Tk eventloop

[swell]

Hi
I try/struggle to use an ActiveX component in a Tk app. When i execute
it i can catch the first event and then when i try to change the value
of the w widget everything blocks and nothing is updated anymore.

Does someone have an idea of what is wrong and how to smartly integrate
these events with the Tk event loop.

Thx
Manu

import win32com.client
import pythoncom
import MyComponent
from Tkinter import *

class Event1(MyComponent.IEvents):
def OnUpdate(self, ItemName, UserTag):
global w
v = ptrAx.getV(ItemName)
print "%s" % v
w.configure(text='a')

root = Tk()
w = Label(root,text="test")
w.pack()

ptrAx = win32com.client.DispatchWithEvents(r'MyComponent',Event1)
ptrAx.StartUpdates()

root.mainloop()
