MUIA_NList_TitleClick2 -- [ISGN], LONG

title and the first visible entry (only when some title
is visible).
DEFAULT
TRUE
MUIA_NList_TypeSelect -- [IS.], LONG
SPECIAL INPUTS
MUIV_NList_TypeSelect_Line
MUIV_NList_TypeSelect_Char
FUNCTION
This tag offers a choice between the classic
list selection by line and using a char precision
selection.
This should be used only for textviewer-like stuff,
and never for standard lists.
Anyway it's the only way to make direct copytoclip
of a part of a line...
Default is MUIV_NList_TypeSelect_Line of course.
MUIA_NList_Visible -- [..G], LONG
FUNCTION
Same function as List.mui/MUIA_List_Visible.
MUIA_NList_TitleBackground -- [ISG], LONG

MUIA_NList_CursorBackground -- [ISG], LONG
MUIA_NList_UnselCurBackground -- [ISG], LONG
FUNCTION
All backgrounds of NList can be set with these attributes,
look at Area.mui/MUIA_Background and Image.mui/MUIA_Image_Spec
to see what kind of value can be used.
Anyway, the defaults can be set with prefs and so do
not set it yourself.
MUIA_NList_TitlePen -- [ISG], LONG
MUIA_NList_ListPen -- [ISG], LONG

