También puedes usar un EventBox
Aqui te dejo el ejemplo con un label, solo cámbialo por una imagen.
Código Python:
Ver original#!/usr/bin/env python
# example eventbox.py
import pygtk
pygtk.require('2.0')
import gtk
class EventBoxExample:
def __init__(self):
window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.set_title("Event Box")
window.connect("destroy", lambda w: gtk.main_quit())
window.set_border_width(10)
# Create an EventBox and add it to our toplevel window
event_box = gtk.EventBox()
window.add(event_box)
event_box.show()
# Create a long label
label = gtk.Label("Mouse over here to quit, quit, quit, quit, quit")
event_box.add(label)
label.show()
# Clip it short.
label.set_size_request(110, 20)
# And bind an action to it
event_box.set_events(gtk.gdk.ENTER_NOTIFY)
event_box.connect("enter_notify_event", lambda w,e: gtk.main_quit())
# More things you need an X window for ...
event_box.realize()
event_box.window.set_cursor(gtk.gdk.Cursor(gtk.gdk.HAND1))
# Set background color to green
event_box.modify_bg(gtk.STATE_NORMAL,
event_box.get_colormap().alloc_color("green"))
window.show()
def main():
gtk.main()
return 0
if __name__ == "__main__":
