## Public Member Functions

Constructors

- TreeRowReference (TreeModel &model, const TreePath &path)
    Constructs a row reference based on path.
- TreeRowReference (G::Object &proxy, TreeModel &model, const TreePath &path)
    Constructs a row reference based on path.
- TreeRowReference (GtkTreeRowReference *reference)
    Constructs a row reference from an existing GtkTreeRowReference.
- TreeRowReference (GtkTreeRowReference *reference, bool copy)
    Constructs a row reference from an existing GtkTreeRowReference.
- TreeRowReference (const TreeRowReference &src)
    Copy constructor.
- ~TreeRowReference ()
    Destructor.
- TreeRowReference & operator= (const TreeRowReference &src)
    Assignment operator.

Accessors

- GtkTreeRowReference * gtk_tree_row_reference () const
    Get a pointer to the GtkTreeRowReference structure.
- operator GtkTreeRowReference * () const
    Conversion operator; safely converts a TreeRowReference to a GtkTreeRowReference pointer.
- Pointer< TreePath > get_path () const
    Returns a path that the row reference currently points to, or null if the path pointed to is no longer valid.
- bool valid () const
    Returns true if the reference is non-null and refers to a current valid path.

## Static Public Member Functions

- void inserted (const G::Object &proxy, const TreePath &path)
    Lets a row reference created by the proxy object constructor know that the model emitted the "row_inserted" signal.
- void deleted (const G::Object &proxy, const TreePath &path)
    Lets a row reference created by the proxy object constructor know that the model emitted the "row_deleted" signal.
- void reordered (const G::Object &proxy, const TreePath &path, const TreeIter &iter, int *new_order)
    Lets a row reference created by the proxy object constructor know that the model emitted the "rows_reordered" signal.

## Detailed Description

A GtkTreeRowReference C++ wrapper class.

A TreeRowReference can be used to point to a node in a model, so long as it exists. The row reference will monitor all signals emitted by the model and update the node path appropriately.

## Constructor & Destructor Documentation

Inti::Gtk::TreeRowReference::TreeRowReference | ( | TreeModel & | model,
|  | const TreePath & | path
| ) |

  | Constructs a row reference based on path. Parameters:
  model | A TreeModel.
  path | A valid TreePath to monitor.
This reference will keep pointing to the node pointed to by path, so long as it exists. It listens to all signals emitted by model, and updates it's path appropriately.

Inti::Gtk::TreeRowReference::TreeRowReference | ( | G::Object & | proxy,
|  | TreeModel & | model,
|  | const TreePath & | path
| ) |

  | Constructs a row reference based on path. You do not need to use this constructor.. Parameters:
  proxy | A proxy G::Object.
  model | A TreeModel.
  path | A valid TreePath to monitor.
You do not need to use this constructor. The row reference will keep pointing to the node pointed to by path, so long as it exists. However, unlike references created with the other constructors, it does not listen to the model for changes. The creator of the row reference must do this explicitly using inserted(), deleted() and reordered(). This must be called once per signal per proxy. This type of row reference is primarily meant for use when you need to carefully monitor exactly when a row reference updates itself. It is not generally needed by most applications.

Inti::Gtk::TreeRowReference::TreeRowReference | ( | GtkTreeRowReference * | reference | ) | `[explicit]`

  | Constructs a row reference from an existing GtkTreeRowReference. Parameters:
  reference | A pointer to a GtkTreeRowReference.
The reference can be a newly created GtkTreeRowReference or an existing GtkTreeRowReference. The TreeRowReference object created is a temporary object. It doesn't take over the ownership of GtkTreeRowReference and GtkTreeRowReference is not freed by the destructor.

Inti::Gtk::TreeRowReference::TreeRowReference | ( | GtkTreeRowReference * | reference,
|  | bool | copy
| ) |

  | Constructs a row reference from an existing GtkTreeRowReference. Parameters:
  reference | A pointer to a GtkTreeRowReference.
  copy | Whether the TreePath object should make a copy of GtkTreePath or not.
The reference can be a newly created GtkTreeRowReference or an existing GtkTreeRowReference. If copy is true TreeRowReference will make a copy of GtkTreeRowReference. If copy is false TreeRowReference wont make a copy but instead takes over the ownership of GtkTreeRowReference. Either way, the destructor will free GtkTreeRowReference when the TreeRowReference object is destroyed. This constructor is used by G::Boxed::wrap() to wrap GtkTreeRowReference objects in a C++ wrapper.

Inti::Gtk::TreeRowReference::TreeRowReference | ( | const TreeRowReference & | src | ) |

  | Copy constructor. Parameters:
  src | The source tree row reference.

## Member Function Documentation

void Inti::Gtk::TreeRowReference::deleted | ( | const G::Object & | proxy,
|  | const TreePath & | path
| ) | `[static]`

  | Lets a row reference created by the proxy object constructor know that the model emitted the "row_deleted" signal. Parameters:
  proxy | A G::Object.
  path | The path position that was deleted.

Pointer<TreePath> Inti::Gtk::TreeRowReference::get_path | ( |  | ) | const

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

void Inti::Gtk::TreeRowReference::inserted | ( | const G::Object & | proxy,
|  | const TreePath & | path
| ) | `[static]`

  | Lets a row reference created by the proxy object constructor know that the model emitted the "row_inserted" signal. Parameters:
  proxy | A G::Object.
  path | The row position that was inserted.

TreeRowReference& Inti::Gtk::TreeRowReference::operator= | ( | const TreeRowReference & | src | ) |

  | Assignment operator. Parameters:
  src | The source tree row reference.

void Inti::Gtk::TreeRowReference::reordered | ( | const G::Object & | proxy,
|  | const TreePath & | path,
|  | const TreeIter & | iter,
|  | int * | new_order
| ) | `[static]`

  | Lets a row reference created by the proxy object constructor know that the model emitted the "rows_reordered" signal. Parameters:
  proxy | A G::Object.
  path | The parent path of the reordered signal.
  iter | The iter pointing to the parent of the reordered row.
  new_order | The new order of rows.

bool Inti::Gtk::TreeRowReference::valid | ( |  | ) | const

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