python - 如何偶尔刷新一次Python脚本？

Question

所以我创建了一个类，其中包含使用 wxPython 的 GUI。你如何让它每分钟刷新一次？

对于间隔发生的事情，请使用 Timer 。来自 WxPyWiki :

def on_timer(event):
    pass  # do whatever

TIMER_ID = 100  # pick a number
timer = wx.Timer(panel, TIMER_ID)  # message will be sent to the panel
timer.Start(100)  # x100 milliseconds
wx.EVT_TIMER(panel, TIMER_ID, on_timer)  # call the on_timer function

For some reason, this code didn't work when I tried it. The reason was the timer had to be a class member. If you put that code into the init() method and add self. before timer, it should work. If it doesn't, try making on_timer() a class member too. -- PabloAntonio

I've had problems closing my frame, when there was a Timer running.

Here's how I handled it:

def on_close(event):
    timer.Stop()
    frame.Destroy()

wx.EVT_CLOSE(frame, on_close)
