Clickable Icon in Python GTK
Question: Does anyone know how to create a custom button with custom icon in PyGTK? I
would like to make a program in python GTK that works similar to a settings
menu or control panel. I know PyGTK has stock buttons like cancel, exit, and
ok; but I'm unable to change the labels or icons of those buttons.


Answer: You can put a button on the screen, and put any image in it.

    import pygtk
    import gtk
    
    IMAGE_FILE = "/put/an/imagename here"
    
    class MainWindow(gtk.Window):
        def __init__(self, debug = None):
            gtk.Window.__init__(self)
            self.connect("delete-event", self.on_delete_event)
    
            btn = gtk.Button()
            img = gtk.Image()
            img.set_from_file(IMAGE_FILE)
            btn.set_image(img)
    
            self.add(btn)
            self.show_all()
    
        def on_delete_event(self, win, data):
            gtk.main_quit()
    
        def run(self):
            gtk.mainloop()
    
    def main():
        w = MainWindow()
        w.run()
        return 0
    
    if __name__ == '__main__':
        main()
    

The image can be of many formats, even SVG (vector graphics), PNG, etc.
