Tk has limitations, but not this one;-).

In this case, you have to pass the widget into your sub. For example:
#!/usr/bin/perl use Tk; use strict; use constant BUTTON_WIDTH => 20; my $mw = new MainWindow(title => "demo"); my $button = $mw->Button(text => "color", width => BUTTON_WIDTH) ->pack; $mw->Button(text => "red", width => BUTTON_WIDTH, command => sub {change_color($button, "red")}) ->pack; $mw->Button(text => "green", width => BUTTON_WIDTH, command => sub {change_color($button, "green")}) ->pack; MainLoop; sub change_color { my ($widget, $color) = @_; $widget->configure(background => $color); }

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.
