Tk - Tick box size change

merrymonk has asked for the wisdom of the Perl Monks concerning the following question:

Although I have used Perl Tk for a number of years I never have wanted to do this before.
I want to alter both the size of the tick box in a Checkbutton and the size of the round button of a Radio button.
I could not see any obvious option for this so I thought it may be affected my the text size on the widget.
The Perl below creates 2 Checkbuttons with different sizes of text. However the tick boxes are the same size.
Is there a way of altering the tick box size? I could want differenmt sizes on various widgets.

use Tk;
use strict;
my $mw = MainWindow->new(-title => 'CheckBox size');
my $f = $mw->Frame->pack(-side => 'top');

my $weight = "normal";

my $fch = $f->Checkbutton(

     -text     => "Weight",

    -variable => \$weight,

)->pack(-side => 'left');

my $size = 16;
$fch->configure(-font => [ -size => $size ]);

my $fch2 = $f->Checkbutton(

     -text     => "Weight",

    -variable => \$weight,

)->pack(-side => 'left');

$size = 32;
$fch2->configure(-font => [ -size => $size ]);

MainLoop;

Your options seem to be either to supply your own images for the checked and unchecked checkboxes to Checkbutton or use a different checkbutton object. I found Tk::Checkbox has the option of setting the size. I don't see how to add text next to it so you likely will need to add your own label. use warnings; use strict; use Tk; use Tk::Checkbox; my $mw = MainWindow->new(-title => 'CheckBox size'); my $f = $mw->Frame->pack(-side => 'top'); my $weight1 = "normal"; my $fch = $f->Checkbutton( -text => "Weight", -variable => \$weight1, )->pack(-side => 'left'); my $size = 16; $fch->configure(-font => [ -size => $size ]); my $weight2 = "Weight"; my $fch2 = $f->Checkbox( -variable => \$weight2, -command => sub {print "$weight2\n"}, -onvalue => "Weight", -offvalue => "Mass", -size => 25, )->pack(-side => 'left'); MainLoop; [download] I found it was tricky to install `Tk::Checkbox` in CPAN since `install Tk::Checkbox` doesn't work and `i /Tk::Checkbox/` doesn't find anything. I had to use `install MIKRA/Tk-MK-0.23.tar.gz`.	[reply] [d/l] [select]

Thank you. I was hoping it would have been more straightforward however, I will try and use what you have suggested.	[reply]

It looks like you can also place buttons on a canvas and then scale the canvas. I don't have time to dig into this and there are monks around who are experienced with Perl/Tk who might be able to provide an example. Edit: Here is a Perlmonks node that deals with scaling canvases but not really scaling buttons. It might give you something to go on.	[reply]
