When I try to do the following example: 
#http://habrahabr.ru/blogs/perl/65774/

use Tkx;

my $mw = Tkx::widget->new('.'); #Main Window

#buttons
my @btns = (
    $mw->new_ttk__button(-text=>'button 1'),
    $mw->new_ttk__button(-text=>'button 2'),
    $mw->new_ttk__button(-text=>'button 3')
);

#Place elements (buttons) in table grid
#column x row coordinates
$btns[0]->g_grid(-row=>0, -column=>0);
$btns[1]->g_grid(-row=>0, -column=>1);
$btns[2]->g_grid(-row=>1, -column=>1);

#Event Loop
Tkx::MainLoop();

It gives me an error:
invalid command name "ttk::button" at "script.pl" line ##
When I add after 
use Tkx;

[download]
the following: 
Tkx::package_require('ttk');

[download]
It gives me an error that it cannot find the "ttk" package:
can't find package ttk at "script.pl" line ##
Either way, I tried to capitalize "Ttk". Same thing happens.
So, I had to do: 
use Tkx;

my $mw = Tkx::widget->new('.'); #Main Window

#buttons
#used to be:
#$mw->new_ttk__button(-text=>'button 1')
#now:
#$mw->     new_button(-text=>'button 1')
my @btns = (
    $mw->new_button(-text=>'button 1'),
    $mw->new_button(-text=>'button 2'),
    $mw->new_button(-text=>'button 3')
);

#Place elements (buttons) in table grid
#column x row coordinates
$btns[0]->g_grid(-row=>0, -column=>0);
$btns[1]->g_grid(-row=>0, -column=>1);
$btns[2]->g_grid(-row=>1, -column=>1);

#Event Loop
Tkx::MainLoop();

And it works that way, but I figure that ttk is the package that allows for themed widgets, but when I use regular button, as I did in the last code above, it is a standard blocky widget.

Does anybody know how the person that made the example with ttk, managed it to work?

I have:
ActiveState perl, v5.10.0 built for MSWin32-x86-multi-thread
