Use a Tk::Spinbox, see

See Re: can'yt figure out whats wrong in this code?, Re: Perl/Tk,How to limit the number of characters in Entry? and widget - Demonstration of Perl/Tk widgets, Entries and Spin-boxes: 3. Validated entries and password fields.

#!/usr/bin/perl -- use strict; use warnings; use Tk; my $mw = tkinit; for my $ix ( 0 .. 9 ){ my $box = $mw->Spinbox(qw/ -from -10 -to 10 -increment .01 -format %05.2f -width 10 /, )->pack ; $box->set( $ix ); } $mw->WidgetDump; MainLoop;

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.
