Virtual Method

GtkTreeModeliter_parent

Declaration [src]

gboolean
iter_parent (
  GtkTreeModel* tree_model,
  GtkTreeIter* iter,
  GtkTreeIter* child
)

Description [src]

Sets iter to be the parent of child.

If child is at the toplevel, and doesn’t have a parent, then iter is set to an invalid iterator and FALSE is returned. child will remain a valid node after this function has been called.

iter will be initialized before the lookup is performed, so child and iter cannot point to the same memory location.

Parameters

iter

Type: GtkTreeIter

The new GtkTreeIter-struct to set to the parent.

The argument will be set by the function.

The returned data is owned by the instance.

child

Type: GtkTreeIter

The GtkTreeIter-struct.

The data is owned by the caller of the method.

Return value

Type: gboolean

TRUE, if iter is set to the parent of child.
