Hi, see
Need help finding which column/row the mouse cursor is over in Tk.... You might be able to get your current scrollbar position, then use $scrollbar->set(first, last); to adjust your new range. You may even be able to juggle the code in the -scrollcommand option, and use the -fixedrows and or -fixedcolumns options to select your range. Here is something that you could look at to start your mind working.
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::Table;
my $mw= tkinit;
#$mw->geometry("400x400+100+100");
my $table = $mw->Scrolled('Table',
-rows =>2,
-columns => 100,
-fixedrows => 2, #trick to hide scrollbars
-fixedcolumns => 5,
-scrollbars => 'soe',
-takefocus => 1,)->pack(-fill=>'both',
-expand=>1);
my %widgets;
for my $row(1..10){
for my $col(1..100){
$widgets{$row}{$col} = $table->Button(
-text=> "$row - $col",
-background => 'white',
-command => sub{ do_me($row,$col) }
);
$table->put( $row,$col,$widgets{$row}{$col} );
}
}
MainLoop;
sub do_me{
my ($row, $col) = @_;
print "$row $col\n";
}

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).
