[pygtk] manipulate image from a gtk.Button

[awalter1]

the button.set_image (newImage) has no effect !

"If you can't use the set_image method, you'll have to keep a reference to
the image you want to remove, remove it" : the initial question was how to
remove the image from a gtk.Button. and a button.remove(image) generates an
error.

Regards
