I think the most adequate options would be:
A- Make a onUserCreate callback that adds your custom userKnob every time a
CornerPin node is user-created
or...
B- Override nuke.createNode with your own function, and check in there
whether the node being created is a CornerPin. If it is, then you can
proceed with creating your custom Knob. If not, just call the original
nuke.createNode function.
I would probably choose A for this particular case, but B could be a better
choice if you have other standard nodes that you want to have your custom
version of.
Examples:
A: (using a OnUserCreate callback)
####
def addCornerPinButton():
n = nuke.thisNode()
k = nuke.PyScript_Knob('userKnob', 'userKnob', '')
n.addKnob(k)
nuke.addOnUserCreate(addCornerPinButton, nodeClass = 'CornerPin2D')
####
B: (overriding nuke.createNode() with your own function)
####
def createCustomNodes(nodeClass, knobs = "", inpanel = True):
node = nukeOriginalCreateNode(node = nodeClass, knobs = knobs, inpanel =
inpanel)
if nodeClass == "CornerPin2D":
k = nuke.PyScript_Knob('userKnob', 'userKnob', '')
node.addKnob(k)
return node
nukeOriginalCreateNode = nuke.createNode
nuke.createNode = createCustomNodes
####
Hope that helps.
Cheers,
Ivan
