 * @Title: GtkPlacesSidebar
 * @Short_description: The locations sidebar for the file selection widget
 *
 * #GtkPlacesSidebar is a widget that displays a list of frequently-used places in the
 * file system:  the user’s home directory, the user’s bookmarks, and volumes and drives.
 * This widget is used as a sidebar in #GtkFileChooser and may be used by file managers
 * and similar programs.
 *
 * The places sidebar displays drives and volumes, and will automatically mount
 * or unmount them when the user selects them.
 *
 * Applications can hook to various signals in the places sidebar to customize
 * its behavior.  For example, they can add extra commands to the context menu
 * of the sidebar.
 *
 * While bookmarks are completely in control of the user, the places sidebar also
 * allows individual applications to provide extra shortcut folders that are unique
 * to each application.  For example, a Paint program may want to add a shortcut
 * for a Clipart folder.  You can do this with gtk_places_sidebar_add_shortcut().
 *
 * To make use of the places sidebar, an application at least needs to connect
 * to the #GtkPlacesSidebar::open-location signal.  This is emitted when the
 * user selects in the sidebar a location to open.  The application should also
 * call gtk_places_sidebar_set_location() when it changes the currently-viewed
 * location.
 *
 * # CSS nodes
 *
 * GtkPlacesSidebar uses a single CSS node with name placessidebar and style
 * class .sidebar.
 *
 * Among the children of the places sidebar, the following style classes can
 * be used:
 * - .sidebar-new-bookmark-row for the 'Add new bookmark' row
 * - .sidebar-placeholder-row for a row that is a placeholder
 * - .has-open-popup when a popup is open for a row
 */

/* These are used when a destination-side DND operation is taking place.
 * Normally, when a common drag action is taking place, the state will be
 * DROP_STATE_NEW_BOOKMARK_ARMED, however, if the client of GtkPlacesSidebar
 * wants to show hints about the valid targets, we sill set it as
 * DROP_STATE_NEW_BOOKMARK_ARMED_PERMANENT, so the sidebar will show drop hints
 * until the client says otherwise

 * which needs the data from the drag so we cannot free the drag data here.
 * So now one could think we could just do nothing here, and wait for
 * drag-end or drag-cancel signals and just stop_drop_feedback there. But that
 * is also not true, since when the drag comes from a different widget than the
 * sidebar, when the drag stops the last drag signal we receive is drag-leave.
 * So here what we will do is restore the state of the sidebar as if no drag
 * is being done (and if the application didn't request for permanent hints with
 * gtk_places_sidebar_show_drop_hints) and we will free the drag data next time
 * we build new drag data in drag_data_received.
