Yes, I figured as much, but then I realised that there didn't exist any 
methods to actually draw in it. It was kind of a bummer. :-)

Yes, that's what I used. It works great by the way, even though I would 
like some more control as to on which handler class the callbacks are 
called. Maybe there is, if so I'd love to know about it. I had to read 
the source and try to figure out how it was weant to work.

Good work still. :-)

Good luck! I'll be waiting for it. :-)

The test application I intended to write while learning java-gnome was a 
small paint program. And for that you need graphics methods. :-)
