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)...
