tree 如何取消选择

[prosteven2]

tree view，单击item，可以展开，并加亮显示。这是默认行为。

现在，如果通过调用函数gtk_tree_selection_select_path选择另一个item ，如何使当前选中的item不再加亮显示？

以下方法无效，不能取消原先选中item的加亮状态：

GtkTreeSelection* sel = gtk_tree_view_get_selection( GTK_TREE_VIEW(dir_tree_view_widget) );
gtk_tree_selection_unselect_path( sel, current_dir_tree_path );

图解：

root
|
|-item1
|
|-item2
|
...

选中item1，调用函数gtk_tree_selection_select_path选中item2， item1如何取消选中状态，不再加亮显示？
