'''on execution of button.py a button appears ,after clicking on the button it calls bounce.py but after closing bounce.py the button also closes...but i want the button to remain open...please help. im posting both the programs button.py and bounce.py NOTE: im using vpython in bounce.py and windows os'''

button.py
-------------------------------------------------------------------------------------------------------------------

from Tkinter import *
import fileinput

root = Tk()
root.title("Note Taker")
def Button1():
	execfile('bounce.py',{})

button1 = Button(root, text="bounce", command = Button1)
text = Entry(root)
button1.pack()
root.mainloop()

bounce.py

from visual import *

floor = box(length=4, height=0.5, width=4, color=color.blue)

ball = sphere(pos=(0,4,0), color=color.red)
ball.velocity = vector(0,-1,0)

dt = 0.01
while 1:
    rate(100)
    ball.pos = ball.pos + ball.velocity*dt
    if ball.y < 1:
        ball.velocity.y = -ball.velocity.y
    else:
        ball.velocity.y = ball.velocity.y - 9.8*dt

Are you wanting to embed VPython in a Tkinter application? I don't know if it is possible. I found an example where someone as done it with wxPython:

You could try using os.popen() to call a visual window instead of execfile().

Or maybe use threads?
