The Gtk::TreeView and models should allow us to manage and maintain deeply nested tree structures automatically. But there are times when the intent of a tree view is only to give us a visual representation of some fixed or permanent tree layout. In that case we have to load the data at the program start up time.
-Loading initial values into a tree store may become a daunting task for large tree hierarchies. We usually can help ourselves with some kind of organized structure, most likely a nicely laid array. Following is such an example. For instance we can design a table where the "INDEX" and "PARENT" columns define the hierarchy:
