In my application, I want to trigger a timer once per second to update a pair of static text
 objects on the display.  (With the current sidereal time, for the curious).

Marcus - I stole this from Scandoo and use it all the time:


class UpdateTimer(wx.Timer):
    def __init__(self, target, dur=1000):
        self.target = target

    def Notify(self):
        """Called every timer interval"""
        if self.target:


        # start a timer to check for web commands
        self.timer = UpdateTimer(self, 1000) # every 1000 mSec, 1 Sec


    # timer events - check for web commands
    def OnUpdate(self):
      cmds = os.listdir("/var/www/cgi-bin/commands/")
