will have to be written that will override ProcessEvent() in order to pass
all events (or any selection of them) to the parent window.
\subsection{Redirection of command events to the window with the focus}
The usual upward search through the window hierarchy for command event
handlers does not always meet an application's requirements. Say you have two
wxTextCtrl windows in a frame, plus a toolbar with Cut, Copy and Paste
buttons. To avoid the need to define event handlers in the frame
and redirect them explicitly to the window with the focus, command events
are sent to the window with the focus first, for
menu and toolbar command and UI update events only. This means that
each window can handle its own commands and UI updates independently. In
fact wxTextCtrl can handle Cut, Copy, Paste, Undo and Redo commands and UI update
requests, so no extra coding is required to support them in your menus and
toolbars.
