/* Lists/Settings
|
||
* #Keywords: GtkListItemFactory, GListModel
|
||
*
|
||
* This demo shows a settings viewer for GSettings.
|
||
*
|
||
* It demonstrates how to implement support for trees with GtkListView.
|
||
* It also shows how to set up sorting and filtering for columns in a
|
||
* GtkColumnView.
|
||
*
|
||
* It also demonstrates different styles of list. The tree on the left
|
||
* uses the .navigation-sidebar style class, the list on the right uses
|
||
* the .data-table style class.
