Instead of using a hidden checkbox, you should be able to use
onUserCreate, which shuold only be triggered when the node is created
initially (not when it is loaded from an nk file or pasted etc).

Hi Ron,
Set the onCreate knob with a script that checks for a checkbox
value and if none gets the input width and height and sets the
knob you want and then toggles that checkbox to prevent this
callback from being "evaluated" again.
Something like this:
k = """node = nuke.thisNode()
w = node.width()*0.5
h = node.height()*0.5
if not node.knob('set').value():
node.knob('pos').setValue((w,h))
node.knob('set').setValue(True)"""
nuke.selectedNode().knob('onCreate').setValue(k)
Where the knob "set" is a checkbox knob that is hidden. I believe
this is what I've done in the past and it used to work.
Hope it helps.
Merry Christmas!
Cheers,
Diogo

Yeah, that's a callback. If the callback is really
simple (one simple line), than maybe. Otherwise, not
possible.
Thanks,

Is there some onCreate function you could use? If
so, you could set the expressions when it's created.

Hi all,
Merry Christmas everyone who celebrates it. You
keep on enjoying your holiday and disregard this
email.
Hi everyone else,
I'm making a little Gizmo and I want the default
2D position knob to default at the center of
whatever resolution there is when the gizmo is
created. If, before wrapping it all up as a
Gizmo, I type width/2 in the input field of the
position knob, the expression evaluates and I'm
left with just a value, which won't change once
the Group is a Gizmo. If I add this as an
expression, I get left with an expression. Is
there a way to make it dynamic, but without
leaving the expression there?
And for what I'm doing, callbacks aren't really
an option.
Cheers,
Ron Ganbar
