nuke python : how to update nuke.frame()

[metaclay_vb]

Hi any expert nuke scripterz here? i need help 🙂
i create this code , showing panel and a single button, so when button pressed i want to simply get the current frame number. Here’s the code :

from nukescripts.panels import PythonPanel

class mypanel(PythonPanel):
def __init__(self):
PythonPanel.__init__(self,”test panel”,”uk.co.thefoundry.FramePanel”)
self.curbutton=nuke.PyScript_Knob(“curbutton”,”Get Current Frame”)
self.addKnob(self.curbutton)

def showmsg(self):
f=nuke.frame()
msg = ‘Current frame is ‘ +str(f)
nuke.message(msg)

def knobChanged(self,knob):
if knob== self.curbutton :
self.showmsg()

p=mypanel()
p.show()[/CODE]

The problem is : if i change current frame slider, then press the button. It won’t update untill i restart the panel. So while the panel is still open , it won’t update the nuke.frame() value . i have to ‘kill’ the panel to refresh the value ??

Thanx[CODE]from nukescripts.panels import PythonPanel
