You need a "static" variable holding the update value so that
the bar keeps exapanding. Ugly hack:
update_val = 0.10
pbar.set_data ("update_val", update_val)
def updateBar(_button2, pbar=pbar):
update_val = pbar.get_data ("update_val")
pbar.update(update_val)
update_val = update_val + 0.10
pbar.set_data ("update_val", update_val)
