GUIBaseContext :: doAfterLeave - Pre-event handler before control looses focus

The handler is called, when a focus out event ( GEV_FocusOut ) had been generated.

The handler will be called, when control looses focus ( GEV_FocusOut event). In contrast to doBeforeLeave() , the handler is called bottom-up beginning with the control currently loosing the focus.

The handler should return one of the following return codes:

• -1 (not handled) - the event handler will be removed from the handler list and is not called anymore.
• 1 (stop) - stop calling event handler for the control parent
• 0 (ok) - Event handler terminated successfully.