value must be of the type Pendisplay.mui/MUIA_Pendisplay_Spec.
Look at Pendisplay.mui, Area.mui/MUIA_Background and
Image.mui/MUIA_Image_Spec.
Anyway, you can set the defaults with prefs and should
not set it yourself.
MUIM_NList_Clear --
SYNOPSIS
DoMethod(obj,MUIM_NList_Clear,);
FUNCTION
Same function as List.mui/MUIM_List_Clear.
MUIM_NList_ColWidth --
SYNOPSIS
DoMethod(obj,MUIM_NList_ColWidth,LONG col,LONG width);
FUNCTION
Set a width for a col as if changed by the user with mouse, or
reset it to its default size.
Permit to get the user width of a col too.
INPUTS
col number of the col (numbered as in display hook).
special value :
MUIV_NList_ColWidth_All will set it for all columns.
width width to set (four is the minimum acceptable width).
special values :
MUIV_NList_ColWidth_Default reset to default.
MUIV_NList_ColWidth_Get set nothing, only return current.
RESULT
When a col is specified (ie not MUIV_NList_ColWidth_All), the current
*user* width of the col will be returned :
o -1 mean that the col has its default width, ie not set by the user
or with this method.
o 0 mean that the specified col is not valid.
When MUIV_NList_ColWidth_All you'll get always 0.
MUIM_NList_ColToColumn --
SYNOPSIS
DoMethod(obj,MUIM_NList_ColToColumn,LONG col);
FUNCTION
converts display hook col number to visible column number.
INPUTS
col number of the col (numbered as in display hook).
RESULT
column number, -1 if no column use that col number.
MUIM_NList_ColumnToCol --
SYNOPSIS
DoMethod(obj,MUIM_NList_ColumnToCol,LONG column);
FUNCTION
converts visible column number to display hook col number.
INPUTS
column number of the column (visible).
RESULT
col number, -1 if the column is not valid.
MUIM_NList_Compare --
SYNOPSIS
DoMethod(obj,MUIM_NList_Compare,APTR entry1,APTR entry2,
ULONG sort_type1,ULONG sort_type2);
FUNCTION
This method is called ONLY by NList.mcc when the application
needs to compare two list entries, for example when MUIM_NList_Sort,
MUIM_NList_Sort2, MUIM_NList_Sort3 are called. So, this method is
only useful within NList.mcc subclass, function method should
looks like normal MUIA_NList_CompareHook or MUIA_NList_CompareHook2
hook function. If your subclass will not override this method
NList.mcc implementation will be used and it will call
MUIA_NList_CompareHook or MUIA_NList_CompareHook2 hook in that case.
When you are overriding this method you probably would like to override
MUIM_NList_Construct, MUIM_NList_Destruct and MUIM_NList_Display method
as well.
INPUTS
entry1 - First entry to compare.
entry2 - Second entry to compare.
sort_type1 - Sort type 1.
sort_type2 - Sort type 2.
RESULTS
If entry1 > entry2 1, if entry1 == entry2 0 and if entry1 <
entry2 -1. i.e. the same as MUIA_NList_Compare,
MUIA_NList_CompareHook2 or strcmp() alike functions.
NOTE
Do not call it by yourself! Method parameters
structure might grow in the future! Be warned.
Internal implementation of this method can use internal or passed
arguments, so please do not cheat and if you do not override it,
pass the original arguments to super class.
MUIM_NList_Construct --
SYNOPSIS
DoMethod(obj,MUIM_NList_Construct,APTR entry,APTR pool);
FUNCTION
This method is called ONLY by NList.mcc when application is
creating new entry f.e. when MUIM_NList_Insert,
MUIM_NList_InsertSingle or MUIM_NList_Replace is called. So, this
method is only useful within NList.mcc subclass, function method
should looks like normal MUIA_NList_ConstructHook or
MUIA_NList_ConstructHook2 hook function. If your subclass will
not override this method NList.mcc implementation will be used,
and it'll call MUIA_NList_ContructHook or
MUIA_NList_ConstructHook2 hook in that case.
When, overriding this method, it is probably to override
MUIM_NList_Destruct, MUIM_NList_Compare and MUIM_NList_Display
methods as well.
INPUTS
entry - original entry pointer passed to f.e. MUIM_NList_Insert
method. Equivalent of A1 register of
MUIA_NList_ConstructHook.
pool - pool header pointer. Equivalent of A2 register
of MUIA_NList_ConstructHook.
RESULT
New entry, similar as returned by one of construct hooks.
NOTE
Do not call it by yourself! Method parameters
structure might grow in the future! Be warned.
Internal implementation of this method can use internal or passed
arguments, so please do not cheat and if you are not
overriding it, pass the original arguments to super class.
MUIM_NList_ContextMenuBuild --
SYNOPSIS
DoMethod(obj,MUIM_NList_ContextMenuBuild, LONG mx, LONG my, LONG pos,
LONG column, LONG flags,LONG ontop);
FUNCTION
Give possibilities to use MUIM_ContextMenuBuild builtin in NList
and a custom context menu for a NList subclass.
Here is how NList MUIM_ContextMenuBuild work :
If MUIA_ContextMenu is NULL, NULL is returned (no menu).
If MUIA_ContextMenu is none of special values, the supermethod is called.
If MUIA_ContextMenu is MUIV_NList_ContextMenu_Never, MUIA_ContextMenu is
set to NULL and NULL is returned.
Else (it's a special value) MUIM_NList_ContextMenuBuild is called :
If MUIM_NList_ContextMenuBuild return -1, NULL will be returned (no menu).
If MUIM_NList_ContextMenuBuild return NULL, NList will return its own
context menu, depending on prefs (it's the default case).
If MUIM_NList_ContextMenuBuild return an menu object, NList will
enable/disable its own menu entries in the menu if it found some,
then return thqt object.
2 special menuitems are recognised by NList, and are found by :
DoMethod(MenuObj,MUIM_FindUData,MUIV_NList_Menu_Default_This)
and
DoMethod(MenuObj,MUIM_FindUData,MUIV_NList_Menu_Default_All)
MUIA_ContextMenu special values are actually used :
MUIV_NList_ContextMenu_Default replaced by one of following.
MUIV_NList_ContextMenu_TopOnly only on title/top of list.
MUIV_NList_ContextMenu_Always always.
MUIV_NList_ContextMenu_Never never, replaced by NULL after.
when using MUIV_NList_ContextMenu_TopOnly NList will set MUIA_ContextMenu
NULL/non-NULL when the mouse move, which should permit to have
the window menu avaible when the contents menu is not visible.
Anyway actually (MUI 3.8) MUI has a bug/feature which make the
MUIA_ContextMenu being looked at only when the mouse *enter*
within the object bounds. MUIV_NList_ContextMenu_TopOnly stuff
will be nicer when that MUI problem is fixed...
Of course if you want NList to do what has to be done when a menu item
has been selected, your MUIM_ContextMenuChoice should call the supermethod.
INPUTS (for MUIM_NList_ContextMenuBuild)
mx current mouse x.
my current mouse y.
pos entry number returned by NList_TestPos.
column column returned by NList_TestPos.
flags flags returned by NList_TestPos.
ontop TRUE if mouse is on title/top of the list.
RESULT
NULL, -1 or a menustrip object.
EXAMPLES
To make a ContextMenu but have the NList one appear when the
mouse in on title/top, just set MUIA_ContextMenu,MUIV_NList_ContextMenu_Always
and make MUIM_NList_ContextMenuBuild return NULL when ontop in TRUE (else
return your menustrip object). Call MUIM_ContextMenuChoice supermethod too.
To make your own context menu which have the same menuitems as ones
in NList context menu, set MUIA_ContextMenu,MUIV_NList_ContextMenu_Always
and make MUIM_NList_ContextMenuBuild return always your menustrip object.
Make 4 menuitems in your menustrip object which will be like these :
{ NM_ITEM , "Default Width: this" , 0 ,0 ,0 ,(APTR) MUIV_NList_Menu_DefWidth_This },
{ NM_ITEM , "Default Width: all" , 0 ,0 ,0 ,(APTR) MUIV_NList_Menu_DefWidth_All },
{ NM_ITEM , "Default Order: this" , 0 ,0 ,0 ,(APTR) MUIV_NList_Menu_DefOrder_This },
{ NM_ITEM , "Default Order: all" , 0 ,0 ,0 ,(APTR) MUIV_NList_Menu_DefOrder_All },
They will be automatically enabled/disabled as needed by NList :)
Call MUIM_ContextMenuChoice supermethod too.
MUIM_NList_CopyTo --
SYNOPSIS
DoMethod(obj,MUIM_NList_CopyTo, LONG pos, char *filename,
APTR *result, APTR *entries);
FUNCTION
Do a copy to clipboard from some list entries or strings.
INPUTS
pos entry number to be copied.
if MUIA_NList_CopyToClipHook is specified, it's what
it will return which will be copied instead of just
using the entry pointer as a string pointer.
special values :
MUIV_NList_CopyTo_Active copy list active entry
MUIV_NList_CopyTo_Selected copy list selected entries
MUIV_NList_CopyTo_All copy all list entries
MUIV_NList_CopyTo_Entries copy specified entries
MUIV_NList_CopyTo_Entry copy specified entry
a "\n" will be inserted after each entry contents.
filename name of the file to copy to. If NULL then the copy will be
done to a string (strptr).
result LONG pointer which fill be filled with MUIV_NLCT_Success if
no error occured while opening and writing in the file, else
it will be filled with MUIV_NLCT_OpenErr, MUIV_NLCT_WriteErr
or MUIV_NLCT_Failed (failed somewhere when making copy data).
if filename is NULL, result will be filled with a string pointer
to a string allocated by AllocVec(). Data will have been copied
in that string. You will have to free that string pointer yourself,
with a FreeVec(). If the returned string pointer is NULL then
the copy failed.
entries pointer to some entry, string, entries array or string array.
Its use depend on the pos value :
if MUIV_NList_CopyTo_Entry then it's an entry pointer.
if MUIV_NList_CopyTo_Entries then it's an entry pointer
array NULL terminated.
else : not used, set to NULL.
EXAMPLES
LONG result = 0;
DoMethod(obj,MUIM_NList_CopyTo, 5, "RAM:test.txt", &result, NULL, NULL);
will copy the 5th entry to file RAM:test.txt, using
MUIA_NList_CopyToClipHook if set.
LONG result = 0;
DoMethod(obj,MUIM_NList_CopyTo, MUIV_NList_CopyToClip_Selected,
"PRT:", &result, NULL, NULL);
will copy all selected entries to printer, using
MUIA_NList_CopyToClipHook for each if set.
char *strptr = NULL;
DoMethod(obj,MUIM_NList_CopyTo, MUIV_NList_CopyTo_All,
NULL, &strptr, NULL, NULL);
will copy all list entries to the string returned in strptr.
you must make a FreeVec(strptr) by yourself after.
MUIM_NList_CopyToClip --
SYNOPSIS
DoMethod(obj,MUIM_NList_CopyToClip, LONG pos, ULONG clipnum,
APTR *entries, struct Hook *hook);
FUNCTION
Do a copy to clipboard from some list entries or strings.
INPUTS
pos entry number to be copied.
if MUIA_NList_CopyToClipHook is specified, it's what
it will return which will be copied instead of just
using the entry pointer as a string pointer.
special values :
MUIV_NList_CopyToClip_Active copy list active entry
MUIV_NList_CopyToClip_Selected copy list selected entries
MUIV_NList_CopyToClip_All copy all list entries
MUIV_NList_CopyToClip_Entries copy specified entries
MUIV_NList_CopyToClip_Entry copy specified entry
MUIV_NList_CopyToClip_Strings copy specified strings using hook
MUIV_NList_CopyToClip_String copy specified string using hook
a "\n" will be insert after each entry contents, for all but
MUIV_NList_CopyToClip_Strings and MUIV_NList_CopyToClip_String.
clipnum clipboard number to copy to.
entries pointer to some entry, string, entries array or string array.
Its use depend on the pos value :
if MUIV_NList_CopyToClip_Entry then it's an entry pointer.
if MUIV_NList_CopyToClip_Entries then it's an entry pointer
array NULL terminated.
if MUIV_NList_CopyToClip_String then it's a string pointer.
if MUIV_NList_CopyToClip_Strings then it's an string pointer
array NULL terminated.
else : not used, set to NULL.
hook hook function which will be used (if not NULL) for
MUIV_NList_CopyToClip_Strings and
MUIV_NList_CopyToClip_String
instead of MUIA_NList_CopyToClipHook
Should be NULL most of time.
EXAMPLES
DoMethod(obj,MUIM_NList_CopyToClip, 5, 0, NULL, NULL);
will copy the 5th entry to clipboard 0, using
MUIA_NList_CopyToClipHook if set.
DoMethod(obj,MUIM_NList_CopyToClip, MUIV_NList_CopyToClip_Selected,
0, NULL, NULL);
will copy all selected entries to clipboard 0, using
MUIA_NList_CopyToClipHook for each if set.
DoMethod(obj,MUIM_NList_CopyToClip, MUIV_NList_CopyToClip_String,
0, "my string", NULL);
will copy "my string" to clipboard 0.
NOTE
MUIV_NList_CopyToClip_Strings and MUIV_NList_CopyToClip_String
are here to permit simple text copy to clipboard for non nlist
object related stuff (anyway a NList object must be here to use
them...). They can use their own hook instead of the nlist's if
non NULL, anyway look at MUIA_NList_CopyToClipHook to see how
this hook will be used.
MUIM_NList_CreateImage --
SYNOPSIS
DoMethod(obj,MUIM_NList_CreateImage,Object *imgobj, ULONG flags);
FUNCTION
Same function as List.mui/MUIM_List_CreateImage.
Any transparent color in the source Bitmap/Bodychunk
object will work (except if flags is ~0L).
MUIM_NList_CreateImage must be used in Setup() or after
and MUIM_NList_DeleteImage, in Cleanup() or before,
because the mri of the NList object must be valid.
Setup() and Cleanup() are the best because MUI_ObtainPen()
and MUI_ReleasePen() are used, and then pens will be
released while iconification and will be re-obtained
if the screen change.
Take a look at MUIM_NList_UseImage which is far easier to
use.
Standard flags value is 0.
If flags is ~0L then FillArea will not be set to FALSE on the object
(for any other value, FillArea is set to FALSE)
If flags is ~0L for a Bitmap/Bodychunk then it will be really the
given object which will be drawn, as for non Bitmap/Bodychunk objects.
The imgobj can (nearly) be any object, but take care of that :
- the object should not test and use user inputs, the object
should just be able to draw itself within the _left(obj),
_top(obj), _width(obj) and height(obj) it will have when its
Draw method is called.
- the object class MUST NOT be Group or subclass of it.
- the given imgobj must not be attached to any group object
anywhere else, because a ADDMEMBER will be done with it.
- Each imgobj can be used with one and only one NList object.
- you can use the return pointer with ESC O[<ptr>] and ESC o[<num>].
- the object will receive two tags just before its Draw method will
be called : set(imgobj,MUIA_NLIMG_EntryCurrent,current_entry_number) and
