Chris,
Thanks for the help. When I am done refactoring the code for the
HitTest(), I will apply the same changes to my MouseOver() method
(posted below - This one is much uglier). I also need to make changes to
FloatCanvas._RaiseMouseEvent() but am not really sure what. So far, not
having updated it, the only problem seems to come when panning the
floatcanvas and the mouse goes ontop of another object, which causes the
view to pan back to the starting point.
As far as speed goes I can not yet tell a difference between these
methods and the original color Hitmap.
I will also put together a small demo for the
FloatCanvas.EditableTextBox() but it required some additional methods to
be added to FloatCanvas.ScaledTextBox() but I think I can just overwrite
the ScaledTextBox class with the methods I added so as to comply with
the original FC installation.

##fixme: Can this be cleaned up?

(self.HitDict[EVT_FC_ENTER_OBJECT ] or
self.HitDict[EVT_FC_LEAVE_OBJECT ] )
