[pygtk] Popup menu for gnome applets.

[Pedro Dalcin]

I'm trying to create an applet that has a simple popup menu, but my menu
wont pop when I click on the button with the left mouse button, only with
the right mouse button! I really cant figure out what the problem is.... If
any one could help me would be great. Here is my code:
#!/usr/bin/env python

import pygtk
import sys
pygtk.require('2.0')

import gnomeapplet
import gtk

num =3D 0

def factory(applet, iid):

        button =3D gtk.Button()

        button.set_relief(gtk.RELIEF_NONE)
        button.set_label("ExampleButton")
        button.connect("button_press_event", showMenu, applet)
#       button.connect("clicked", on_button_clicked) // im not using
"on_button_clicked right now
        applet.add(button)
        applet.show_all()
        return True


def on_button_clicked(button, *args):
#       button.emit_stop_by_name("button_press_event")
#       create_menu(applet)

#     this is only for change the buttons image
        global num
        if (num%2=3D=3D0):
                image =3D gtk.Image()
                image.set_from_file
("/usr/share/icons/gnome/48x48/devices/gnome-dev-floppy-red.png")
                button.set_image(image)
                button.set_label("")
        else:
                image =3D gtk.Image()
                image.set_from_file
("/usr/share/icons/gnome/48x48/devices/gnome-dev-floppy-green.png")
                button.set_image(image)
