Yes. Nice! That helps a lot; Thank you, Thank you :)

Otherwise, a fairly generic way to do this is to again have generic callback functions that call commands that are actually attached to the node. So you could stick your callback code in a hidden PyScript knob and then have the generic callbacks look for appropriately-named knobs, and if it finds them, exec their .command() return string. This means you only have to set up one additional callback structure that will work for as many extra nodes/classes as you want to add, but will allow you to attach the actual callback code to the node itself. Hope this makes sense. -Nathan From: Ken Boreham <mailto:[email protected]> Sent: Tuesday, June 07, 2011 10:05 AM To: Nuke Python discussion <mailto:[email protected]> Subject: RE: [Nuke-python] Callback for Group Ah, so with Gizmo I would filter with nodeClass=’NameOfGizmo’? The groups solution works nicely-thanks. In either case is there any way to embed the callback into the group/gizmo?

However, being more a fan of Groups myself, I’ve previously worked around this by adding a hidden “class” knob to any group I want to run callbacks on, and then adding a generic Group callback function that uses the value of that class knob to get and call an appropriate callback function from a “group callbacks” module. -Nathan From: Ken Boreham <mailto:[email protected]> Sent: Tuesday, June 07, 2011 8:50 AM To: [email protected] Subject: [Nuke-python] Callback for Group I’d like to make a knob changed callback for a group/gizmo that I’m working on. - I can make a global callback and filter it to the nodeClass=’Group’ but then it runs on any Group. How do you safely handle this? - Creating a global callback requires extra code. How would I distribute this? Would it require an extra python script file to be loaded with the group?
