Threading wxPython app with background process for multitouch detection - events

Question

So basically I have some code for multitouch detection and I would like to run it as a separate thread which sends custom events to a wxPython GUI upon a multitouch event.
Now I could post the code for the multitouch tracking but to use it you would require a trackpad, the server app and the detection code, so I think it's better to consider a simple example for the sake of the question.
So for example lets assume an event simulator sending an event every 10 seconds:
import wx
import wx.lib.newevent
import time
MultiTouchEvent, EVT_MULTITOUCH = wx.lib.newevent.NewEvent()
class EventSimulator:
def __init__(self):
self.eventdata = 0
def Start(self):
self.RunTUIO()
def RunTUIO(self):
while True:
time.sleep(10)
wx.PostEvent(GUI, MultiTouchEvent(self.eventdata))
self.eventdata += 1
if __name__ == '__main__':
MultiTouchTracker = EventSimulator()
MultiTouchTracker.Start()
Now I would like to receive these events whenever they occur within a wxPython GUI (something like this):
import wx
class Frame(wx.Frame):
def __init__(self, title):
wx.Frame.__init__(self, None, title=title, size=(350,200))
self.Bind(EVT_MULTITOUCH, self.handler)
def handler(self, event):
data = event.data,
print data
if __name__ == '__main__':
app = wx.App(redirect=False)
window = Frame("My Basic GUI")
window.Show()
app.MainLoop()
The problem is I cannot workout how to combine these two pieces of code into a working example. As I understand it I need to run the event simulator as a separate thread from within the GUI code. Please can someone explain how to do this, thanks!

For details on multi-threading in Python see the docs for the threading module in the stock Python library. There is an example of using it in a GUI in the Threads module in the wxPython demo, although there are other viable approaches as well. (Deriving from the Thread class instead of just using one, etc.) That demo module also shows a convenient way to make a new event class and binder using the wx.lib.newevent module.
