ayuda, con classes

[alvaro tovar]

hola, estoy tratando de hacer un programa con hilos, pero tengo un problema,
y no se como resolverlo,

wxPython

-----------------------
import wx
from threading import Thread
ID_ABOUT=101
ID_EXIT=110


class Dialogo(wx.Frame):
        control=None
        def __init__(self,parent,id,title):
            wx.Frame.__init__(self,parent,wx.ID_ANY, title, size =
(200,100))
            self.control = wx.TextCtrl(self, 1, style=wx.TE_MULTILINE)
            self.control.write('fdfda')
            self.control.write('fdfda')
            self.CreateStatusBar() # A Statusbar in the bottom of the window
           # Setting up the menu.
            filemenu= wx.Menu()
            filemenu.Append(wx.ID_ABOUT, "&About"," Information about this
program")
            filemenu.AppendSeparator()
            filemenu.Append(wx.ID_EXIT,"E&xit"," Terminate the program")
               # Creating the menubar.
            menuBar = wx.MenuBar()
            menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the
MenuBar
            self.SetMenuBar(menuBar)  # Adding the MenuBar to the Frame
content.
            self.Show(True)
        def escribir(self,tex):
            self.control.write(tex)
class v(Thread):

    frame=None

    def run(self):
        app = wx.PySimpleApp()
        self.frame = Dialogo(None, -1, "Sample editor")
        print 'corre',self.frame
        print 'dialogo',self.frame.__class__
        print dir(self)
        print dir(self.frame)
        app.MainLoop()


------------------------------


y


servidor
------------------------------



mport socket,thread
from wxPython import *

def leerYescribir(canal,*args):
    print 'ller escribir'
    ventana=v()
    ventana.start()
#    thread.start_new_thread(d.correr,())
#    thread.start_new_thread(correr,())
    print 'fdsf'
    print ventana.__class__,dir(ventana)
    print ventana.frame.__class__ ,dir(ventana.frame.__class__)
    thread.start_new_thread(leer, (canal,ventana.frame))
    thread.start_new_thread(escribir, (canal,ventana.frame))

def leer(canal,ventana):
    while True:
        print 'a escuchar\n'
        print dir(ventana)
        ventana.control.write('de: '+canal.recv(100)+'\n')


------------------------


corro el servidor

y me sale esto

Unhandled exception in thread started by <function leer at 0x018C3170>
Traceback (most recent call last):
  File "E:\aat\eclipse-SDK-3.2-win32\eclipse\workspace\chat\src\servidor.py",
line 20, in leer
a enviar

escribe :
    ventana.control.write('de: '+canal.recv(100)+'\n')
AttributeError: 'NoneType' object has no attribute 'control'

dice que ventana no tiene el atributo control y que es de tipo NoneType,
pero no deberia, ventana es de tipo diaogo. en leerYescribir ventana es de
tipo v, y v.frame es Dialogo.

gracias
