Tk already has "threads" :-S try this:
use Tk; my $mw = new MainWindow(); my $button = $mw->Button(-text => "HEY")->pack(); $mw->after(1,\&thread_sub); # after 1 ms, calls thread_sub # it'll run like a thread, but isn't really! # See http://www.foo.be/docs/tpj/issues/vol1_3/tpj0103-0006.html MainLoop(); sub thread_sub { for (my $i=0; $i<10_000_000; $i++) { # DO NOTHING. LET THE TIME BE TIME } # CHANGE BUTTON'S TEXT PROPERTY TO "hey" HERE $button->configure(-foreground=>'red'); }
It's a weird example though... what were you planning on doing? Do you really need threads or would Tk timeslicing do?

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 How to display code and escape characters are good places to start.