set(imgobj,MUIA_NLIMG_EntryHeight,height_of_each_entry_of_the_list)
which are usefull in some case to draw things (see demo example).
- a new stuff is to use it with ESC O[<ptr>;<tag>;<value>], in that case
a set(imgobj,tag,value) will be done just before drawing it, so
you can make an object which will draw different things when that tag
value is changed. Setting this tag MUST NOT cause the item to be redrawn!
<tag> and <value> must both be in hexadecimal (%lx).
- If you use ;<tag>;<value> in one ESC sequence for an imgobj, you should
use it everywhere you use that imgobj because there is no default for it.
- The imgobj height will always be set to the entries height.
- The mindefheight of imgobj will become the min height for entries.
- Think it's still a new testing stuff...
Note:
Previously the object was disposed by NList at its end, actually a call
to MUIM_NList_DeleteImage will REMMEMBER it, and so you have to dispose
of it yourself afterwards !
Look the demo program to see a way to use it...
RESULT
The result you get is a struct BitMapImage pointer which
will exist between the MUIM_NList_CreateImage and
MUIM_NList_DeleteImage, with a valid bitmap, width and
height for the current screen.
If you use it for a non Bitmap/Bodychunk object (or with flags
set to ~0L) then the mask and imgbmp fields of the returned
struct BitMapImage are not valid, and obtainpens is a pointer to
the object.
The only thing you should do with it is to include it in
\33O[%08lx]. The result may be NULL in which case NList
was unable to create the image, but the \33O[] combination
simply draws nothing when receiving a NULL.
ATTENTION:
The returned pointer doesn't give the same structure than
MUIM_List_CreateImage (in standard List class) would do :
both are not compatible at all !
MUIM_NList_DeleteImage --
SYNOPSIS
DoMethod(obj,MUIM_NList_DeleteImage,APTR listimg);
FUNCTION
Same function as List.mui/MUIM_List_DeleteImage.
Delete the image pointer returned from MUIM_NList_CreateImage.
Read explains in MUIM_NList_CreateImage.
MUIM_NList_Destruct --
SYNOPSIS
DoMethod(obj,MUIM_NList_Destruct,APTR entry,APTR pool);
FUNCTION
This method is called ONLY by NList.mcc when application is
deleting entry f.e. when MUIM_NList_Remove or MUIM_NList_Replace
are called. So, this method is only useful within NList.mcc
subclass, function method should looks like normal
MUIA_NList_DestructHook or MUIA_NList_DestructHook2 hook
function. If your subclass will not override this method
NList.mcc implementation will be used, and it'll call
MUIA_NList_DestructHook or MUIA_NList_DestructHook2 hook in that
case.
When you are overriding this method you must override
MUIM_NList_Construct and probably MUIM_NList_Compare and
MUIM_NList_Display method as well.
INPUTS
entry - entry pointer returned by MUIM_NList_Construct method.
pool - pool header pointer.
RESULT
Currently undefined. When overriding it completely, please return
0, if not, use the value returned by super class!
NOTE
Do not call it by yourself! Method parameters structure might
grow in the future! Be warned.
Internal implementation of this method can use internal or passed
arguments, so please do not cheat and if you are not
overriding it, pass the original arguments to super class.
MUIM_NList_Display --
SYNOPSIS
DoMethod(obj,MUIM_NList_Display,APTR entry,ULONG entry_pos,
STRPTR *strings,STRPTR *preparses);
FUNCTION
This method is called ONLY by NList.mcc when application is
displaying entry f.e. when MUI_Redraw(), MUIM_NList_Redraw or
MUIM_NList_RedrawEntry are called. So, this method is only useful
within NList.mcc subclass, function method should looks like
normal MUIA_NList_DisplayHook or MUIA_NList_DisplayHook2 hook
function. If your subclass will not override this method
NList.mcc implementation will be used, and it will call
MUIA_NList_DisplayHook or MUIA_NList_DisplayHook2 hook in that
case.
INPUTS
entry - Entry pointer returned by f.e. MUIM_NList_Construct,
MUIA_NList_ConstructHook or MUIA_NList_ConstructHook2
hooks.
entry_pos - Entry position.
strings - Pointer to strings table.
preparses - Pointer to preparse strings table.
RESULT
Currently undefined. If you are overriding it completely, please
return 0, if not, use the value returned by super class!
NOTE
Do not call it by yourself! Method parameters the structure might
grow in the future! Be warned.
Internal implementation of this method can use internal or passed
arguments, so please do not cheat and if you are not
overriding it, pass the original arguments to super class.
MUIM_NList_DoMethod --
SYNOPSIS
DoMethod(obj,MUIM_NList_DoMethod,LONG pos,
APTR DestObj,ULONG FollowParams,ULONG method,...);
FUNCTION
The given method will be executed for each selected entry, the
active entry, all entries, or one specified entry of the NList
object.
Each DoMethod() can be done on the NList object, its _app object,
a specified object, or the entry pointer if (and only if) it's
an object.
Following arguments can be automatically adjusted for each call
using special values, like in the MUIM_Notify method (you must
specified the numer of following argument too, as there will be
copied in a temporary buffer - alloced in the stack).
INPUTS
pos - the entry number for which you want to do the method.
special values :
MUIV_NList_DoMethod_Active do it for the active entry.
MUIV_NList_DoMethod_Selected do it for all selected entries.
MUIV_NList_DoMethod_All do it
DestObj - the object on which the method will be done.
special values :
MUIV_NList_DoMethod_Entry use entry pointer as target object for method.
MUIV_NList_DoMethod_Self use the NList object as target for method.
MUIV_NList_DoMethod_App use the _app(NList object) as target for method.
FollowParams - the number of following parameters (including "method").
(maximum 40 to prevent errors and stack overflow)
method - the method which will be done.
... - the method parameters.
special values :
MUIV_NList_EntryValue replaced by the "current" entry pointer.
MUIV_NList_EntryPosValue replaced by the "current" entry number.
MUIV_NList_SelfValue replaced by the NList object.
MUIV_NList_AppValue replaced by _app(NList object)
NOTES
Don't use this to do things on the NList object when a specific way
to do it exists (don't use it to remove entries in the nlist object
itself for example).
When using it in a notification, MUIV_TriggerValue and MUIV_TriggerValue
special values will be replaced by the notify superclass as usual.
EXAMPLES
Insert all entries from nlist L1 to nlist L2 :
DoMethod(L1, MUIM_NList_DoMethod, MUIV_NList_DoMethod_All,
L2, 3,
MUIM_NList_InsertSingle, MUIV_NList_EntryValue, MUIV_NList_Insert_Bottom);
(it would be better to make set(L2,MUIA_NList_Quiet,TRUE) before and
set(L2,MUIA_NList_Quiet,FALSE) after when there are many entries...)
If the entries of nlist L1 are objects (and only in that case), it can be done
to call a method (MUIM_Foo,x) for each selected of them :
DoMethod(L1, MUIM_NList_DoMethod, MUIV_NList_DoMethod_Selected,
MUIV_NList_DoMethod_Entry, 2,
MUIM_Foo,x);
MUIM_NList_DropDraw --
SYNOPSIS
DoMethod(obj,MUIM_NList_DropDraw, LONG pos, LONG type,
LONG minx,LONG maxx,LONG miny,LONG maxy);
FUNCTION
This method MUST NOT be called directly !
It will be called by NList, and will draw the drop mark previously fixed
(pos and type) by MUIM_NList_DropType within the minx, maxx, miny, maxy
in the _rp(obj) rasport. Do draw outside of the given box because only
the corresponding NList entry will be refreshed to erase what is drawn in
that method.
Calling the supermethod (so the builtin MUIM_NList_DropDraw method) will draw
the standard dropmark specified by (type & MUIV_NList_DropType_Mask), so
MUIV_NList_DropType_None,MUIV_NList_DropType_Above,MUIV_NList_DropType_Below
or MUIV_NList_DropType_Onto.
You can draw directly in the rastport (or a clone of it) in that method,
because it will be called from the Draw method within the DragReport in
Refresh mode.
MUIM_NList_DropEntryDrawErase --
SYNOPSIS
DoMethod(obj,MUIM_NList_DropEntryDrawErase,LONG type,LONG drawpos,LONG erasepos);
FUNCTION
This method MUST NOT be called directly !
It will be called by NList while the DragReport just before the redraw
which will draw a new mark or erase the old one.
This method can be used to change something so your displayhook will return
something different for the marked entry, like changing its color or making
it bold or italic.
Don't call the superclass unless you know that the superclass uses it.
You should return 0.
INPUTS
type has the same meaning as *type in MUIM_NList_DropType, it will be useless
in most cases (and has no meaning at all for erasepos).
drawpos is the entry number which will be draw with a dropmark, -1 mean none.
erasepos is the entry number which is not any more the dropmark one, -1 mean none.
MUIM_NList_DropType --
SYNOPSIS
DoMethod(obj,MUIM_NList_DropType, LONG *pos,LONG *type,
LONG minx,LONG maxx,LONG miny,LONG maxy,
LONG mousex,LONG mousey);
FUNCTION
This method MUST NOT be called directly !
It will be called by NList while the DragReport, with default *pos and *type
values depending on the drag pointer position that you can modify as you want.
Default *type can be MUIV_NList_DropType_Above or MUIV_NList_DropType_Below.
You can change it to any of MUIV_NList_DropType_None,MUIV_NList_DropType_Above,
MUIV_NList_DropType_Below and MUIV_NList_DropType_Onto if you want, using
the mouse position and the entry box.
You can make your own *type value as long as you don't set it in
MUIV_NList_DropType_Mask, and so draw what you want depending on that value
in the MUIM_NList_DropDraw method.
Note that any MUIV_NList_DropType_Below *type will be changed to
MUIV_NList_DropType_Above with a *pos incremented by 1 just after the
return of that method.
If you change the *pos, the list will be scrolled to see it (if the value is
correct).
getting MUIA_NList_DropType or MUIA_NList_DropMark will return the same values
as *pos and *type.
If your subclass is a direct NList subclass, then there is no need to call
the supermethod which has done nothing at all !
MUIM_NList_Exchange --
SYNOPSIS
DoMethod(obj,MUIM_NList_Exchange,LONG pos1, LONG pos2);
FUNCTION
Same function as List.mui/MUIM_List_Exchange.
Exchange two entries in a NList object.
INPUTS
pos1 - number of the first entry.
pos2 - number of the second entry.
MUIV_NList_Exchange_Top
MUIV_NList_Exchange_Active
MUIV_NList_Exchange_Bottom
MUIV_NList_Exchange_Next only valid for second parameter
MUIV_NList_Exchange_Previous only valid for second parameter
MUIM_NList_GetEntry --
SYNOPSIS
DoMethod(obj,MUIM_NList_GetEntry,LONG pos, APTR *entry);
FUNCTION
Same function as List.mui/MUIM_List_GetEntry.
SPECIAL INPUTS
MUIV_NList_GetEntry_Active give active entry (or NULL if none)
MUIM_NList_GetEntryInfo --
SYNOPSIS
DoMethod(obj,MUIM_NList_GetEntryInfo,struct MUI_NList_GetEntryInfo *res);
FUNCTION
You get useful information about some entry from its number,
or from the real line number which can be different when there
is word wrap in the list.
INPUTS
res - pointer to a MUI_NList_GetEntryInfo struct :
LONG pos; number of entry you want info about */
LONG line; real line number */
LONG entry_pos; entry number of returned entry ptr */
APTR entry; entry pointer */
LONG wrapcol; NOWRAP, WRAPCOLx, or WRAPPED|WRAPCOLx */
LONG charpos; start char number in string (unused if NOWRAP) */
LONG charlen; string length (unused if NOWRAP) */
if pos is MUIV_NList_GetEntryInfo_Line then the method will
use the line number to search infos, or else the line will
be set to its correct number for the value of pos.
entry is the entry ptr, think that if it's a word wrapped
entry then it come from the returned entry_pos entry.
Think, too, that if wrapcol tell you that it's a WRAPPED entry,
only the WRAPCOLx col is drawn, from the charpos position
in the string returned by DisplayHook for the column and for
entry_pos/entry.
MUIM_NList_GetPos --
SYNOPSIS
DoMethod(obj,MUIM_NList_GetPos,APTR entry,LONG *pos);
FUNCTION
Give the (next) entry number which have the given entry number.
It's the entry ptr which is stored in the list, ie the one returned
by the ConstructHook if any.
INPUTS
entry - Entry ptr of the entry you want to get the pos.
pos - a pointer to longword that will hold the next entry number
of the given entry ptr. Must be set to MUIV_NList_GetPos_Start
if you want to search from the beginning of the list.
Is set to MUIV_NList_GetPos_End no more is found.
MUIM_NList_GetSelectInfo --
SYNOPSIS
DoMethod(obj,MUIM_NList_GetSelectInfo,struct MUI_NList_GetSelectInfo *res);
FUNCTION
Useful information about selected entries state is provided.
INPUTS
res - pointer to a MUI_NList_GetSelectInfo struct :
LONG start num of first selected *REAL* entry/line (first of wrapped from which start is issued)
LONG end num of last selected *REAL* entry/line (first of wrapped from which start is issued)
LONG num not used
LONG start_column column of start of selection in 'start' entry
LONG end_column column of end of selection in 'end' entry
LONG start_pos char pos of start of selection in 'start_column' entry
LONG end_pos char pos of end of selection in 'end_column' entry
LONG vstart num of first visually selected entry (ie can be the second or third line of a word wrap entry)
LONG vend num of last visually selected entry (ie can be the second or third line of a word wrap entry)
LONG vnum number of visually selected entries
NOTE
If no entry is selected, then start, end, vstart, vend are -1, vnum is 0.
When start_column, end_column, start_pos, end_pos are -1 then the whole line/entry/column
is selected.
start_column, end_columb, start_pos and end_pos have the same meaning than
parameters passed to the MUIA_NList_CopyEntryToClipHook.
remember that in case of automatically added word wrapped entries, only
the concerned column have any contents. You get that case for 'vstart'
when 'start' is different, and for 'end' when 'vend' is different.

