[pygtk] button-press-event on a TreeViewColumn Header?

[saeed]

Tim Evans: But it doesn't work for me! The "button" receives neither
"button-press-event" or "pressed" or "clicked". I receives only an
expose-event when resizing column.

def show_event(widget, event):
  print type(widget), event.type.value_name
button.connect('event', show_event)
