I have been using various versions of TK for 20 years or so. I recently started writing scripts by starting with an example I found online. I have finally figured out the syntax to get what I want with most widgets but using this version (or whatever it is) I can not figure out how to configure things like color and font on any of the widgets. I have searched online for answers and nothing seems to help. He is a minimal test case. I just want to be able to give buttons background color active color etc etc and to have control over font type and size. 
 
use strict;
use Tkx;

my $tol = 1;        
my $main_back_color = "#EDF8F8";

Tkx::wm_title(".", "OIML lookup");
Tkx::ttk__frame(".c",  -padding => "8 2 1 1");
#.c->configure( -background => "$backcolor" );
#Tkx::ttk__frame(".c");
Tkx::grid( ".c", -column => 0, -row => 1, -sticky => "nwes");
Tkx::grid_columnconfigure( ".", 0, -weight => 1); 
Tkx::grid_rowconfigure(".", 0, -weight => 1);

Tkx::ttk__button(".c.calc", -text => "Calculate", -command => sub {cal
+culate();});
Tkx::grid(".c.calc", -column => 0, -row => 0, -sticky => "W");

Tkx::ttk__button(".c.clear", -text => "Clear", -command => sub {clear(
+);});
Tkx::grid(".c.clear", -column => 1, -row => 0, -sticky => "W");

Tkx::ttk__button(".c.wiz", -text => "Wizzard", -command => sub {wizzar
+d();});
Tkx::grid(".c.wiz", -column => 2, -row => 0, -sticky => "E");

Tkx::ttk__radiobutton(".c.rb5", -text => '.00005"',-variable=> \$tol, 
+-value=> 1);
Tkx::grid(".c.rb5", -column => 2, -row => 1, -sticky => "E");
Tkx::ttk__radiobutton(".c.rb6", -text => '.0001"',-variable=> \$tol, -
+value=> 2);
Tkx::grid(".c.rb6", -column => 3, -row => 1, -sticky => "w");

Tkx::MainLoop();
