I didn't realize there was a way to filter the events. Do I understand correctly that FilterEvent gets the first opportunity to deal with events being raised? Is this relatively new because I was looking for it back in wxPython 2.4 or 2.6 - I think we'll wrap some of this to offer VFP's KeyPreview-like functionality (a bool specifying whether the form or the control with focus gets the first opportunity to deal with keypresses)...
