any documents about signals and events?

[Randy <randyqiuxy hotmail com>]

Hi list,
I'm new here.I'm learning to program with GTK+ via the on-line
tutorial.But I find the info about signals and events are not enough to
being understood.
What's mean by each event and when are they triggered?
For instance,what is the "configure-event"?
I think there is some info which could help me know them more clearly.
Any clue?
Thanks for any suggestion!

Best regards,
Randy
