Gtk2::Notebook - set_homogeneous_tabs(1);

[Mario Kemper <mario kemper googlemail com>]

Maybe i am blind but... 

my $notebook_settings = Gtk2::Notebook->new;
$notebook->set_homogeneous_tabs(1);

...leads to "Can't locate object method "set_homogeneous_tabs" via
package "Gtk2::Notebook"".

The property "homogeneous" is mentioned in the documentation, but i
can't find a function to deal with it. 
Any clue?

Info:
Glib built for 2.14.1, running with 2.16.4
Gtk2 built for 2.12.0, running with 2.12.9
