gtk.TreeRowReference an object maintaining a persistent reference to a gtk.TreeModel row (new in PyGTK 2.4) gtk.TreeRowReference gobject.GBoxed gtk.TreeRowReference model path get_path get_model valid copy free 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. gtk.TreeRowReference model path model : a gtk.TreeModel path : a valid tree path to monitor Returns : a gtk.TreeRowReference, or None 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. get_path Returns : A current path, or None. 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 The get_path() method returns the path that the row reference currently points to, or None if the path pointed to is no longer valid. get_model Returns : the model, or None. 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. valid Returns : True if the row reference points to a valid path. 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. copy Returns : a copy of the row reference This method is available in PyGTK 2.4 and above. The copy() method returns a copy of the tree row reference. free This method is available in PyGTK 2.4 and above. 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.
