Making an element look like a resize grip

[Noam Yorav-Raphael <noamraph gmail com>]

Hello,

I have made a widget that acts as a resize grip (I had to write one by
myself because the resize grip of the statusbar doesn't work on popup
windows for some reason). I used an EventBox for that, and manually
handled button down, up, motion events.

My question is: can I make it look like a resize grip? Is there some
way to take the graphic of it (diagonal lines, or dots) and paint it
on my widget?

Thanks!
Noam
