Sending this one to the list for posterity, since I'm currently talking to
you on IRC.
In order to hide the knob on the container node, you have to call
.setVisible(False) on the Link_Knob object itself. The tricky part about
this is that trying to grab a Link_Knob using <node>.knob('render_views') or
the knob name subscription syntax will cause the Link_Knob to resolve to its
target.
Instead, use <node>.knobs()['render_views']. This gets you the "pointer"
knob, which can be shown/hidden separately from the target, and since that's
what actually "exists" on your Group, the visibility behavior will behave
correctly.

Subject: [Nuke-python] Hiding/showing linked knobs in gizmos
Hi,
I've got a Render Gizmo here that has a disabled Write node inside it.
I'm using this Write node to access certain internal functionalities of
the Write node, including creating link knobs for both Format and
ColourSpace.
The other knob that I'm linking is Views. However, with this knob, I
want to hide/show it based on other knobs in my Gizmo.
I've called my linked knob "render_views":
addUserKnob {41 render_views l Views T Write1.views}
I don't seem to be able to hide this knob, by either hiding the knob on
my Gizmo or by hiding the knob it's linked to.
I've tried both of the following methods:
n['render_views'].setVisible(False)
and
with n:
w = nuke.toNode("Write1")
w['views'].setVisible(False)
Any idea how I can do this?
I did try adding a MultiView_Knob to my node, but this didn't serialize
out properly - it ended up in the gizmo as:
addUserKnob {0 render_views l Views}
Any ideas?
Cheers
Hugh
