In addition to Emmanuele's answer which relies on the implementation of
the GTK-Perl wrapper, the generic Perl answer is to use an anonymous
subroutine:

$widget->signal_connect(clicked => sub { rankChanged($arg) });
If you also want your 'rankChanged' function to get the arguments
normally passed to a 'clicked' event handler, you could pass them like
this:
$widget->signal_connect(clicked => sub { rankChanged($arg, @_) });
Strictly speaking, you're not passing values to a code ref, but defining
a code ref that has knowledge of the values.
