I have encountered some problems along the way. I am using POE and Tk together so this may be the problem.

1)If I'm using Tk::TableMatrix I have no problems regarding Buttons, they are showed on the screen I'm very happy... BUT , the -variable property that is used when I create the Tk::TableMatrix needs to fit my needs as I'm using POE,so I choose to have it in  $heap->{tablearray}. If I don't define it before using it it's no problem because it's autovivified anyway ,however, if I do define it before I use it ,like this $heap->{tgarray},I get this very strange error:

bad table index "0": must be active, anchor, end, origin, topleft, bottomright, @x,y, or <row>,<col> at /usr/lib/perl5/Tk.pm line 247./code>

2)I have tried to isolate the problem. My conclusion was that Tk::TableMatrix for some reason does not let me modify text entries in cells at run-time. The testacase that supports this ideea is the following: 


use strict;
use warnings;
use Tk;
use Tk::BrowseEntry;
use Tk::TableMatrix;
use Data::Dumper qw( DumperX);
my $top = MainWindow->new;
my $stuff = {};
my $tg = $top->Scrolled(
    'TableMatrix', 
    -rows => 21, 
    -cols => 11, 
    -width => 10, 
    -height => 20,
    -titlerows => 1, 
    -titlecols => 1,
    -variable => $stuff,
    -selectmode => 'extended',
    -resizeborders => 'both',
    -titlerows => 1,
    -titlecols => 1,
    -bg => 'white',
)->pack(
    -expand => 1,
    -fill=>'both'
);

$tg->tagConfigure('active', -bg => 'gray90', -relief => 'sunken')     
+               ;
$tg->tagConfigure('title', -bg => 'gray85', -fg => 'black', -relief =>
+ 'sunken')    ;

$top->Button(
    -text=>'modify', 
    -command=> sub {
        $stuff->{'3,3'} = 'asfasf';
    },
)->pack;
Tk::MainLoop;
