ss_before_knob_changed v1.0

Sometimes we write callbacks that have to do a lot of work and for that reason take some time to evaluate.

To prevent this from happening everytime you select a node or move it and to avoid writing fiter statements in your code all over the place you can use this nifty decorator on top of your callback definition.

 

 

#Usage:

 

import time # Only for this example

from before_knob_changed_decorator import ss_before_knob_changed

 

# Sluggish moronic callback

@ss_before_knob_changed  # Try it with and without the decorator to see the difference

def my_callback():

    time.sleep(0.2)

 

# Get node to apply callback to

node = nuke.selectedNode()

 

# Apply custom callback.

node.knob('knobChanged').setValue('my_callback()')
