-    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

+    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.
