( #3333=superdoc: print w/replies, xml ) Need Help??

I use the below for a Pane widget which is to hold a Label widget which is to hold a multi-line string for display in a pop-up window.

# Calculate dimensions of message for pane, etc. Then # configure widget to that height and width. sub size_widget_for_string { my ($wgt, $msg, $font) = @_; # Measure widest line of string for given font. my @msg = split "\n", $msg; my $hght = 1.5 * $wgt->fontMetrics($font, -linespace); my $wdth = 0; foreach (@msg) { my $line_wdth = $wgt->fontMeasure($font, " $_ "); $wdth = $line_wdth if $wdth < $line_wdth; $hght += $wgt->fontMetrics($font, -linespace); } # Limit size to reasonable maximums. my $max_hght = 0.6 * $wgt->screenheight; my $max_wdth = 0.9 * $wgt->screenwidth; $hght = $max_hght if $hght > $max_hght; $wdth = $max_wdth if $wdth > $max_wdth; # Configure the widget. $wgt->configure( -width => $wdth, -height => $hght ); }


size_widget_for_string($pane, $any_old_string, 'courier');

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.