MUIM_NList_SelectChange -- Called on every selection change (V19.98)
SYNOPSIS
DoMethod(obj,MUIM_NList_SelectChange,LONG pos, LONG state, ULONG flags);
FUNCTION
This method cannot/should not be called. Its purpose is only to indicate
selection state changes of entries in a more powerful form than
MUIA_NList_SelectChange does.
It is only called when you are in line mode ie. MUIA_NList_TypeSelect is
set to MUIV_NList_TypeSelect_Line, which is the default.
pos - The position of the (un)selected entry. Can be
MUIV_NList_Active_Off or something.
state - The resulting state of the entry which can be MUIV_NList_Select_On,
MUIV_NList_Select_Off or MUIV_NList_Select_Active.
flags - Can be MUIV_NList_SelectChange_Flag_Multi for now which means
that the entry was selected while holding down the mouse button.
INPUTS
MUIM_NList_SetActive -- make a specific entry the active one (v20.125)
SYNOPSIS
DoMethod(obj, MUIM_NList_SetActive, LONG pos, ULONG flags);
FUNCTION
This method is a replacement function for the old-style way of making an
entry active via a simple set(obj, MUIA_NList_Active, pos) call. While the
old method still works, this new function has the advantage that it allows
to set an entry active together with making it immediately visible in the
listview.
Previously, a developer had to do a combination of a set() call to set
MUIA_NList_Active and then immediately perform a MUIM_NList_Jump function
call so that the entry becomes visible at the specific position. With this
new function both operations are combined, potentially allowing future
enhancements to be added via the additional 'flags' variable.
INPUTS
The parameter description is as followed:
pos - The position (int) of the entry which should be made the new
active entry. This can also be MUIV_NList_Active_XXXX values as
explained in the MUIA_NList_Active documentation. Furthermore,
pos might also be a perfect pointer to the entry directly in
case you have specified the correct flag.
flags - Can be a combination of the following flags:
MUIV_NList_SetActive_Entry:
the parameter 'pos' will be a pointer to the entry rather
than the position (int) of the entry to be made active. If
this flag is set NList will perform an internal GetPos()
operation to first obtain the position and then set
this entry active.
MUIV_NList_SetActive_Jump_Center:
Together with making the specified entry the new active one
the listview will also be scrolled so that the new entry
will be shown centered instead of having it simply visible.
MUIM_NList_SetColumnCol --
SYNOPSIS
DoMethod(obj,MUIM_NList_SetColumnCol,LONG column,LONG col);
FUNCTION
set which displayhook col is at the visible column.
INPUTS
column number of the column (visible).
if MUIV_NList_SetColumnCol_Default then the given (diplayhook) col
will come back to its default/original (from List_Format) position.
col col number (displayhook one).
if MUIV_NList_SetColumnCol_Default then the given visible column
will come back to its default/original (from List_Format) position.
both set to MUIV_NList_SetColumnCol_Default make all columns
come back to their default/original (from List_Format) position.
RESULT
None.
NOTE
MUIM_NList_SetColumnCol always exchanges the moved column with the column
which was where it moved.
MUIM_NList_Sort --
SYNOPSIS
DoMethod(obj,MUIM_NList_Sort);
FUNCTION
Same function as List.mui/MUIM_List_Sort.
MUIM_NList_Sort2 --
SYNOPSIS
DoMethod(obj,MUIM_NList_Sort2,LONG sort_type, LONG sort_type_add);
FUNCTION
Same function as MUIM_NList_Sort but will set MUIA_NList_SortType
before starting the sort.
It is really useful only if you use MUIA_NList_CompareHook2 instead
of classic MUIA_NList_CompareHook so your hook will be able to do
different type of sort when NList_SortType change.
INPUTS
sort_type - The new MUIA_NList_SortType value (see below).
sort_type_add - If 0 then sort_type will be the new MUIA_NList_SortType,
else if current MUIA_NList_SortType & MUIV_NList_SortTypeValue_Mask
is same as sort_type then sort_type_add will be added to the
MUIA_NList_SortType value,
else sort_type will be the new MUIA_NList_SortType.
See examples for special values.
EXAMPLES
Often, this method will be used to sort multicolumn list in different
ways when the user click on title buttons :
DoMethod(list,MUIM_Notify,MUIA_NList_TitleClick, MUIV_EveryTime,
list, 3, MUIM_NList_Sort2, MUIV_TriggerValue, MUIV_NList_SortTypeAdd_xxx);
if MUIV_NList_SortTypeAdd_None then the hook sort_type value will be the column
number.
if MUIV_NList_SortTypeAdd_2Values then the hook sort_type value will be a cycle of
values which change on each click :
o Column number (first time)
o Column number + MUIV_NList_SortTypeAdd_2Values
o back to column number ...
if MUIV_NList_SortTypeAdd_4Values then the hook sort_type value will be a cycle of
values which change on each click :
o Column number (first time)
o Column number + MUIV_NList_SortTypeAdd_4Values
o Column number + MUIV_NList_SortTypeAdd_4Values*2
o Column number + MUIV_NList_SortTypeAdd_4Values*3
o back to column number ...
See NList-Demo program.
MUIM_NList_Sort3 --
SYNOPSIS
DoMethod(obj,MUIM_NList_Sort3,LONG sort_type, LONG sort_type_add, LONG which);
FUNCTION
Same function as MUIM_NList_Sort2 but will set MUIA_NList_SortType,
MUIA_NList_SortType2 or both before starting the sort.
When using MUIV_NList_Sort3_SortType_Both the method will change
MUIA_NList_SortType exactly the same way as MUIM_NList_Sort2 would do
it, then copy that value to MUIA_NList_SortType2.
It is really useful only if you use MUIA_NList_CompareHook2 instead
of classic MUIA_NList_CompareHook so your hook will be able to do
a different type of sort when NList_SortType changes.
INPUTS
sort_type - The new MUIA_NList_SortType/2 value.
sort_type_add - If 0 then sort_type will be the new MUIA_NList_SortType/2,
else if current MUIA_NList_SortType/2 & MUIV_NList_SortTypeValue_Mask
is same as sort_type then sort_type_add will be added to the
MUIA_NList_SortType/2 value,
else sort_type will be the new MUIA_NList_SortType/2.
which - MUIV_NList_Sort3_SortType_1 set MUIA_NList_SortType value.
MUIV_NList_Sort3_SortType_2 set MUIA_NList_SortType2 value.
MUIV_NList_Sort3_SortType_Both set MUIA_NList_SortType value
then copy it to MUIA_NList_SortType2.
EXAMPLES
See NList-Demo program.
MUIM_NList_TestPos --
SYNOPSIS
DoMethod(obj,MUIM_NList_TestPos,LONG x, LONG y, struct MUI_NList_TestPos_Result *res);
FUNCTION
Find out which information of a list which is currently
displayed at a certain position.
You must give a pointer to a valid MUI_NList_TestPos_Result struct.
Set x AND y to MUI_MAXMAX to get infos about the last click position !
See NList_mcc.h to know what values will be set in the struct.
Preset char_number to -2 in the struct to not get char_number and char_xoffset
informations. It's useful if you don't need them because it will be
faster for the method without finding them. The -2 value will stay valid
for next call.
You'll get char number from what you return from the DisplayHook if there is
one, else from the beginning of the string/entry ptr.
Be aware: if you use MUIM_List_TestPos you have to give a pointer to a
struct MUI_List_TestPos_Result, and you will get same infos as using a List object.
It wasn't done as before, making enforcer hits when trying to use NList
or NFloattext with a Listview instead of a NListview (avoid it please, it's not
done for it as Listview try to make many things itself, with possible conficts),
because struct MUI_NList_TestPos_Result is bigger !!!
NOTE
column in the struct MUI_NList_TestPos_Result is the visible column number !
MUIM_NList_UseImage --
SYNOPSIS
DoMethod(obj,MUIM_NList_UseImage,Object *obj, ULONG imgnum, ULONG flags);
FUNCTION
To use MUIM_NList_CreateImage/MUIM_NList_DeleteImage
as you should, make a NList subclass which calls them
from Setup() and Cleanup(), and it's sometimes complicated.
To avoid that, use MUIM_NList_UseImage. NList will
store the Bitmap/Bodychunk object you give and will make
CreateImage and DeleteImage itself !
MUIM_NList_UseImage can use same object as MUIM_NList_CreateImage !
NULL is a valid obj. It will erase any previously UseImage
with the same imgnum.
The imgnum you give is the number that you will use in
\33o[<n>] sequence as the <n> number.
MUIM_NList_UseImage will accept 0 <= imgnum < 8192, anyway
use small value if you can because an array will be allocated
with the biggest imgnum value as size to store the
Bitmap/Bodychunk objects.
DoMethod(obj,MUIM_NList_UseImage, NULL, MUIV_NList_UseImage_All, 0)
will set NULL to all stored objects, so you willll be able to dispose
your Bitmap/Bodychunk objects if you want, without waiting for the
NList object dispose.
flags is the same than for MUIM_NList_CreateImage (0 unless special case).
RESULT
TRUE if succeeded to store the obj (and allocate the array
if needed), else FALSE.
There is no way to know if the MUIM_NList_CreateImage
needed to draw will succeed/has succeeded.
ATTENTION:
The given Bitmap/Bodychunk object MUST be valid until the
NList object is disposed or you set another object (or NULL)
at the same imgnum !
The Bitmap/Bodychunk object can be shared with other NList
object because NList just use it to get informations, anyway
you mustn't change informations of that object. If you to do
so, do a UseImage,NULL,x , change it then do UseImage,imgobj,x
again.

