progressbar widget with glade and python
 

hello there,

can't get this working, when i call the pulse() method nothing happens,

def start_puls(self,widget):
print "start......"
self.voortgang=bn.wTree.get_widget("voortgang")
self.voortgang.pulse()

"voortgang" means "going on" in dutch btw

the function is started when i click a button and should stop when released
