I have a Glade project main app window with a toolbar and 4
'drawingarea’s, into which I draw some test images using Cairo.
After anywhere between 50 and 100 drawingarea updates I get the
following message when clicking on a toolbar button.
cairo_test_2.rb:147: warning: GRClosure invoking callback: already
Before the 50-100 drawingarea updates, the callback works fine.
Could anyone possibly tell me, or offer an opinion as to why the
callback is getting destroyed?
All I am doing is updating the drawing areas and clicking on a toolbar
I use Ubuntu Linux, Gnome2, Glade2 and Cairo of course.
