G'day aviw,

You can get and set options (including -background, -selectbackground, and lots of other -*background variations) using the cget() and configure() methods. See Tk::options.

You can bind actions to events (such as <FocusIn>, <FocusOut>, <Enter>, <Leave>, and so on) which could control colours and other options. See Tk::bind.

[ Note: In your last Tk-related post, "tk sash slide render", you did much the same as you've done here: including no code and no links to the modules you're using. You were advised about this in that post. If you want better answers, I suggest you reread that advice then provide a better question.]

Hi,

Thank you both.

I would prefer to use common TK way (-selcmd => sub{}) I do get click event yet it returns my ($NumRows,$Numcols,$selection,$noCells) = @_. based on: TableMatrix

When using -rowtagcommand I do get a call with correct row number (great!) yet I fail to find a way to color the row :/

Is the only solution is via TK:bind for each cell?

yet I fail to find a way to color the row

Hi, you can try

$t->tagRow('active', $row);

and here is a full working example. Press the Update button to see it work.

#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::TableMatrix;

my $mw = MainWindow->new;

my $arrayVar = {};

print "Filling Array...\n";
my ($rows,$cols) = (10, 10);
 foreach my $row  (0..($rows-1)){
    foreach my $col (0..($cols-1)){
      $arrayVar->{"$row,$col"} = "$row,$col";
   }
}

print "Creating Table...\n";

## Test out the use of a callback to define tags on rows and columns
sub colSub{
  my $col = shift;
  return "OddCol" if( $col > 0 && $col%2) ;
}

sub rowSub{
  my $row = shift;
  return "Oddrow" if( $row > 0 && $row%2) ;
}


 my $t = $mw->Scrolled('TableMatrix', -rows => $rows, -cols => $cols,
 -width => 6, -height => 6,
 -titlerows => 1, -titlecols => 1,
 -variable => $arrayVar,
 -coltagcommand => \&colSub,
 -colstretchmode => 'last',

 -rowtagcommand => \&rowSub,

 -rowstretchmode => 'last',
 -selectmode => 'extended',
 -selecttitles => 0,
 -drawmode => 'slow',
 -scrollbars=>'se'
 );


$mw->Button(-text => "Update", -command => \&update_table)
               ->pack(-side => 'bottom',-anchor => 'w');

#  Color definitions here:
$t->tagConfigure('active', -bg => 'white', -fg => 'red', -relief => 's
+unken');
$t->tagConfigure('OddCol', -bg => 'lightyellow', -fg => 'black');
$t->tagConfigure('title', -bg => 'lightblue', -fg => 'black', -relief 
+=> 'sunken');
$t->tagConfigure('dis', -state => 'disabled');
$t->pack(-expand => 1, -fill => 'both');
$t->focus;

Tk::MainLoop;

# $t->tagConfigure($anchor, -anchor => $anchor);
# $t->tagRow($anchor, ++$i);
# $t->set( "$i,$first",$anchor);

sub update_table {

        $t->tagCell('dis', '1,1' );
        $t->activate('2,2');
        $t->tagRow('active',3);
        
#       $t->configure(-padx =>( $t->cget(-padx)));
#       a trick needed sometimes to update

Which method have you already tried and how did it fail for you to work?

Without knowing too much about Tk, I would first try the second approach.

Tried the 2nd and found this good example:link

Yet failed to understand how to effect specific row with tagConfigure dynamically upon rowtagcommand call.
