[Tkinter-discuss] Exit from method loop

[Paul Simon]

Andreas,

Thanks very much for the response to my question.  Using threading is beyond my programming capability and since I am only occasionally programming would not be worth my time to learn.  I'm not clear about the second suggestion you made and would appreciate some clarification.

At the moment my intuition is telling me that the sleep statement is the source of the problem, as it might interfere with the check button selection, and the rest of the loop is too fast to catch the "click."  I'm going to replace "sleep" with a time delta construction and see if that works any better.

  Hi,


  if it should loop continuously, why don't you put it into a background thread?


  Or, as you are using sleep() remove the loop and use root.after() to invoce the check method every now and then...

    Hi All,

    I've attaached code simplified from my "opus" and have a problem.  I would
    like to exit from "read_sensor" into the main loop.  I cannot access the
    "stop" check button or the "quit" button while the intenal loop in
    "read_sensor" is running.  The internal loop is intended to run continuously
    until interrupted by the "stop" button but for demo purposes it is set to 10
    interations.

    Paul Simon
