47  * #GtkPlacesSidebar is a widget that displays a list of frequently-used places in the
48  * file system:  the user’s home directory, the user’s bookmarks, and volumes and drives.
49  * This widget is used as a sidebar in #GtkFileChooser and may be used by file managers
50  * and similar programs.
51  * 
52  * The places sidebar displays drives and volumes, and will automatically mount
53  * or unmount them when the user selects them.
54  * 
55  * Applications can hook to various signals in the places sidebar to customize
56  * its behavior.  For example, they can add extra commands to the context menu
57  * of the sidebar.
58  * 
59  * While bookmarks are completely in control of the user, the places sidebar also
60  * allows individual applications to provide extra shortcut folders that are unique
61  * to each application.  For example, a Paint program may want to add a shortcut
62  * for a Clipart folder.  You can do this with gtk_places_sidebar_add_shortcut().
63  * 
64  * To make use of the places sidebar, an application at least needs to connect
65  * to the #GtkPlacesSidebar::open-location signal.  This is emitted when the
66  * user selects in the sidebar a location to open.  The application should also
67  * call gtk_places_sidebar_set_location() when it changes the currently-viewed
68  * location.
69  * 
70  * # CSS nodes
71  * 
72  * GtkPlacesSidebar uses a single CSS node with name placessidebar and style
73  * class .sidebar.
74  * 
75  * Among the children of the places sidebar, the following style classes can
76  * be used:
77  * - .sidebar-new-bookmark-row for the 'Add new bookmark' row
78  * - .sidebar-placeholder-row for a row that is a placeholder
79  * - .has-open-popup when a popup is open for a row
