SYNOPSIS

  package MyCustomListStore;


  use Glib::Object::Subclass
      Glib::Object::,
      interfaces => [ Gtk2::TreeModel:: ],
      ;


  ...


  sub set {
      my $list = shift;
      my $iter = shift; # a Gtk2::TreeIter


      # this method needs access to the internal representation
      # of the iter, as the model implementation sees it:
      my $arrayref = $iter->to_arrayref ($list->{stamp});
      ...
  }

DESCRIPTION

The methods described here are only of use in custom Gtk2::TreeModel implementations; they are not safe to be used on generic iters or in application code. See CREATING A CUSTOM TREE MODEL in Gtk2::TreeModel for more information.

METHODS

treeiter = Gtk2::TreeIter->new_from_arrayref ($sv_iter)

Create a new Gtk2::TreeIter from the internal array reference representation used by custom Gtk2::TreeModel implementations. This is the complement to Gtk2::TreeIter::to_arrayref(), and is used when you need to create and return a new iter from a method that is not one of the Gtk2::TreeModelIface interface vfuncs. See CREATING A CUSTOM TREE MODEL in Gtk2::TreeModel for more information. Convert a boxed Gtk2::TreeIter reference into the internal array reference representation used by custom Gtk2::TreeModel implementations. This is necessary when you need to get to the data inside your iters in methods which are not the vfuncs of the Gtk2::TreeModelIface interface. The stamp must match; this protects the binding code from potential memory faults when attempting to convert an iter that doesn't actually belong to your model. See CREATING A CUSTOM TREE MODEL in Gtk2::TreeModel for more information.
