[Pythonmac-SIG] Tkinter problem in a forked

[Eric Texier]

Hi,
I am having trouble with running tk in a child process. the code worked 
on linux.
It crashed with the following message:

creating window in receptionist
Tcl_FinalizeNotifier: notifier pipe not initialized
Abort

Any idea if it's a bug or something extra that I need to do of macox.
Thanks,
Eric


import os, sys
from Tkinter import *

class receiver:
    def __init__(self, pipeFromParent):
    try:
        print "creating window in receptionist"
        Tk(className='foork',screenName = None,baseName = None)
        print "creating window in receptionist DONE"
    except:
        sys.exit(1)
    
        
tkinter.createfilehandler(pipeFromParent,tkinter.READABLE,self.msgFromParent)
    self.Frame = Frame()
        self.Frame.master.protocol("WM_DELETE_WINDOW", self.quit)
        self.Frame.mainloop()

    def quit(self):
    print "in quit"

    def msgFromParent(self,file=None,mask=None):
    print "in msgFromParent file: ",file," mask: ",mask
    sys.exit(0)

def startReceiver():
    pipeReceiver = os.pipe()
    pid = os.fork()

    if pid == 0:
    # child process
        os.close(pipeReceiver[1])
    receiver(pipeReceiver[0])
        sys.exit(0)

    # parent process
    os.close(pipeReceiver[0])   
    return    pipeReceiver[1]

pipeReceiver = startReceiver()
win = Tk(className = "main")
win.mainloop()
