Anybody know how to make GTk+ generate a signal on a right-mouse
click on a button (or a button-bar)? "clicked" seems to only be
generated by a left-click. Same for "pressed" and "released".
Better, anybody do context-sensitive popup menus w/ guile-gtk?
Thanks,
Greg

Try the "button_press_event" signal, like so
(use-modules (gtk gtk)
(gtk gdk))
(let ((w (gtk-window-new 'toplevel))
(b (gtk-button-new-with-label "Click Me Right!")))
(gtk-container-add w b)
(gtk-signal-connect b "button_press_event"
(lambda (ev)
(cond
((= (gdk-event-button ev) 3)
(display "Yes!\n")
#t)
(else
#f))))
(gtk-widget-show-all w)
(gtk-standalone-main w))

For a context-sensitive popup menu out of such an event, build the menu in
the event handler, and use gtk-menu-popup. In this code, I put the actual
gtk-signal-connect in C, which calls out to guile on selected events and
passes along a context object. The menu actions are specific to my
program, but you get the idea I'm sure.
I've done this for a drawing_area - does the menu pop up in the
correct-looking place when attached to a button?
(wavepanel-bind-mouse 3 ; calls proc on indicated button-press event
(lambda (wp event)
(let ((menu (gtk-menu-new)))
(gtk-widget-show menu)
(add-menuitem menu "Zoom Cursors" x-zoom-cursors!)
(add-menuitem menu "Zoom Area..." x-zoom-area!)
(add-menuitem menu "Zoom Full" x-zoom-full!)
(case (wavepanel-type wp)
((0) (add-menuitem menu "Set type jge"
(lambda () (set-wavepanel-type! wp 1))))
((1) (add-menuitem menu "Set type std"
(lambda () (set-wavepanel-type! wp 0)))))
(gtk-menu-popup menu #f #f
(gdk-event-button event)
(gdk-event-time event)))))
; add-menuitem is a little helper to make menu and menubar creation
; a bit more readable.
(define-public (add-menuitem parent label proc)
(let ((item (if label
(gtk-menu-item-new-with-label label)
(gtk-menu-item-new))))
(gtk-widget-show item)
(if proc
(gtk-signal-connect item "activate" proc))
(cond ((gtk-menu? parent) (gtk-menu-append parent item))
((gtk-menu-bar? parent) (gtk-menu-bar-append parent item)))
item))
