You probably can't focus the frame if you have a window as a child for
the frame since it always gets the focus since it fills the client
area by default so it'd be hard to click on it or at least I couldn't
do it in MSW.

Secondly, you need to either use the window style wxWANTS_CHARS for
wxEVT_CHAR to work or use wxEVT_CHAR_HOOK which is sent before
wxWidgets does any key handling, just be sure to call event:Skip(true)
if you want the wxKeyEvent handled normally.

When you create a menu item; "&Open...\tCtrl+O", wxWidgets will add an
accelerator to intercept Ctrl+O and send the menu event and you won't
get a wxEVT_CHAR for it. Note that wxEVT_CHAR_HOOK will be sent
though.
