NAME

       Gtk2::TreeIter

HIERARCHY

	 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)
       o   $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.

   $iter->set ($from)
       o   $from (scalar)

       Set the contents of $iter.  $from can be either another Gtk2::TreeIter or an "internal" arrayref form as above.

       Often you create a new iter instead of modifying an existing one, but "set" lets you to implement things in the style of the "remove"
       method of Gtk2::ListStore and Gtk2::TreeStore.

       A set can also explicitly invalidate an iter by zapping its stamp, so nobody can accidentally use it again.

	   $iter->set ([0,0,undef,undef]);

   scalar = $iter->to_arrayref ($stamp)
       o   $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.

INTERFACES

METHODS

   treemodelfilter = Gtk2::TreeModelFilter->new ($child_model, $root=undef)
       o   $child_model (Gtk2::TreeModel)

       o   $root (Gtk2::TreePath or undef)

       o   $child_iter (Gtk2::TreeIter)

   treepath or undef = $filter->convert_child_path_to_path ($child_path)
       o   $child_path (Gtk2::TreePath)

   treeiter = $filter->convert_iter_to_child_iter ($filter_iter)

   treepath or undef = $path->convert_path_to_child_path ($filter_path)

   treemodel = $filter->get_model
   $filter->set_modify_func ($types, $func=undef, $data=undef)
       o   $types (scalar) type name string for one column, or an arrayref of type names for multiple columns

       o   $func (scalar)

       o   $data (scalar)

       func is called as

	   sub myfunc {
	     my ($filter, $iter, $column_num, $data) = @_;
	     ...

       and should return the value from the filtered model that iter row and column number.

   $filter->refilter
   $filter->set_visible_column ($column)
       o   $column (integer)

   $filter->set_visible_func ($func, $data=undef)
       o   $func (scalar)

       o   $data (scalar)

PROPERTIES

       'child-model' (Gtk2::TreeModel : readable / writable / construct-only / private)
	   The model for the filtermodel to filter

       'virtual-root' (Gtk2::TreePath : readable / writable / construct-only / private)
	   The virtual root (relative to the child model) for this filtermodel
