It's important to know that MUI makes a difference
between a list and a listview. A list is just a
collection of some entries and is part of a listview,
which attaches a scrollbar and input handling to
the list.
During object creation time, you have to be careful
not specifying listview tags for the list object
or list tags for the listview object, both versions
won't work. Once the objects are setup, you can
of course talk to the listview as if it was the
list directly.
Listview.mui/MUIA_Listview_ClickColumn
NAME
MUIA_Listview_ClickColumn -- (V7 ) [..G], LONG
FUNCTION
When using a multi column list, this attribute contains the number of
the column where the user clicked.
SEE ALSO
MUIA_Listview_DefClickColumn
Listview.mui/MUIA_Listview_DefClickColumn
NAME
MUIA_Listview_DefClickColumn -- (V7 ) [ISG], LONG
FUNCTION
When the listview is controlled with the keyboard and the user
presses RETURN, the value given here will be used as default
for MUIA_Listview_ClickColumn.
SEE ALSO
MUIA_Listview_ClickColumn
Listview.mui/MUIA_Listview_DoubleClick
NAME
MUIA_Listview_DoubleClick -- (V4 ) [I.G], BOOL
FUNCTION
This attribute is set to TRUE whenever the user
double clicks on an entry in the list.
SEE ALSO
MUIA_Listview_SelectChange
Listview.mui/MUIA_Listview_DragType
NAME
MUIA_Listview_DragType -- (V11) [ISG], LONG
SPECIAL INPUTS
MUIV_Listview_DragType_None
MUIV_Listview_DragType_Immediate
FUNCTION
If you want the user to be able to drag items out of
your list, you must set this for the listview class.
Currently, only one drag type is defined.
Listview.mui/MUIA_Listview_Input
NAME
MUIA_Listview_Input -- (V4 ) [I..], BOOL
FUNCTION
Setting this to FALSE will result in a read only
list view. Defaults to TRUE.
SEE ALSO
MUIA_Listview_MultiSelect
Listview.mui/MUIA_Listview_List
NAME
MUIA_Listview_List -- (V4 ) [I.G], Object *
FUNCTION
Every listview needs a list object as child.
Specify it here.
As every other child, it will get disposes when
its parent object is disposed.
EXAMPLE
ListviewObject,
MUIA_Listview_Input, FALSE,
MUIA_Listview_List , ListObject,
ReadListFrame,
MUIA_List_Format , ",,",
End,
End;

MUIA_Listview_Input
Listview.mui/MUIA_Listview_MultiSelect
NAME
MUIA_Listview_MultiSelect -- (V7 ) [I..], LONG
SPECIAL INPUTS
MUIV_Listview_MultiSelect_None
MUIV_Listview_MultiSelect_Default
MUIV_Listview_MultiSelect_Shifted
MUIV_Listview_MultiSelect_Always
FUNCTION
Four possibilities exist for a listviews multi select
capabilities:
MUIV_Listview_MultiSelect_None:
The listview cannot multiselect at all.
MUIV_Listview_MultiSelect_Default:
The multi select type (with or without shift) depends on
the users preferences setting.
MUIV_Listview_MultiSelect_Shifted:
Overrides the users prefs, multi selecting only together
with shift key.
MUIV_Listview_MultiSelect_Always:
Overrides the users prefs, multi selecting without shift key.
Please do *not* override the users prefs unless you have a
good reason!

Listview.mui/MUIA_Listview_ScrollerPos
NAME
MUIA_Listview_ScrollerPos -- (V10) [I..], BOOL
SPECIAL INPUTS
MUIV_Listview_ScrollerPos_Default
MUIV_Listview_ScrollerPos_Left
MUIV_Listview_ScrollerPos_Right
MUIV_Listview_ScrollerPos_None
FUNCTION
Specifies the position of a listviews scrollbar.
Don't use this tag unless it's absolutely required!
If you specify MUIV_Listview_ScrollerPos_None, your listview
wont get a scroller at all and look much like a list object
alone. However, listviews without scroller are still more
powerful than list objects as they feature e.g. drag&drop
possibilities.
Creating listviews without a scrollbar makes sense if you
want to have the scrollbar somewhere else, e.g. outside
of a horizontal virtual group where the listview resides.
This technique allows the creation of horizontally
scrollable listviews.
When you create the scrollbar on your own, connect it
to the list object (not listview object!) like this:
DoMethod(sbar,MUIM_Notify,MUIA_Prop_First ,MUIV_EveryTime,
list,3,MUIM_Set,MUIA_List_TopPixel,MUIV_TriggerValue);
DoMethod(list,MUIM_Notify,MUIA_List_TotalPixel ,MUIV_EveryTime,
sbar,3,MUIM_Set,MUIA_Prop_Entries ,MUIV_TriggerValue);
DoMethod(list,MUIM_Notify,MUIA_List_VisiblePixel,MUIV_EveryTime,
sbar,3,MUIM_Set,MUIA_Prop_Visible ,MUIV_TriggerValue);
DoMethod(list,MUIM_Notify,MUIA_List_TopPixel ,MUIV_EveryTime,
sbar,3,MUIM_Set,MUIA_Prop_First ,MUIV_TriggerValue);
Listview.mui/MUIA_Listview_SelectChange
NAME
MUIA_Listview_SelectChange -- (V4 ) [..G], BOOL
FUNCTION
This attribute is set to TRUE whenever the selection state
of one or more items in the list is changing. You can
use this e.g. if you want to display the number of
selected items in a status line.
