$event->state gives the "GdkModifierType" keys (per Gtk2::Gdk::Event). > 3. I also want the user to be able to select multiple rectangles by > dragging the mouse across a portion of the DrawingArea. I made a Gtk2::Ex::Lasso (on cpan). It's "xor" based so depends on a mostly single colour background but the drawing is fast. It's basically button-press to start then motion-notify for the drag and button-release to end. But you might want to listen for Escape key or something to abort a selection. > 4.

That's an artifact of the x11 pixel rule "on the boundary left or above". It comes from an unfilled rectangle being a 1-wide line but filled being a 0-wide boundary ... more or less. > 7.

I think it's supposed to work. $tooltip->set_text with whatever new string you want to show. Post a failing program if not. You might prefer to show something in a statusbar as the mouse moves. (In which case motion-notify-event and enter,leave.) > 'pointer-motion-hint-mask', Remember to $window->get_pointer() if using that. Otherwise you don't get any more motion events. -- At the Sydney Olympic stadium workmen shortened the 100m track to 94m to make room for a communications pit. It was only noticed before the Games when an under-16 schoolboys meet broke the Commonwealth record. _______________________________________________ gtk-perl-list mailing list gtk-perl-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-perl-list
