Mouse wheel events

[Tom Trebisky <tom mmto org>]

Hello,

I have a GTK 2 application I have been developing that I would like
to have use mouse wheel events.  I have a mouse event handler that
gets left and right button events just fine, (being connected to the
button release event).  Naturally, it doesn't get a thing when I
rotate the center wheel on the mouse.  Can anyone tell me what
to do, or direct me to appropriate documentation?

Thanks!