NListtree.mcc/
There are two possible entry-types in a NListtree class list:
Leaves and nodes. Leaves are simple entries which have no special
features except they are holding some data. Nodes are almost
the same type, holding data too, but having a list attached
where you can simply add other entries which can be again leaves
or nodes.
Every node is structured as follows:
struct MUI_NListtree_TreeNode {
struct MinNode tn_Node;
STRPTR tn_Name;
UWORD tn_Flags;
APTR tn_User;
};
It contains a name field tn_Name, flags tn_Flags and a pointer to
user data tn_User.
The tn_Flags field can hold the following flags:
TNF_LIST The node contains a list where other nodes
can be inserted.
TNF_OPEN The list node is open, sub nodes are displayed.
TNF_FROZEN The node doesn't react on doubleclick or
open/close by the user.
TNF_NOSIGN The indicator of list nodes isn't shown.
TNF_SELECTED The entry is currently selected.
These flags, except TNF_SELECTED, can be used in
MUIM_NListtree_Insert at creation time. They will be passed to
the newly created entry. Also you can do a quick check about the
state and kind of each entry. But DO NOT EVER modify any flag
yourself or NListtree will crash. Be warned!
*********************************************************************
THE ABOVE STRUCT IS READ-ONLY!! NEVER CHANGE ANY ENTRY OF THIS
STRUCTURE DIRECTLY NOR THINK ABOUT THE CONTENTS OF ANY PRIVATE
FIELD OR YOU WILL DIE IN HELL!
*********************************************************************
You can create very complex tree structures. NListtree only uses
one list which holds all information needed and has no extra
display list like other list tree classes ;-)
The tree nodes can be inserted and removed, sorted, moved, exchanged,
renamed or multi selected. To sort you can also drag&drop them.
Modifications can be made in relation to the whole tree, to only one
level, to a sub-tree or to only one tree node.
The user can control the listtree by the MUI keys, this means a node
is opened with "Right" and closed with "Left". Check your MUI prefs
for the specified keys.
You can define which of the columns will react on double-clicking.
The node toggles its status from open or closed and vice versa.
Drag&Drop capabilities:
If you set MUIA_NList_DragSortable to TRUE, the list tree will
become active for Drag&Drop. This means you can drag and drop
entries on the same list tree again. While dragging an indicator
shows where to drop.
Drag a Drop on Result
leaf leaf Exchange leaves.
node leaf Nothing happens.
entry closed node Move entry, the compare hook is used.
entry open node Move entry to defined position.
You can not drop an entry on itself, nor can you drop an opened node on
any of its members.
To exchange data with other objects, you have to create your own
subclass of NListtree class and react on the drag methods.
MUIA_NListtree_Active -- [.SG], struct MUI_NListtree_TreeNode *
SPECIAL VALUES
MUIV_NListtree_Active_Off
MUIV_NListtree_Active_Parent
MUIV_NListtree_Active_First
MUIV_NListtree_Active_FirstVisible
MUIV_NListtree_Active_LastVisible
FUNCTION
Setting this attribute will move the cursor to the defined tree node
if it is visible. If the node is in an opened tree the listview is
scrolling into the visible area. Setting MUIV_NListtree_Active_Off will
vanish the cursor.
MUIV_NListtree_Active_First/FirstVisible/LastVisible are special values
for activating the lists first or the top/bottom visible entry.
See MUIA_NListtree_AutoVisible for special activation features.
If this attribute is read it returns the active tree node. The result
is MUIV_NListtree_Active_Off if there is no active entry.
NOTIFICATIONS
You can create a notification on MUIA_NListtree_Active. The
TriggerValue is the active tree node.
MUIA_NListtree_ActiveList -- [..G], struct MUI_NListtree_TreeNode *
SPECIAL VALUES
MUIV_NListtree_ActiveList_Off
FUNCTION
If this attribute is read it returns the active list node. The
active list node is always the parent of the active entry.
The result is MUIV_NListtree_ActiveList_Off if there is no
active list (when there is no active entry).
NOTIFICATIONS
You can create notifications on MUIA_NListtree_ActiveList. The
TriggerValue is the active list node.
MUIA_NListtree_AutoVisible -- [ISG], struct MUI_NListtree_TreeNode *
SPECIAL VALUES
MUIV_NListtree_AutoVisible_Off
MUIV_NListtree_AutoVisible_Normal
MUIV_NListtree_AutoVisible_FirstOpen
MUIV_NListtree_AutoVisible_Expand
FUNCTION
Set this to make your list automatically jump to the active
entry.
MUIV_NListtree_AutoVisible_Off:
The display does NOT scroll the active entry into the
visible area.
MUIV_NListtree_AutoVisible_Normal:
This will scroll the active entry into the visible area
if it is visible (entry is a member of an open node).
This is the default.
MUIV_NListtree_AutoVisible_FirstOpen:
Nodes are not opened, but the first open parent node of
the active entry is scrolled into the visible area if the
active entry is not visible.
MUIV_NListtree_AutoVisible_Expand:
All parent nodes are opened until the first open node is
reached and the active entry will be scrolled into the
visible area.
MUIA_NListtree_CloseHook -- [IS.], struct Hook *
SPECIAL VALUES
FUNCTION
The close hook is called after a list node is closed, then the list
can be changed.
The close hook will be called with the hook in A0, the object in A2
and a MUIP_NListtree_CloseMessage struct in A1 (see nlisttree_mcc.h).
To remove the hook set this to NULL.
MUIA_NListtree_CompareHook -- [IS.], struct Hook *
SPECIAL VALUES
MUIV_NListtree_CompareHook_Head
MUIV_NListtree_CompareHook_Tail
MUIV_NListtree_CompareHook_LeavesTop
MUIV_NListtree_CompareHook_LeavesMixed
MUIV_NListtree_CompareHook_LeavesBottom
FUNCTION
Set this attribute to your own hook in order to sort the entries in
the list tree by your own way.
When you sort your list or parts of your list via MUIM_NListtree_Sort,
using the insert method with MUIV_NListtree_Insert_Sort or dropping an
entry on a closed node, this compare hook is called.
There are some builtin compare hooks available, called:
MUIV_NListtree_CompareHook_Head
Any entry is inserted at the head of the list.
MUIV_NListtree_CompareHook_Tail
Any entry is inserted at the tail of the list.
MUIV_NListtree_CompareHook_LeavesTop
Leaves are inserted at the top of the list, nodes at bottom. They are
alphabetically sorted.
MUIV_NListtree_CompareHook_LeavesMixed
The entries are only alphabetically sorted.
MUIV_NListtree_CompareHook_LeavesBottom
Leaves are inserted at bottom of the list, nodes at top. They are
alphabetically sorted. This is default.
The hook will be called with the hook in A0, the object in A2 and
a MUIP_NListtree_CompareMessage struct in A1 (see nlisttree_mcc.h). You
should return something like:
<0 (TreeNode1 < TreeNode2)
0 (TreeNode1 == TreeNode2)
>0 (TreeNode1 > TreeNode2)
MUIA_NListtree_ConstructHook -- [IS.], struct Hook *
SPECIAL VALUES
MUIV_NListtree_ConstructHook_String
MUIV_NListtree_ConstructHook_Flag_AutoCreate
If using the KeepStructure feature in MUIM_NListtree_Move or
MUIM_NListtree_Copy, this flag will be set when calling your
construct hook. Then you can react if your hook is not simply
allocating memory.
FUNCTION
The construct hook is called whenever you add an entry to your
listtree. The pointer isn't inserted directly, the construct hook is
called and its result code is added.
When an entry shall be removed the corresponding destruct hook is
called.
The construct hook will be called with the hook in A0, the object in
A2 and a MUIP_NListtree_ConstructMessage struct in A1 (see
nlisttree_mcc.h).
The message holds a standard kick 3.x memory pool pointer. If you want,
you can use the exec or amiga.lib functions for allocating memory
within this pool, but this is only an option.
If the construct hook returns NULL, nothing will be added to the list.
There is a builtin construct hook available called
MUIV_NListtree_ConstructHook_String. This expects that the field
'tn_User' in the treenode is a string pointer (STRPTR), whose
string is copied.
MUIV_NListtree_DestructHook_String must be used in this case!
To remove the hook set this to NULL.
NEVER pass a NULL pointer when you have specified the internal string
construct/destruct hooks or NListtree will die!
MUIA_NListtree_CopyToClipHook -- [IS.],
SPECIAL VALUES
MUIV_NListtree_CopyToClipHook_Default
FUNCTION
This works similarly to MUIA_NListtree_DisplayHook, but is
called when the NListtree object want to make a clipboard copy.
You can return only one string pointer. If you return NULL,
nothing will be copied. If you return -1, the entry will be
handled as a normal string and the name field is used.
The built-in hook skips all ESC sequences and adds a tab char
between columns.
MUIA_NListtree_DestructHook -- [IS.], struct Hook *
SPECIAL VALUES
MUIV_NListtree_DestructHook_String
FUNCTION
Set up a destruct hook for your listtree. The destruct hook is called
whenevere you remove an entry from the listtree. Here you can free memory
which was allocated by the construct hook before.
The destruct hook will be called with the hook in A0, the object
in A2 and a MUIP_NListtree_DestructMessage struct in A1 (see
nlisttree_mcc.h).
The message holds a standard kick 3.x memory pool pointer. This pool must
be used when you have used it inside the construct hook to
allocate pooled memory.
There is a built-in destruct hook available called
MUIV_NListtree_DestructHook_String. This expects that the 'User' data
in the treenode is a string and you have used
MUIV_NListtree_ConstructHook_String in the construct hook!
To remove the hook set this to NULL.
MUIA_NListtree_DisplayHook -- [IS.],
SPECIAL VALUES
FUNCTION
You have to supply a display hook to specify what should be shown in
the listview, otherwise only the name of the nodes is displayed.
The display hook will be called with the hook in A0, the object in
A2 and a MUIP_NListtree_DisplayMessage struct in A1 (see nlisttree_mcc.h).
The structure holds a pointer to a string array containing as many
entries as your listtree may have columns. You have to fill this
array with the strings you want to display. Check out that the array
pointer of the tree column is set to NULL, if the normal name of the
node should appear.
You can set a preparse string in Preparse for the corresponding col
element. Using it you'll be able to avoid copying the string in a
buffer to add something in the beginning of the col string.
The display hook also gets the position of the current entry as
additional parameter. It is stored in the longword preceding the col
array (don't forget it's a LONG).
You can set the array pointer of the tree column to a string, which is
displayed instead of the node name. You can use this to mark nodes.
See MUIA_NList_Format for details about column handling.
To remove the hook and use the internal default display hook set this
to NULL.
MUIA_NListtree_DoubleClick -- [ISG], ULONG
SPECIAL VALUES
MUIV_NListtree_DoubleClick_Off
MUIV_NListtree_DoubleClick_All
MUIV_NListtree_DoubleClick_Tree
MUIV_NListtree_DoubleClick_NoTrigger
FUNCTION
A doubleclick opens a node if it was closed, it is closed if the node
was open. You have to set the column which should do this.
Normally only the column number is set here, but there are special
values:
MUIV_NListtree_DoubleClick_Off:
A doubleclick is not handled.
MUIV_NListtree_DoubleClick_All:
All columns react on doubleclick.
MUIV_NListtree_DoubleClick_Tree
Only a doubleclick on the defined tree column is recognized.
MUIV_NListtree_DoubleClick_NoTrigger:
A doubleclick is not handled and not triggered!
NOTIFICATION
The TriggerValue of the notification is the tree node you have double-
clicked, you can GetAttr() MUIA_NListtree_DoubleClick for the column
number. The struct 'MUI_NListtree_TreeNode *'is used for trigger.
The notification is done on leaves and on node columns, which are not
set in MUIA_NListtree_DoubleClick.
MUIA_NListtree_DragDropSort -- [IS.], BOOL
SPECIAL VALUES
FUNCTION
Setting this attribute to FALSE will disable the ability to sort the
list tree by drag & drop. Defaults to TRUE.
MUIA_NListtree_DropTarget -- [..G], ULONG
SPECIAL VALUES
FUNCTION

