/**
 * SECTION:gtkplacessidebar
 * @Short_description: Sidebar that displays frequently-used places in the file system
 * @Title: GtkPlacesSidebar
 * @See_also: #GtkFileChooser
 *
 * #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.

/* These are used when a destination-side DnD operation is taking place.
 * Normally, when a file is being hovered directly over a bookmark,

 * But when a file is being hovered between bookmarks, this means the user
 * may want to create a new bookmark for that file between those bookmarks.
 * In that case, the drop state will be *not* DROP_STATE_NORMAL.
 *
 * When the drop state is FADING_OUT, it means that the user is hovering
 * directly over an existing bookmark and an immediate drop will cause the
 * file being dragged to be dropped on the bookmark, instead of causing
