Timer in Python

Question

Hi,

I am writing a python app using Tkinter for buttons and graphics and having trouble getting a timer working, what I need is a sample app that has three buttons and a label.

[start timer] [stop timer] [quit]

When I press the start button a function allows the label to count up from zero every 5 seconds, the stop button stops the timer and the quit button quits the app.

I need to be able to press stop timer and quit at any time, and the time.sleep(5) function locks everything up so I can't use that.

currently i'm using threading.timer(5,do_count_function) and getting nowhere !

I'm a vb.net programmer, so python is a bit new to me, but hey, i'm trying.

Check the .after method of your Tk() object. This allows you to use Tk's timer to fire events within the gui's own loop by giving it a length of time and a callback method.
