NAME
Gtk2::TreeIterHIERARCHY
Glib::Boxed +----Gtk2::TreeIter
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)
-
- •
- $sv_iter (scalar)
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.
scalar = $iter->to_arrayref ($stamp)
-
- •
- $stamp (integer)
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.
