hiya,
you've got the right knob name, but you have to use
setExpression instead, like:
w = nuke.createNode("Write")
w.knob('disable').setExpression('frame<10')
hope that's what you're after

Hi,
In Python, how do I set an expression on the disable knob of a node?
If I do something like this…
w = nuke.createNode("Write")
w.knob('disable').setValue('frame<10')
...the Write node is created as "disabled" with an X through
it. What I want, of course, is the string added as a
conditional expression for the disable knob.
I can't figure out how to address the expression field.
Usually, I can hover over a field and get a popup with the
name, but not with the expression field input…
Thanks for any help,
Rich
