Node settings Lock

[metaclay]

Hi metalcay This is really smart. But why dont you write If then else for this. If selected node is already locked then unlock it...... like this.

I'm trying to creating Lock-Unlock python buttons. The problem is while run the lock function it also lock the Unlock button too. Trying to figure out solution for that.

There's no ideal way to check whether the node is LOCKED or NOT. if the node is locked means => if all knobs are locked or if first knob is locked? it depends on RULES , what condition u want to make it to be "the node is locked". The script is unlimited , it's just u who need to create the proper 'rules' :-). For this simple toggle u don't need if/then/else , coz it can be solved with single NOT expression. This is the function if u want to check only the first knob is locked or not :

def locktoggle(nodes):
  for node in nodes :
    state=not node.allKnobs()[0].enabled()
    allknobs=node.allKnobs()
    for knob in allknobs:
       knob.setEnabled(state)
    nuke.toNode(node.name()).setSelected(False)
    nuke.toNode(node.name()).setSelected(True)


nodes=nuke.selectedNodes()
locktoggle(nodes)

btw, u can create a right-click menu for every knob, but the problem is : after lock the knob, it become greyed out so there's no way u can do 'right-click' again.,.. this prevents u from unlocking the knob. This is not a bug, i prefer the term 'imperfection'. Also, when it's being greyed out, i can't cmd+drag the knob to create link. This is annoying.

Try this , i think it's better than if/then/else :-)

set cut_paste_input [stack 0]
version 6.3 v4
push $cut_paste_input
Transform {
 center {960 540}
 name Transform6
 label "\[python -exec \{\nthis=nuke.thisNode()\nx=not this.knob('lockz').value()\nallknobs=this.allKnobs()\nfor knob in allknobs:\n   if knob.name() != 'lockz':\n      knob.setEnabled(x) \n\} \n]"
 selected true
 xpos -377
 ypos -113
 addUserKnob {20 User}
 addUserKnob {6 lockz l "lock me please" +STARTLINE}
}

in the user tab, there's lock control.

Here is the simple solution for lock and unlock node settings. I made some changes on 'metalcays' code and assigned shortcut keys. temp solution for lock the node settings.

for lock - ctrl+l
for unlock - shift+l

enjoy....

actually you can just create single function then pass the 'state' argument contain value of True or False. so delete the unlockNode.py and modify lockNode.py :edit the 'def lockNode()' part as follow :

import nuke
def lockknob(nodes,state):
  for node in nodes :    
      allknobs=node.allKnobs()
      for knob in allknobs: 
          knob.setEnabled(state)
      nuke.toNode(node.name()).setSelected(False)
      nuke.toNode(node.name()).setSelected(True)e)

def lockNode(state):
  a=nuke.selectedNodes()
  lockknob(a,not state)

then for menu:

import lockNode
menuBar.addCommand('Edit/Node/lockNode', 'lockNode.lockNode(True)', 'ctrl+l')
menuBar.addCommand('Edit/Node/unlockNode', 'lockNode.lockNode(False)', 'shift+l')

i use 'not state' insted of 'state' . U can use 'state' also if u want and inverse the logic. But i'm doing this way to make the function() readable , means :
--> lockNode(TRUE) is like saying : yes, TRUE.. i want to Lock the Node.
--> lockNode(FALSE) is like saying : no/FALSE... do not lock the Node.
