/* Tree View/Tree Store

 *

 * The GtkTreeStore is used to store data in tree form, to be

 * used later on by a GtkTreeView to display it. This demo builds

 * a simple GtkTreeStore and displays it. If you're new to the

 * GtkTreeView widgets and associates, look into the GtkListStore

 * example first.
