[Tutor] Auto Refresh

[Hi]

Thank you for the reply, SetLabel is exactly what I am looking for. And yes,
you were correct, I just typoed the var_rate() when I was composing the
email. So what I did is in my main GUI class:

    wx.StaticText(self, -1, sampling rate':', (107, 150))
    self.rate_status = wx.StaticText(self, -1, '', (190, 150))    #just to
initialize rate_status to some location

    def refresh(self, event):
    x = rate()
    rate_text = self.rate_status.SetLabel(str(x.rate_var()))


and in my class that contains the variable (which will change every so often
at the end, so right now I'm modeling this with a random generator):

class rate():

    def rate_var(self):
    samp_rate = random.randint(44100, 48000)
    return samp_rate

I want to make it so once def refresh ran, it will continuously update and
display the new value in samp_rate in my main GUI at some time interval, say
every 10 seconds. I have looked up Timer, but I have not been able to make
it work. I looked up the documentation in Python's website to no avail. Can
anyone suggeste anything to help me?
