[pygtk] manipulate image from a gtk.Button

[awalter1]

I have tried your complete example.
A small window is displayed without image in the button.
May be our environment are too different :
unix 11.11 on HPUX
python 2.4.2
gtk+ 2.6.9


>From the time being I'm using this procedure, that seems to work correctly

self.optionButton = gtk.Button(stock=gtk.STOCK_ADD)
SetlabelToButton(self.optionButton,gtk.STOCK_ADD)
...
def SetlabelToButton(button, stock_item=None,label=None):
if (stock_item != None):
	button.set_label(stock_item)
alignment = button.get_children()[0]
  hboxtemp = alignment.get_children()[0]
  image, text = hboxtemp.get_children()
if (label != None):
	text.set_text(label)
else:
	text.set_text('')


regards
