i guess i don't understand what you're saying.  let me back up:

i just wrote a test program:

  #!/usr/bin/perl -w

  use strict;
  use Gtk2 -init;
  use Data::Dumper;

  my $root = Gtk2::Gdk->get_default_root_window;
  print Dumper($root);

and it showed me

  $VAR1 = bless( {}, 'Gtk2::Gdk::Window' );

then i changed the line to

  my $root = Gtk2::Gdk->get_default_root_window ('');

and it died with

  Usage: Gtk2::Gdk::get_default_root_window(class) at test.pl line 7.


the class parameter in the usage statement is the one on the left side of the
arrow when called as a method.  whatever's on the left side of the arrow gets
passed as the first parameter, and in this instance, the actual XS function
ignores its only parameter, which is required only to allow the method syntax.
 if i remove the argument from the XS declaration, the method syntax ceases to
work.

do you not see this behavior?  are you sure that the XS declaration in
GdkWindow.xs is the only one you have?  (you earlier sent a patch which
included that function in Gdk.xs)
