EVENT_FUNCS [message #16126]

Can anyone possibly describe exactly how event _funcs work.

The reason I am interested is that I would quite like my DERAgrWindow
(direct graphics version of IDLgrWindow), to handle expose events so
that it can protect its colours automatically under an 8 bit display,
if you ask it to.

The problem comes if the user wants to be getting their own events
from the draw widget. I think that I might be able to use event_func
to intercept the ones I want, do something, and then send the events
back up the event train.

Can anyone describe how event_funcs work and what problems there are
with them.

Cheers,
Phil
