The DrawingArea is very rudimentary, I would use a Canvas widget, wherein all these things can be easily done, with Enter and Leave bindings. The Goo canvas is very good, but the old Gnome2::Canvas will work as well. Otherwise, it seems to me that you will need to keep a table of coordinates for all your DrawingArea items, and do some calculations to see whether you are inside or out. 0m, zentara _______________________________________________ gtk-perl-list mailing list gtk-perl-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-perl-list
