Overwrite mode in wxTextCtrl

[GDR!]

Hi wxHackers,

Is it somehow possible to initialize a wxTextCtrl to work in overwrite mode (just like you pressed Insert on your keyboard before entering text)? 

I tried doing it by EmulateKeyPress(), but - apart from the fact that this is far from being an elegant solution - it doesn't work, but it just might be me crafting invalid wxKeyEvent.
