Thank you for the answer Ean.
In fact "nuke.frame(nuke.frame() + 1)" was an example to force the
autolabel callback, but this line will change the current frame in the
viewer and I don´t want it.
The problem seems to be solved doing this:
def knobChangedCallback():
if nuke.thisKnob().name() == 'inputChange':
nuke.thisNode()['autolabel'].setValue(None) # this seems to
properly trigger the autolabel callback
nuke.addKnobChanged(knobChangedCallback)
def autolabelCallback():
input = nuke.thisNode().input(0)
if input.Class() == 'Read':
return 'XXXX'
else:
return 'YYYY'
nuke.addAutolabel(autolabelCallback)
Thanks again Ean.
