-    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.
