     It checks the type of the window and uses an appropriate type for it.
     For example, wxButton and wxTextCtrl transfer data to and from a
     wxString variable; wxListBox uses a wxArrayInt; wxCheckBox uses a boolean.
 
+    @since 3.2.5
+    A wxLB_SINGLE wxListBox can also use an int.  wxColourPickerCtrl support.
+    A 3-state wxCheckBox can use wxCheckBoxState.