the entry was dropped. The relative position (above etc.) can be
obtained by reading the attribute MUIA_NListtree_DropType.
MUIA_NListtree_DropTargetPos -- [..G], ULONG
SPECIAL VALUES
FUNCTION
After a successful drop operation, this value holds the integer
position of the entry where the dragged entry was dropped. The
entry itself can be obtained by reading MUIA_NListtree_DropTarget,
the relative position (above etc.) can be obtained by reading the
attribute MUIA_NListtree_DropType.
MUIA_NListtree_DropType -- [..G], ULONG
SPECIAL VALUES
MUIV_NListtree_DropType_None
MUIV_NListtree_DropType_Above
MUIV_NListtree_DropType_Below
MUIV_NListtree_DropType_Onto

relative to the value of MUIA_NListtree_DropTarget/DropTargetPos.
NOTIFICATION
MUIA_NListtree_DupNodeName -- [IS.], BOOL
SPECIAL VALUES
FUNCTION
If this attribute is set to FALSE the names of the node will not be
duplicated, only the string pointers are used. Be careful the strings
have to be valid every time.
NOTIFICATION
MUIA_NListtree_EmptyNodes -- [IS.], BOOL
SPECIAL VALUES
FUNCTION
Setting this attribute to TRUE will display all empty nodes as leaves,
this means no list indicator is shown. Nevertheless the entry is
handled like a node.

