Something like:

my ($x, $y, $width, $height) = @{$window->allocation};
($x, $y) = $window->window->get_root_origin;

will get you the data. On app startup you just:
$window->set_default_size($width, $height);
$window->set_uposition($x, $y);

With enlightement you may need to use get_deskrelative_origin
instead of get_root_origin, I don't remeber the details....

This is generated by Gtk+ itself, you don't want to call get_parent_window
on a toplevel widget because toplevels don't have parent windows.
