Synopsis

class gtk.TreeRowReference(gobject.GBoxed):
    gtk.TreeRowReference(model, path)
    def get_path()
    def get_model()
    def valid()
    def copy()
    def free()

Description

Note

This object is available in PyGTK 2.4 and above.

A gtk.TreeRowReference is an object that points to a row in a gtk.TreeModel similar to a gtk.TreeIter. A gtk.TreeRowReference, unlike a gtk.TreeIter, maintains a persistent reference in spite of changes in the model.

Constructor

    gtk.TreeRowReference(model, path)

`model` :	a `gtk.TreeModel`
`path` :	a valid tree path to monitor
Returns :	a `gtk.TreeRowReference`, or `None`

Note

This constructor is available in PyGTK 2.4 and above.

Creates a row reference pointing to the treemodel row specified by model and path. This reference will continue pointing to the node in spite of changes in model. It listens to all signals emitted by model, and updates its path appropriately. If path isn't a valid path in model, None is returned.

Methods

gtk.TreeRowReference.get_path

    def get_path()

Returns :

A current path, or None.

Note

This method is available in PyGTK 2.4 and above.

The get_path() method returns the path that the row reference currently points to, or None if the path pointed to is no longer valid.

gtk.TreeRowReference.get_model

    def get_model()

Returns :

the model, or None.

Note

This method is available in PyGTK 2.8 and above.

The get_model() method returns the model that the row reference currently monitors, or None if the model is not set.

gtk.TreeRowReference.valid

    def valid()

Returns :

True if the row reference points to a valid path.

Note

This method is available in PyGTK 2.4 and above.

The valid() method returns True if the row reference is not None and refers to a current valid path.

gtk.TreeRowReference.copy

    def copy()

Returns :

a copy of the row reference

Note

This method is available in PyGTK 2.4 and above.

The copy() method returns a copy of the tree row reference.

gtk.TreeRowReference.free

    def free()

Note

This method is available in PyGTK 2.4 and above.

Warning

This method is deprecated and should not be used since it may crash your application.

The free() method frees the tree row reference. The row reference may be None.
