Function

GtkTreeRowReferencenew_proxy

Declaration [src]

GtkTreeRowReference*
gtk_tree_row_reference_new_proxy (
  GObject* proxy,
  GtkTreeModel* model,
  GtkTreePath* path
)

Description [src]

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.

Parameters

proxy GObject
 

A proxy GObject.

 The data is owned by the caller of the function.
model GtkTreeModel
 

A GtkTreeModel.

 The data is owned by the caller of the function.
path GtkTreePath
 

A valid GtkTreePath-struct to monitor.

 The data is owned by the caller of the function.

Return value

Returns: GtkTreeRowReference
 

A newly allocated GtkTreeRowReference, or NULL.

 The caller of the function takes ownership of the data, and is responsible for freeing it.
