+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.

\wxheading{Remarks}
-This event is only generated under Windows.
+Under non-Windows platforms, this event is simulated (simply generated just before the

+The default background colour under GTK is grey.
To intercept this event, use the EVT\_ERASE\_BACKGROUND macro in an event table definition.
Use the EVT\_PAINT macro in an event table definition to intercept paint events.
-In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
+Note that In a paint event handler, the application must {\it always} create a \helpref{wxPaintDC}{wxpaintdc} object,
