The method expects the return of a boolean which should be: true to stop other handlers from being invoked for the event. false to propagate the event further. if event.keyval gtk.keysyms.F11image gtk.imagenewfromstock(gtk.STOCKABOUT, gtk.ICONSIZEDIALOG). is hardwarekeycode for unicode characters? event gtk.gdk.Event(gtk .gdk.KEYPRESS).Heres the answer: Lubuntu has an environment variable set to specify the input method: GTKIMMODULExim.

See Signals on the source widget and Signals on the destination widget for details on the signatures of the callback functions for these signals gtkmain() is another call you will see in every GTK application. When control reaches this point, GTK will sleep waiting for X events (such as button or key presses), timeouts, or file IO notifications to occur. (defun main () (let ((output standard-output)) (within-main-loop (let ((w (make-instance gtk-window)) (da (make-instance drawing-area :width-request 100 :height-request 100))) (connect-signal w " key-press-event" (lambda (widget event) (declare (ignore widget)) (format output " key pressed(Gdk::Event::ALLEVENTSMASK) eb.addevents(Gdk::Event::KEYPRESS MASK).w.showall > Gtk::main. The point of Gtk::EventBox is to enable capturing events on widgets which cant. If you add the EventBox to Window, it is, more or less, non existing. In GTK applications the events are handled automatically in gtkmaindo event() and passed on to the appropriate widgets, so these functions are rarely needed.a mouse button has been released.
