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


-----------


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

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


-------------------

        # 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/")
      <etc>
