I need to amend my email and correct some erroneous information…
—— First of all, setting the knob value to a string, like ‘foobar’, *does*
work!
...Not sure what I was doing that made the test not work before, but it does
now…. ~(8^P
—— Secondly, what does *not* work is setting the knob value to the result of a
function. What I am actually trying to do is set the knob’s initial value to
nuke.activeViewer().view(). The result is a string, but when recalling the Nuke
script with a registered panel - the panel does not show. It does not matter if
I set the value beforehand, either. I.e., if I do something like this:
self.current_view = nuke.activeViewer().view()
…then…
self.partStartsWith_knob.setValue(self.current_view)
—— That will work fine when initially creating the tabbed panel - but fails to
show anything when the script is saved and reloaded.
—— So, here’s a better test that shows the problem:
import nuke
import nukescripts
class testpanel( nukescripts.PythonPanel ):
def __init__(self):
# Get the view name and assign it...
self.current_view = nuke.activeViewer().view()
nukescripts.PythonPanel.__init__(self, 'View Selector',
'com.richbobo.testpanel')
self.partStartsWith_knob = nuke.String_Knob('startswith', 'View Name -
Starts With :')
self.addKnob(self.partStartsWith_knob)
# Set the initial view name value to the knob...
self.partStartsWith_knob.setValue(self.current_view)
—— Sorry for the confusion!
