in reply to Window with background image and transparent listbox

Yes. It's possible, but it's a lot of work. Here's an example of a transparent window with a cyan-colored circle by zentara. Reverse it and see what you can come up with.
#!/usr/bin/perl use warnings; use strict; use Tk; use Tk::Zinc; my $width = 100; my $height = 100; my $mw = MainWindow->new(-background => 'cyan' ); #$mw->geometry($width.'x'.$height.'+300+300'); $mw->geometry('500x500+300+300'); #$mw->overrideredirect(1); my $zinc = $mw->Zinc(-width => $width, -height => $height, -reshape => 1, #clips zinc -fullreshape => 1, #clips $mw and xterm -backcolor => 'blue', )->pack; my $petal = $zinc->add('curve',1,[[$width/2,0], [2*$width,0, 'c'], [2*$width,$height, 'c'], [$width/2,$height], [-$width,$height, 'c'], [-$width,0, 'c'], [$width/2,0]], -tags => ['bezier1'], -filled => 1, #-fillcolor => 'cyan', #attempt at semi-transparency -fillcolor => "=radial 0 0 |yellow;40|black;40 50|cyan;40", + -closed => 1, -linewidth => 0, -priority => 1, -visible => 1, ); # using the triangulaire curve to reshape both TkZinc and Mainwindow w +idgets $zinc->itemconfigure(1, -clip => $petal); MainLoop;
