Wow, that's perfect. I can definitely imagine that it might do some
undesired damage to the layout, however, the example works perfectly in my
situation.
For posterity, I'll explain it in more detail. Nuke's offers a command to
use a QWidget as a panel (PythonPanel) in the UI. This is done with
nukescripts.panels.registerWidgetAsPanel('WidgetName','Label
Name','uniqueID'). The parent is not available in the constructor, but it
should be available when the widget is finally shown. So by re-implementing
the showEvent on the QWidget subclass, there is finally access to parent
widget, and therefore the margins. It just so happens, that there are many
parent widgets adding these annoying margins.
I consider this a hacky solution, but it's not overly complicated. I like
it. Thanks for the help Frank.
I might try to do some more introspection to see if there is any way to
identify and adjust only the relevant ancestral perpetrators.
Cheers,
Jesse
