  • I doubt you really mean to be adding all those new buttons everytime you click 'next', right? You might want to read up about how the Tk event loop works.
  • You had the syntax for -command incorrect. You either pass it an anonymous subroutine (as in the $button2 example below) or a code reference, with \&
See below for corrected code.
use warnings; use Tk; sub one; my $main = MainWindow->new; my $button; my $button2; my $label1; $label1 = $main->Text ( '-width'=>'50')->pack; $button = $main->Button( -text=>'next', -command=>\&one)->pack; $button2 = $main->Button( -text=>'quit', -command=>sub{exit;})->pack; our $foo = "0"; MainLoop; sub one { my $talk="Hey, that was click $foo\n"; $foo++; $label1 -> insert('1.0',$talk); }

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.
