You need to obtain a TK::Font object for the font you wish to use, then call the measure( $text ) method: #! perl -slw
use strict;
use Tk;
use Tk::Font;
my $mw = MainWindow->new();
for my $name ( 'system' ) { #$mw->fontNames
print "Using font $name";
my $font = $mw->fontCreate( $name );
for my $text (
'The quick brown fox jumps over the lazy dog',
'THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG'
) {
printf "$text measures %d pixels\n", $font->measure( $text );
}
}
__END__
C:\test>junk44
Using font system
The quick brown fox jumps over the lazy dog measures 302 pixels
THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG measures 409 pixels
See the Tk::Font POD for (a little) more info, then google for more.

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).
