I am using the scale widget in Tkinter and after I scale the value from 0 I would like the value to  go back to 0 once the slider loses focus. (This would be the CameraPan variable)

Example: I slide the scale to 45 and when I release the mouse the scale jumps back to 0.

My question is how can I do that? Thanks for your help.

#! /usr/bin/env python

from Tkinter import *
master = Tk()


def camera_pan(camera_pan_value):
    print(camera_pan_value)

CameraPan=0

CameraPan180 = Scale(master, from_=-90, to=90,tickinterval=15,label="Camera Pan (left right)",resolution=1,orient=HORIZONTAL,length=350,width=25,command=camera_pan)
CameraPan180.set(CameraPan)
CameraPan180.pack()

mainloop()

create two variables cpmin = -90
cmmax = 90


use:

#! /usr/bin/env python

from Tkinter import *
master = Tk()

cpmin = -90
cpmax = 90

def camera_pan(camera_pan_value):
   print(camera_pan_value)
   if(camera_pan_value == max):
       camera_pan180.set(cpmin) 

CameraPan=cpmin

CameraPan180 = Scale(master, from_=cpmin, to=cpmax, tickinterval=15, label="Camera Pan (left right)",
                                  resolution=1, orient=HORIZONTAL, length=350, width=25, command=camera_pan)
CameraPan180.set(cpmin)
CameraPan180.pack()

mainloop()

That doesn't work. I want the scale to reset to 0 after I move the slider.

Example: I slide the scale to 45 and when I release the mouse the scale automatically resets to 0 - without me having to drag it back to 0.

so change the -90 to 0 ?
