Item destroy signal

["Till Harbaum / Lists" <lists harbaum org>]

Hi,

i am changing an application from gnomecanvas to goocanvas. So far everything
went smooth, but now i am having trouble:

In gnomecanvas the items were children of gtkwidget. Upon destruction if e.g.
the parent group was destroyed the "destroy" signal was being sent to all
items of that group.

I am unable to find a matching mechanism in goocanvas. How can i signal an
GooCanvasItem that it's being destroyed? E.g. if  goo_canvas_item_remove is
called for that item. 

Regards, 
   Till
