Yep, I ended up using if/elif, too. I posted my sample code in a reply to Ivan,
but here it is again, since I seem to have started more than one email thread
on this… (blush)
def knobChanged(self, knob):
if nuke.thisKnob().name() == 'prefix':
self.do_part_filtering()
self.viewname_filter_mashup()
elif nuke.thisKnob().name() == 'contains':
self.do_part_filtering()
self.viewname_filter_mashup()
elif nuke.thisKnob().name() == 'clear_filters':
self.clear_views_filters()
self.viewname_filter_mashup()
elif nuke.thisKnob().name() == 'config_images':
self.use_part_selection_as_filter()
self.viewname_filter_mashup()
elif nuke.thisKnob().name() == 'exterior_colors':
self.viewname_filter_mashup()
elif nuke.thisKnob().name() == 'interior_colors':
self.viewname_filter_mashup()
elif nuke.thisKnob().name() == 'finishes_colors':
self.viewname_filter_mashup()
elif nuke.thisKnob().name() == 'pick_a_view':
self.active_viewer.setView(self.view_selector_knob.value())
