+wxWindow is the base class for all windows. Any children of the window will be deleted
+automatically by the destructor before the window itself is deleted.
+
+Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
+help text. These must not be called by a user program and are documented only for illustration.
+On several platforms, only a few of these handlers are actually written (they are not always
+needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
+the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
+platform can implement its native behaviour or just ignore the event if nothing needs to be
+done.
