RE: [gtk-list] Need advice on key_press_event.

Hi,

You should call gtk_widget_grab_focus (<canvas widget>) to lead all default events to that widget (I presume you have a GtkDrawingArea as canvas). Note that you have to do that after you realized the widget and it's parent widgets (let's say after a gtk_widget_show_all () ).
This works fine for my widget (DiaCanvas at http://web.inter.nl.net/hcc/klem/diacanvas.html).

regards,

Arjan