MUIV_NListtree_FindNameHook_PointerCompare
Do only a pointer comparison. This is a pointer subtraction
to fit into the rules. It returns the difference (~0) of the
two fields if there is no match.
FUNCTION
You can install a FindName hook to specify your own search
criteria.
The find name hook will be called with the hook in A0, the object in
A2 and a MUIP_NListtree_FindNameMessage struct in A1
(see nlisttree_mcc.h). It should return ~ 0 for entries which are
not matching the pattern and a value of 0 if a match.
The find name message structure holds a pointer to a string
containing the name to search for and pointers to the name- and user-
field of the node which is currently processed.
The MUIV_NListtree_FindNameHook_CaseSensitive will be used as default.
NOTIFICATION

a pointer subtraction to fit into the rules. It returns
the difference (~0) of the two user fields if there is no match.
FUNCTION
You can install a FindUserData hook to specify your own search
criteria.
The find user data hook will be called with the hook in A0, the object
in A2 and a MUIP_NListtree_FindUserDataMessage struct in A1
(see nlisttree_mcc.h). It should return ~ 0 for entries which are
not matching the pattern and a value of 0 if a match.
The find user data message structure holds a pointer to a string
containing the data to search for and pointers to the user- and name-
field of the node which is currently processed.
MUIV_NListtree_FindUserDataHook_CaseSensitive will be used as default.

Iterate through the selected entries of a tree. This method steps
through the contents of a (multi select) list tree and returns
every entry that is currently selected. When no entry is selected
but an entry is active, only the active entry will be returned.
This behaviour will result in not returning the active entry when
you have some other selected entries somewhere in your list. Since
the active entry just acts as some kind of cursor mark, this seems
to be the only sensible possibility to handle multi selection
together with keyboard control.
INPUTS
treenode - A pointer to a pointer of struct MUI_NListtree_TreeNode
that will hold the returned entry. Must be set to
MUIV_NListtree_NextSelected_Start at start of iteration

MUIM_NListtree_Rename -- Rename the specified node. (V1)
SYNOPSIS
struct MUI_NListtree_TreeNode *treenode =
DoMethod(obj, MUIM_NListtree_Rename,
struct MUI_NListtree_TreeNode *treenode,
STRPTR newname, ULONG flags);
FUNCTION
Rename the specified node.
If you want to rename the tn_User field (see flags below), the construct
and destruct hooks are used!
If you have not specified these hooks, only the pointers will be copied.
INPUTS
treenode - Specifies the node which should be renamed.
MUIV_NListtree_Rename_TreeNode_Active:
Rename the active tree node.
newname - The new name or pointer.
flags:
MUIV_NListtree_Rename_Flag_User
The tn_User field is renamed.
MUIV_NListtree_Rename_Flag_NoRefresh
The list entry will not be refreshed.
RESULT
Returns the pointer of the renamed tree node.
EXAMPLE
// Rename the active tree node.
DoMethod(obj, MUIM_NListtree_Rename,
MUIV_NListtree_Rename_TreeNode_Active,
"Very new name", 0);

MUIM_NListtree_Select -- Select the specified tree node. (V1)
SYNOPSIS
DoMethod(obj, MUIM_NListtree_Select,
struct MUI_NListtree_TreeNode *treenode, LONG seltype,
LONG selflags, LONG *state);
FUNCTION
Select or unselect a tree entry or ask an entry about its state.
See special values for completeness.
INPUTS
treenode - The tree node to be selected/unselected/asked.
MUIV_NListtree_Select_Active For the active entry.
MUIV_NListtree_Select_All For all entries.
MUIV_NListtree_Select_Visible For all visible entries.
seltype - Type of selection/unselection/ask
MUIV_NListtree_Select_Off Unselect entry.
MUIV_NListtree_Select_On Select entry.
MUIV_NListtree_Select_Toggle Toggle entries state.
MUIV_NListtree_Select_Ask Just ask about the state.
selflags - Some kind of specials.
MUIV_NListtree_Select_Flag_Force
Adding this flag to seltype forces the selection by
bypassing the multi test hook.
state - Pointer to a longword. If not NULL, it will be filled
with the current selection state of the entry.
RESULT
EXAMPLE
// Select the active entry.
LONG retstate;
DoMethod(obj, MUIM_NListtree_Select,
MUIV_NListtree_Select_Active, MUIV_NListtree_Select_On,
0, &retstate);
// We must check this, because the multi-test hook may
// cancel our selection.
if (retstate == MUIV_NListtree_Select_On) {
...
}
NOTES
If ( treenode == MUIV_NListtree_Select_All ) and
( seltype == MUIV_NListtree_Select_Ask ), state will be filled
with the total number of selected entries.
NEW for final 18.6:
If (treenode == MUIV_NListtree_Select_Active ) and
( seltype == MUIV_NListtree_Select_Ask ), state will be the
active entry, if any, or NULL.
If only the active entry is selected, has a cursor mark (see
MUIM_NListtree_NextSelected for that), you will receive 0 as
the number of selected entries.
BUGS
MUIM_NListtree_Sort -- Sort the specified list node. (V1)
SYNOPSIS
DoMethod(obj, MUIM_NListtree_Sort,
struct MUI_NListtree_TreeNode *listnode,
ULONG flags);
FUNCTION
Sort the specified list node using the sort hook.
INPUTS
listnode - List node to sort.
MUIV_NListtree_Sort_ListNode_Root
Sort the root list.
MUIV_NListtree_Sort_ListNode_Active
Sort the list node of the active entry.
MUIV_NListtree_Sort_TreeNode_Active
Sorts the children of the active entry if a list.
flags - Control the part where sorting is done.
MUIV_NListtree_Sort_Flag_RecursiveOpen
Sort the list recursive. All open child nodes of the
node specified in 'listnode' will be sorted too.
MUIV_NListtree_Sort_Flag_RecursiveAll
Sort the list recursive with ALL child nodes of the
node specified in 'listnode'.
RESULT
EXAMPLE
// Sort the list of the active node.
DoMethod(obj, MUIM_NListtree_Sort,
MUIV_NListtree_Sort_ListNode_Active, 0);
NOTES
BUGS
MUIM_NListtree_TestPos -- Get information about entry at x/y pos. (V1)
SYNOPSIS
DoMethod(obj, MUIM_NListtree_TestPos, LONG xpos, LONG ypos,
struct MUI_NListtree_TestPos_Result *testposresult);
FUNCTION
Find out some information about the currently displayed entry at a
certain position (x/y-pos).
This is very useful for Drag&Drop operations.
INPUTS
xpos - X-position.
ypos - Y-position.
testposresult - Pointer to a valid MUI_NListtree_TestPos_Result
structure.
RESULT
tpr_TreeNode - The tree node under the requested position or NULL
if there is no entry displayed.
The tpr_Type field contains detailed information about the relative
position:
MUIV_NListtree_TestPos_Result_Above
MUIV_NListtree_TestPos_Result_Below
MUIV_NListtree_TestPos_Result_Onto
MUIV_NListtree_TestPos_Result_Sorted
tpr_Column - The column unter the specified position or -1 if
no valid column.
EXAMPLE
// Entry under the cursor?
struct MUI_NListtree_TestPos_Result tpres;
DoMethod(obj, MUIM_NListtree_TestPos, msg->imsg->MouseX,
msg->imsg->MouseY, &tpres);
if ( tpres.tpr_Entry != NULL )

