Copies a #GtkTreeRowReference.
Free's reference. reference may be %NULL.
Returns %TRUE if the reference is non-%NULL and refers to a current valid
path.
Creates a row reference based on path. 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 its path appropriately. If path
isn't a valid path in model, then %NULL is returned.
You do not need to use this function. Creates a row reference based on
path. This reference will keep pointing to the node pointed to by path,
so long as it exists. If path isn't a valid path in model, then %NULL is
returned. However, unlike references created with
gtk_tree_row_reference_new(), it does not listen to the model for changes.
The creator of the row reference must do this explicitly using
gtk_tree_row_reference_inserted(), gtk_tree_row_reference_deleted(),
gtk_tree_row_reference_reordered().
These functions must be called exactly once per proxy when the
corresponding signal on the model is emitted. This single call
updates all row references for that proxy. Since built-in GTK+
objects like #GtkTreeView already use this mechanism internally,
using them as the proxy object will produce unpredictable results.
Further more, passing the same object as model and proxy
doesn't work for reasons of internal implementation.
This type of row reference is primarily meant by structures that need to carefully monitor exactly when a row reference updates itself, and is not generally needed by most applications.
A proxy #GObject
A #GtkTreeModel
A valid #GtkTreePath to monitor
Lets a set of row reference created by gtk_tree_row_reference_new_proxy() know that the model emitted the "rows_reordered" signal.
A #GObject
The parent path of the reordered signal
The iter pointing to the parent of the reordered
The new order of rows
Creates a row reference based on
path. This reference will keep pointing to the node pointed to bypath,so long as it exists. It listens to all signals emitted bymodel,and updates its path appropriately. Ifpathisn't a valid path inmodel,then %NULL is returned.
