Help to complete this.....

[sathees]

Hi friends, Currently i'm learning python scripting. I got on idea to create a tool for my convenience.

idea is.... extracting a single frame using "FrameHold" function. I created below .py file with my knowledge. Cant make it work what i expect. My panel result (what ever value i given as a input ) will print on to the "FrameHold" "first_frame" field.

some one please help me to complete this script.

    ef.addSingleLineInput("frame:","")
    ef.addButton("cancel")
    ef.addButton("ok")
    result = ef.show()
    
    if result == 1:
        print "ok"
    
    else:
        print "canceled"
    
def singleFrame():
    fh = nuke.createNode("FrameHold")
    fh.setName('singleFrame')
    
singleFrame()
    
def mainFunc():
    extractFrame()
mainFunc()

import nuke
## creating panel
def extractFrame():
ef = nuke.Panel("extractFrame", 20)
ef.addSingleLineInput("which frame you want to extract:","")

## create framehold and modify
fh = nuke.createNode("FrameHold")
fh.setName("singleFrame")
fh['first_frame'].setValue(int(result))
fh['postage_stamp'].setValue(1)


Manu py:
import extractFrame
n = nuke.toolbar('Nodes')
menu.addCommand('Edit/extractFrame', 'extractFrame.extractFrame()', "F2")


( you can change the shortcut from "F2" to what ever you want )
