I've always used Widget.ButtonPressEvent for this sort of thing; you
want to do your thing before GTK's default handers get to it.

[Widget.ButtonReleaseEvent is when you let go of the mouse, not when you
click it. I imagine you knew that, but you can sometimes fake yourself
our with what the right behaviour to hook into is. Same goes for key
presses; I work with Widget.KeyPressEvent most of the time, only rarely
does one need Widget.KeyReleaseEvent]

Anyway, give it a try and see how you go.