That MCC public custom class give scrollers for a NList public custom class to make NList/NListview work near the same way as List/Listview. Most things that were handled by Listview are now handled by NList, so NListview is quite simple, anyway it's very easier to use NList with NListview than without.
Anyway, use NList without NListview if you don't want to get attached scrollers (or want to attach your own scrollers to NList - see Demo).
Note: NListview class can't use List as child but only NList, NFloattext, or a NList subclass, and NList class will not work with Listview without some conflict.

MUIV_NListview_HSB_Default 5
SPECIAL SPECIAL INPUTS
MUIV_NListview_HSB_On 0x0300
MUIV_NListview_HSB_Off 0x0100
FUNCTION
With it you can tell if you want the scrollbar to be here
always, never, automatic (not at start and appear forever if
needed) or full automatic (appear and disappear when needed).
Never is interesting if you want only one scrollbar of both
or if you want to attach your own one only for one scrollbar.
With Auto and FullAuto modes, scrollbars will not appear at
first draw of the window. If you want it to appear when the
window will be opened, you can set after creation time (not
at init) MUIA_NListview_Horiz_ScrollBar
to (MUIV_NListview_HSB_XXX|MUIV_NListview_HSB_On) where XXX
is Default, FullAuto ...
MUIV_NListview_HSB_On, MUIV_NListview_HSB_Off are used by the
NList object to make scrollbars appear/disappear.
The default is set by prefs. When prefs have not been set
it is MUIV_NListview_HSB_Auto.
MUIA_NListview_HSB_Height -- [..G], LONG
FUNCTION
Return the height of the horizontal scrollbar.
Return 0 when no horizontal scrollbar is visible.
MUIA_NListview_NList -- [I.G], Object *
FUNCTION
Same function as Listview.mui/MUIA_Listview_List.
Every NListview needs a NList (or subclass) object as child.
Specify it here.
If none is specified, NListview will create a NList object
as child, giving it the same taglist as itself.
It's the only case where NList tags given to NListview will be
taken into account.
As every other child, it will be disposed of when its parent object is disposed.

FUNCTION
Same as MUIA_NListview_Horiz_ScrollBar but for vertical
scrollbar.
The default is set by prefs. When prefs have not been set
it is MUIV_NListview_VSB_Always.
MUIA_NListview_VSB_Width -- [..G], LONG

NFloattext class is a subclass of NList class that takes a big text string as input and splits it up into several lines to be displayed. Formatting capabilities include paragraphs an justified text with word wrap. That MCC public custom class work near the same way as Floattext.
All you can do with NFloattext can be done directly using NList and its word wrap capabilities. NFloattext is here to give easy use and transition from Floattext.
Now NList package provide a Floattext.mui replacement which use directly this class. Unfortunately the replacement Floattext.mui have to have the same major release number than original Floattext.mui to be accepted by MUI, so it will have to be update with each new MUI release.
By default, MUIA_NList_Input is FALSE and MUIA_NList_TypeSelect is MUIV_NList_TypeSelect_Char, allowing char selection and copy to clipboard. If MUIA_NList_Input is set to TRUE, then MUIA_NList_TypeSelect default to MUIV_NList_TypeSelect_Line as usual.
NFloattext does not copy the string text, so it needs to copy the string line to a buffer when you do a MUIM_NFloattext_GetEntry or MUIM_List_GetEntry, so the return pointer will be invalid after next GetEntry call (the new one will be valid of course).
Using the old MUIA_Floattext_Text from standard Floatext class instead of MUIA_NFloattext_Text will make NFloattext copy the text like in Floattext class.
Note that MUIM_NList_GetEntry work as describe in NList, so as NFloattext use word wrap entries, you should use better MUIM_NFloattext_GetEntry or MUIM_List_GetEntry. Or use MUIM_NList_GetEntryInfo and MUIM_NList_GetEntry.
MUIA_NFloattext_Align -- [ISG], LONG
SPECIAL INPUTS
ALIGN_LEFT
ALIGN_CENTER
ALIGN_RIGHT
ALIGN_JUSTIFY
FUNCTION
Indicate what alignment you want.
It can be done with an escape alignment sequence
in the Format preparse string or in the text string
(for each linefeed separated lines) itself.
setting it will set MUIA_NFloattext_Justify to
TRUE if ALIGN_JUSTIFY, else to FALSE.
MUIA_NFloattext_Justify -- [ISG], BOOL
FUNCTION
Same as Floattext.mui/MUIA_Floattext_Justify.
if TRUE, MUIA_NFloattext_Align will be set to
ALIGN_JUSTIFY, else to ALIGN_LEFT.
MUIA_NFloattext_SkipChars -- [ISG], char *
FUNCTION
Same as NList.mcc/MUIA_NList_SkipChars
and Floattext.mui/MUIA_Floattext_SkipChars.
MUIA_NFloattext_TabSize -- [ISG], LONG
FUNCTION
Same as NList.mcc/MUIA_NList_TabSize
and Floattext.mui/MUIA_Floattext_TabSize.
Tab size defaults to 8.
MUIA_NFloattext_Text -- [ISG], STRPTR
FUNCTION
Same as Floattext.mui/MUIA_Floattext_Text.
String of characters to be displayed as floattext.
This string may contain linefeeds or carriage returns to mark
the end of paragraphs or tab characters for indention.
NFloattext will automatically format the text according
to the width of the NFloattext object. If a word
won't fit into the current line, it will be wrapped.
NFloattext don't copies the string into a private buffer
as Floattext do it, so you need to keep your text in
memory, but it uses less memory.
If you want NFloattext to copy the text, just use
MUIA_Floattext_Text which will do it for compatibility.
Setting MUIA_NFloattext_Text to NULL means to clear
the current text.
Please note that justification and word wrap is a
complicated operation and may take a considerable
amount of time, especially with long texts on slow
machines.
MUIM_NFloattext_GetEntry --
SYNOPSIS
DoMethod(obj,MUIM_NFloattext_GetEntry,LONG pos, APTR *entry);
FUNCTION
Same function as List.mui/MUIM_List_GetEntry.
You'll get pointer to a null terminated string buffer which
is a copy of the asked visible entry.
Unlike with Floattext, the returned string will be valid only
until next MUIM_NFloattext_GetEntry/MUIM_List_GetEntry call
if the entry was word wrapped.
I'll try to make it stay valid when using MUIM_List_GetEntry
only if someone report me some compatibility problem because
doing that will use more memory.
NBalance.mcc/NBalance.mcc NBalance.mcc/MUIA_NBalance_Pointer
This MCC public custom class is derived from the MUI standard balance class which handles the dragging/resizing of vertical and horizontal groups.
In contrast to the standard MUI balance class, however, it adds some features such as displaying a mouse pointer as soon as the mouse is above a dragable NBalance object.
MUIA_NBalance_Pointer -- [ISG.], LONG
INPUTS
MUIV_NBalance_Pointer_Off
MUIV_NBalance_Pointer_Standard (default)
FUNCTION
Allows to set the mouse pointer that should be displayed when
the mouse is found to be above a NBalance object. Per default
a standard horizontal or vertical size pointer is displayed as
soon as the mouse is above a dragable NBalance object.
创建自定义类时，最有可能的情况是扩展现有类的功能，例如提供新外观、处理按键等。Zune 提供了一个接口来实现这些操作。新创建的类可以是应用程序“私有”的，也可以是“公共”的，这样其他应用程序就可以像使用任何现有的（内置或公共自定义）类一样使用它。
要创建自己的自定义类…
在 Aminet 上可用 - 寻找 DisKo
如果你想让你的新自定义类公开可用，例如要包含在 AROS 中，那么有必要注册一个类基地址/类 ID - 以避免与其他开发人员开发的公共自定义类发生冲突。
