i have a perl/tk program witch is just a text widget, and a button, and i want the text to change everytime i click the button. so i need to be able to change the command of the button each time it is clicked, does anybody know how to do this? here is the code:
#!/usr/bin/perl use strict; use warnings; use Tk; sub one; my $main = MainWindow->new; my $label1 = $main->Text ( '-width'=>'50' )->pack; my $button = $main->Button ( -text=>'next', -command=>sub{one} )->pack; MainLoop; sub one { my $talk2="number1"; my $talk="this text will be changing after every click of the butt +on."; $label1 -> insert('1.0',"$talk"); my $button = $main->Button(-text=>'next',-command=>sub{two})->pack +; } sub two { # change the text box again }

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.
