@class wxListBox
- A listbox is used to select one or more of a list of strings. The
- strings are displayed in a scrolling box, with the selected string(s)
- marked in reverse video. A listbox can be single selection (if an item
- is selected, the previous selection is removed) or multiple selection
+ A listbox is used to select one or more of a list of strings.
+
+ The strings are displayed in a scrolling box, with the selected string(s)
+ marked in reverse video. A listbox can be single selection (if an item is
+ selected, the previous selection is removed) or multiple selection
(clicking an item toggles the item on or off independently of other
selections).
- List box elements are numbered from zero. Their number may be limited
- under some platforms.
+ List box elements are numbered from zero and while the maximal number of
+ elements is unlimited, it is usually better to use a virtual control, not
+ requiring to add all the items to it at once, such as wxDataViewCtrl or
+ wxListCtrl with @c wxLC_VIRTUAL style, once more than a few hundreds items
+ need to be displayed because this control is not optimized, neither from
+ performance nor from user interface point of view, for large number of
+ items.
- A listbox callback gets an event wxEVT_COMMAND_LISTBOX_SELECTED for
- single clicks, and wxEVT_COMMAND_LISTBOX_DOUBLECLICKED for double clicks.
+ Notice that currently @c TAB characters in list box items text are not
+ handled consistently under all platforms, so they should be replaced by
+ spaces to display strings properly everywhere. The list box doesn't
+ support any other control characters at all.
