I have been experiencing strange thread behavior when I pass a message
received via a Queue to a wx.PostEvent method (from wxPython). The
relevant code in the thread is:
def run(self):
while self.is_running:
task = self.queue.get()
wx.PostEvent(self.app.handle_task, task)
self.queue is a Queue.Queue instance and self.app is a wx.Window
instance
I have a case where two items are placed in the queue one after the
other, and it appears that only the first item is passed to
wx.PostEvent. If I place a time.sleep(0.1) call anywhere within the
while loop, both items get passed to wx.PostEvent. It works if I put
time.sleep before the self.queue.get(), in between get() and PostEvent
() or after PostEvent(). So it seems like a short delay is enough to
get two items handled, although it doesn't seem to matter where I
place the delay within the while loop. Does someone know what might
explain this behavior? Thanks.
