here is a example of what i'm doing
import nuke
import nukescripts
import time
class ShapePanel( nukescripts.PythonPanel ):
def __init__( self):
nukescripts.PythonPanel.__init__( self, 'BoolKnobs' )
self.update = nuke.PyScript_Knob('update', 'Update')
self.addKnob(self.update)
self.nodes_match = []
self.bool_knobs = []
self.clear_bool_knobs()
self.node_name = ""
def create_bool_knobs(self):
m = time.clock()
del self.bool_knobs[:]
print "clear list time: ",time.clock()-m
print "list length ", len(self.nodes_match)
for i in range(0,100):
k = nuke.Boolean_Knob("a_knob",str(i),0)
k.setFlag(nuke.STARTLINE)
self.bool_knobs.append(k)
for a in self.bool_knobs:
ma = time.clock()
self.addKnob(a)
print "added knob time: ",time.clock()-ma
print "total knob time: ",time.clock()-m
def knobChanged(self, knob):
if knob.name() == "showPannel" :
self.clear_bool_knobs()
elif knob is self.update:
self.clear_bool_knobs()
def clear_bool_knobs(self):
for a in range(len(self.bool_knobs)):
self.removeKnob(self.bool_knobs[a])
self.create_bool_knobs()
p = ShapePanel()
if p.show():
try:
print "changed some stuff"
except:
print "no matching nodes found"
