我们从Python开源项目中,提取了以下7个代码示例,用于说明如何使用win32event.QS_ALLEVENTS。
def WaitWhileProcessingMessages(event, timeout = 2): start = time.clock() while True: # Wake 4 times a second - we can't just specify the # full timeout here, as then it would reset for every # message we process. rc = win32event.MsgWaitForMultipleObjects( (event,), 0, 250, win32event.QS_ALLEVENTS) if rc == win32event.WAIT_OBJECT_0: # event signalled - stop now! return True if (time.clock() - start) > timeout: # Timeout expired. return False # must be a message. pythoncom.PumpWaitingMessages()
def start(self): if self.instance_running(): try: self.stop() except SystemExit: return win32gui.PostQuitMessage(0) # Load today's count data back from data file super(KeyCounter, self).start() self.hook_keyboard() self.create_window() self.update_tray_icon() while 1: try: win32event.MsgWaitForMultipleObjects( [], 0, self.MSPF, win32event.QS_ALLEVENTS ) win32gui.PumpWaitingMessages() except SystemExit: win32gui.PostQuitMessage(0)
def demo (delay=1000, stop=10): g = glork(delay, stop) # Timers are message based - so we need # To run a message loop while waiting for our timers # to expire. start_time = time.time() while 1: # We can't simply give a timeout of 30 seconds, as # we may continouusly be recieving other input messages, # and therefore never expire. rc = win32event.MsgWaitForMultipleObjects( (g.event,), # list of objects 0, # wait all 500, # timeout win32event.QS_ALLEVENTS, # type of input ) if rc == win32event.WAIT_OBJECT_0: # Event signalled. break elif rc == win32event.WAIT_OBJECT_0+1: # Message waiting. if win32gui.PumpWaitingMessages(): raise RuntimeError("We got an unexpected WM_QUIT message!") else: # This wait timed-out. if time.time()-start_time > 30: raise RuntimeError("We timed out waiting for the timers to expire!")
