or this ugly hack ;o)
i=1
while(i<the_highest_num_label):
if(self.hasattr('label' + str(i))):
label = self.getattr('label' + str(i))
label.setText('')
The node traversal is probably a better solution though.. If you do the
traversal inside __init__ on your dialog and store the resultant set of
labels, you would only have to traverse the nodes once and you don't have to
hard code the list of labels into every dialog.
