wxPython before MainLoop

[7stud]

I reorganized my Thread class a little bit:

------------
class MyThread(threading.Thread):
    def __init__(self, a_frame):
        threading.Thread.__init__(self)
        self.frame_obj = a_frame

    def run(self):
        result = self.long_slow_init()

        wx.CallAfter(self.frame_obj.receive_result, result)
        #CallAfter() calls the specified function with the specified
argument
        #when the next pause in execution occurs in this thread.

    def long_slow_init(self):
        print "starting long_slow_init()..."
        time.sleep(6)
        result = 20.5
        return result
