Interesting posts in the thread that you referenced. I didn't have time to run any actual code, but it appears to me that in one post, Tk as running in one thread and a single worker in another thread. Communication between the two threads was via shared memory with a simple lock mechanism. "msg ready" only set by the worker thread and only cleared by the Tk thread. The worker wouldn't be able send another message until the Tk thread clears the shared memory semaphore "msg ready" flag.

I suspect that there is an answer where the Tk thread polls a shared memory structure every 100 ms or so and accepts work if there is any to be done. Tk cannot wait at an exchange indefinitely or the other GUI buttons will "hang".

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
