Here's the scoop:
Upon upgrading my system to Redhat 7.1 (and thus to perl
5.6), my pet program broke. I've isolated the problem, and
it lies it the Scrolled function. Here's an example
which should, as far as I can tell, work properly.
use strict;
use Tk;
my $mw = MainWindow->new( -title => 'Test' );
my $listbox = $mw->Scrolled( 'Listbox' );
my @list = ( qw ( foo bar baz batz dingo dongo dango
floo blar blaz blatz zingo zongo zango
fi ba be bz uno duo trio quitro ) );
for my $item (@list) {
$listbox->insert( 'end', $item );
}
$listbox->pack( -expand => 1, -fill => 'both' );
MainLoop;
This code is taken almost verbatim from a
writeup
by
ichimunki,
so I trust that it works. But on my system, it
doesn't.
I tried resizing the scrollbars to something more sensible
by adding the following code:
my $xsb = $listbox->Subwidget("xscrollbar");
my $ysb = $listbox->Subwidget("yscrollbar");
$xsb->configure(-width => 10);
$ysb->configure(-width => 10);
This half solves the problem, but still leaves pretty blatant
layout
issues.
Any ideas? Has anybody seen this problem?

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).
