/* Tree View/Tree Store
|
|
*
|
|
* The Gtk.TreeStore is used to store data in tree form, to be
|
|
* used later on by a Gtk.TreeView to display it. This demo builds
|
|
* a simple Gtk.TreeStore and displays it. If you're new to the
|
|
* Gtk.TreeView widgets and associates, look into the Gtk.ListStore
|
|
* example first.
