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 @c wxEVT_COMMAND_LISTBOX_SELECTED for
- single clicks, and @c 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.
