See Re: A TableMatrix row selection question :)

1. Where do I find what are all the fields that a Perl/Tk programmer can access from an XEvent object and what do those fields stand for?

The source :) The internet 1 2 :) Tk::WidgetDump

The source..

:) So as you can see you need to read Tk::event/https://metacpan.org/pod/Tk::bind#BINDING-CALLBACKS-AND-SUBSTITUTIONS ;) and use Tk::WidgetDump to see the available/mapped bindings and things of that nature :) play with this 

#!/usr/bin/perl --
use strict;
use warnings;
use Tk;
my $mw = tkinit();
my $mb = $mw->Button()->pack;
$mb->configure(
    '-command' =>
    sub { ## closure here
        print join "\n",
            $Tk::event,
            $mb->XEvent,
            $mb,
            $Tk::widget,
            '',
        ;;;;;
        
    },
);
$mw->WidgetDump;
$mw->MainLoop();
__END__
Assuming 'require Tk::WidgetDump;' at - line 20.
XEvent=SCALAR(0x113de0c)
XEvent=SCALAR(0x113de0c)
Tk::Button=HASH(0xf44d9c)
Tk::Button=HASH(0xf44d9c)

2. In the selectionSet and selectionIncludes methods the above specified thread used the values: '@' . $Ev->x . "," . $Ev->y what does this @ and the full expression stand for. I could not find anything in the perldocs for TableMatrix (and other widgets like TList decendants which also have these methods).

Read it out loud? 

$w->activate('@' . $Ev->x.",".$Ev->y);
$w->BeginExtend( $w->index('@' . $Ev->x.",".$Ev->y));

[download]

on $widget call activate with "at" x coordinate, y coordinate

on $widget call index with "at" x coordinate, y coordinate

:) So then you lookup methods activate/index to find out what the coordinates mean ... Tk::Text is chock full of coordinate stuff

As I'm still trying to learn Perl and Perl/Tk I had to spend few hours trying to look around but to no avail.

Why are you looking inside about this?
