Re: Events and Signals



Hi

I tryed to change event.keyval to GDK_Left(left key arrow) to test it. But
it doesn´t work.
My question is if is possible to sent key events (keys arrows) to move on a
GtkCList using gtk_event_put()?
Remember that I recieve network event and I´d like to move on GtkCList and
select items on it.

Thanks a lot and regards
