# Gtk::TreeRowReference Class Reference
[TreeView Classes]

List of all members.

## Detailed Description

Typedefed as Gtk::TreeModel::RowReference.

This reference will keep pointing to the node pointed to by the Path, so long as it exists. It listens to all signals emitted by the Model, and updates its Path appropriately.

## Public Member Functions
Glib::RefPtr<const TreeModel> | get_model () const
| Returns the model which reference is monitoring in order to appropriately the path.
Glib::RefPtr<TreeModel> | get_model ()
| Returns the model which reference is monitoring in order to appropriately the path.
TreeModel::Path | get_path () const
| Returns a path that the row reference currently points to, or `0` if the path pointed to is no longer valid.
const GtkTreeRowReference* | gobj () const
| Provides access to the underlying C instance.
GtkTreeRowReference* | gobj ()
| Provides access to the underlying C instance.
GtkTreeRowReference* | gobj_copy () const
| Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.
bool | is_valid () const
| Returns `true` if the reference is non-`0` and refers to a current valid path.
| operator bool () const
| The same as is_valid().

## Member Function Documentation

Glib::RefPtr<const TreeModel> Gtk::TreeRowReference::get_model | ( |  | ) | const

| Returns the model which reference is monitoring in order to appropriately the path. Returns: The model, or `0`. Since gtkmm 2.8:

Glib::RefPtr<TreeModel> Gtk::TreeRowReference::get_model | ( |  | ) |

| Returns the model which reference is monitoring in order to appropriately the path. Returns: The model, or `0`. Since gtkmm 2.8:

TreeModel::Path Gtk::TreeRowReference::get_path | ( |  | ) | const

| Returns a path that the row reference currently points to, or `0` if the path pointed to is no longer valid. Returns: A current path, or `0`.

const GtkTreeRowReference* Gtk::TreeRowReference::gobj | ( |  | ) | const`[inline]`

| Provides access to the underlying C instance.

GtkTreeRowReference* Gtk::TreeRowReference::gobj | ( |  | ) | `[inline]`

| Provides access to the underlying C instance.

GtkTreeRowReference* Gtk::TreeRowReference::gobj_copy | ( |  | ) | const

| Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.

bool Gtk::TreeRowReference::is_valid | ( |  | ) | const

| Returns `true` if the reference is non-`0` and refers to a current valid path. Returns: `true` if reference points to a valid path.

Gtk::TreeRowReference::operator bool | ( |  | ) | const

| The same as is_valid().

## Friends And Related Function Documentation

void swap | ( | TreeRowReference& | lhs,
|  | TreeRowReference& | rhs
| ) | `[related]`

  | Parameters:
  | lhs | The left-hand side
  | rhs | The right-hand side

Gtk::TreeRowReference wrap | ( | GtkTreeRowReference* | object,
|  | bool | take_copy = `false`
| ) | `[related]`

  | Parameters:
  | object | The C instance
  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.
Returns: A C++ instance that wraps this C instance.
