This is one of the reasons it’s good to keep references to your panel’s knobs
on the panel instance.
def knobChanged(self, knob):
if knob is self.a_knob:
something = self.a_knob.value()
elif knob is self.b_knob:
print 'that was the b knob'

Subject: [Nuke-python] knobChanged question...
Hi,
This is probably a very elementary question, but I can't quite wrap my head
around it…
I have a Python_Panel with four knobs on it: three Enumeration_Pulldown knobs
and a PyScript_Knob. I have added them all to a knobChanged method. I am using
something like this for my checking:
def knobChanged(self, knob):
if a_knob:
set_something = a_knob.value()
if b_knob:
set_something_else = b_knob.value()
if c_knob:
set_another_thing = c_knob.value()
if d_knob:
run_a_method()
You will probably notice that each time a knob is changed, all of the
statements are executed, including the run_a_function(). I'm sure this is from
"Programming 101", but how do I isolate the knob changed events, so that *only*
the one that has been changed is executed…?
Thanks for any help!
Rich
