Re: Is it possible to attach signalhandler to a GdkWindow?

["Donna S. Martin" <donna omartin com>]

A GtkWindow is a decendant of a GtkObject, so it
works with a GtkWindow...but a GdkWindow is a totally
different thing, as it's a simple window id, not a widget.
Did you really create just a GdkWindow?  If you do,
you're working at just the GDK level, which seems fine
when you're doing the drawing as those are all
GDK calls, but you're losing all the widget interactions
because they are at the GTK level (and you don't get
the signal_connect()!).   Do you do the
gtk_init() and all?  If so, I think using a drawing area
is actually quite simple, and then the drawing you're doing
stays the same.  You create a drawing area widget of the
same size as  your GdkWindow, and you just use it's
window id in your drawing functions.

Basically, I think you should look at the scribble example in the
tutorial, and see if that helps.....
