Python Integrating pygame and tk

Does anyone know how to integrate pygame with Tk? I am trying to drive a pygame display with a Tk form and I'm having difficulties. Below is a simple example of the kind of thing I'm trying to accomplish. I'm trying to get input from a Tk form to trigger action in the pygame window. I'm not sure how to get past the basic interaction. Any one done this type of thing? advice?

# The following code has 2 major problems.
#  1.  The window does not refresh when it is dragged over the pygame field.
#  2.  How to plot variables on the screen when the 'Draw' button is clicked?

from Tkinter import *
import os, sys, pygame
from pygame.locals import *

pygame.init()

size = width, height = 1200, 800 
CENTER = width/2, height/2

class Application(Frame):

    def draw_circle(self):
        print "How do I draw a circle at (x,y) radius?"
        print "Does this code belong here?"

    def createWidgets(self):
        myXFrame = Frame(self, bd=2, relief=RIDGE)
        Label(myXFrame, text='X:').pack(side=LEFT, padx=5)
        myX = StringVar()
        Entry(myXFrame, textvariable=myX, bg='white').pack(side=RIGHT, padx=5)
        myX.set('X')
        myXFrame.pack(expand=1, fill=X, pady=10, padx=5)

        myYFrame = Frame(self, bd=2, relief=RIDGE)
        Label(myYFrame, text='Y:').pack(side=LEFT, padx=5)
        myY = StringVar()
        Entry(myYFrame, textvariable=myY, bg='white').pack(side=RIGHT, padx=5)
        myY.set('Y')
        myYFrame.pack(expand=1, fill=X, pady=10, padx=5)

        radiusFrame = Frame(self, bd=2, relief=RIDGE)
        Label(radiusFrame, text='Radius:').pack(side=LEFT, padx=5)
        radius = StringVar()
        Entry(radiusFrame, textvariable=radius, bg='white').pack(side=RIGHT, padx=5)
        radius.set('radius')
        radiusFrame.pack(expand=1, fill=X, pady=10, padx=5)

        self.DRAW = Button(self)
        self.DRAW["text"] = "DRAW"
        self.DRAW["fg"]   = "red"
        self.DRAW["command"] =  self.draw_circle 
        self.DRAW.pack({"side": "left"})

    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.pack()
        self.createWidgets()

def main():

I've tried this. The main idea is to set a timer event using root.after(miliseconds, call_back). This will tirgger the pygame part in your Tk program.

Here's an example.

import pygame
import Tkinter as tk
from random import randint
class MyGame:
    def __init__(self):
        self.root = tk.Tk()
        tk.Button(self.root, text='Click Me', command=self.add_point).pack()

        pygame.display.init()
        self.screen = pygame.display.set_mode((200, 200))
        self.screen.fill(0xffffff)
        pygame.display.flip()

        self.cnt = 0

    def add_point(self, r=20):
        pygame.draw.circle(self.screen, randint(0, 0xffffff), 
                (randint(10, 190), randint(10, 190)), r)
        pygame.display.flip()

    def loop(self):
        # do logic
        # do render
        self.cnt += 1
        if self.cnt % 10 == 0:
            self.add_point(3)
        self.root.after(5, self.loop)

    def mainloop(self):
        self.root.after(5, self.loop)
        self.root.mainloop()

MyGame().mainloop()

Click the button and the pygame window will react you.

have you looked at PyToolkit? It looks like the bridge you're looking for. Hmm, except, no, the download links are dead :-(
