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`	`GtkTreeIter`
	The new `GtkTreeIter` to set to the parent.
	The argument will be set by the function.
	The data is owned by the caller of the function.
`child`	`GtkTreeIter`
	The `GtkTreeIter`
	The data is owned by the caller of the function.

Return value

Returns:	`gboolean`
	`TRUE`, if `iter` is set to the parent of `child`.
