Yeah, I don't why but it's not refreshing...
try this simple callback (make sure the pulldown name is 'menu' and the
backdrop is 'backdrop')
def changeLabel():
if nuke.thisKnob().name() == 'menu':
nuke.toNode('backdrop').knob('label').setValue(nuke.thisKnob().value())
nuke.callbacks.addKnobChanged(changeLabel, args=(), kwargs={}, nodeClass =
'Root' )
cheers,
