"Floating" shapes on image

["Johan Kohler" <kohlerj ukzn ac za>]

Hi,
I wnat to add shapes (rectangles, polygons) to an image that I'm  
displaying in a Gtk::Image .  The shapes should be "floating" on top of  
the image so that they can be moved or resized with the mouse.  I suppose  
a class that redraws itself at different locations is a good start?  But  
how would I capture mouse events on such an object though?  Can I simply  
use _clicked()? I suppose its sort of like a canvas effect - should I use  
Gnome Canvas instead?

Thanks...
Johan
