Re: [Nuke-users] adding a user knob to a default node

2011-03-18 Thread Ivan Busquets 
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

 Hi,

 I would like to add by default a userKnob (python button) to every
 cornerpin that i create...
 (this button copies the values of the from to the to, which i find very
 practical in everyday compositing)

 is there a way to do that in menu.py ? got any ideas ?

You are not alone in wanting more copy back and forth functions in the
cornerpin node. So if you are not dying to do this yourself this has already
been done by others:

http://www.nukepedia.com/gizmo-downloads/transform/better_cornerpin/

http://www.nukepedia.com/python-scripts/misc/im_cornerpin/

http://www.creativecrash.com/nuke/downloads/gizmos/transform/c/tunedcp2d

I havent tried all of them.

Cheers,
Johan

thank you very much.

i'll try method A

Johan, the code is already written. I'm just looking for a way to include it 
automatically. But thanks for the links, i'll have a look.

Aha. Share on Nukepedia if you can. We can never have too many cornerpins.
That copy functionality should really be there out of the box as well as an
invert button me thinks. But that's the beauty of customization I guess, if
it's not there just build it yourself.
