#!/usr/bin/env python

from qt import *

	def __init__(self,target):

		while True:

		self.label.setText("No event so far")
		self.queue=Queue(self)
		self.queue.start()
	def customEvent(self,ev):
		if ev.type()==EVENTID:
			self.label.setText("event " + str(self.count))
			self.count=self.count+1
app=QApplication(sys.argv[1:])
xv=XV(app)
app.setMainWidget(xv)
xv.show()
app.exec_loop()
xv.queue.end() 
xv.queue.wait()
