use Gtk2 '-init';

$window = Gtk2::Window->new('toplevel');
$window->set_title("Hello World!");

$button = Gtk2::Button->new("Press me");
$button->signal_connect(clicked => sub { print "Hello again - the button was pressed\n"; });




The sample program creates a GTK+ Window titled "Hello World!". The window contains a Button labelled "Press me." When the button is pressed, the message "Hello again - the button was pressed" is displayed on the console via the callback inside the anonymous subroutine connected to the "clicked" signal.
