/* Lists/Settings v2
* #Keywords: GtkListHeaderFactory, GtkSectionModel
*
* This demo shows a settings viewer for GSettings.
*
* It demonstrates how to implement support for sections with GtkListView.
*
* It also shows how to quickly flatten a large tree of items into a list
* that can be filtered to find the items one is looking for.
