## 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.

## Member Function Documentation

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

Returns the model that the row reference is monitoring.

Since gtkmm 2.8:

Returns:
  The model.

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

Returns the model that the row reference is monitoring.

Since gtkmm 2.8:

Returns:
  The model.

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Returns a path that the row reference currently points to, or `0` if the path pointed to is no longer valid.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().

TreeRowReference& Gtk::TreeRowReference::operator= | ( | const TreeRowReference& | other | ) |

void Gtk::TreeRowReference::swap | ( | TreeRowReference& | other | ) |

## 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]`

A Glib::wrap() method for this object.

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.
