/* 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.
