/**
 * #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

	/**
	 * The places sidebar emits this signal when the user invokes a contextual
	 * popup on one of its items. In the signal handler, the application may
	 * add extra items to the menu as appropriate. For example, a file manager
	 * may want to add a "Properties" command to the menu.
	 *
	 * It is not necessary to store the @selected_item for each menu item;
	 * during their callbacks, the application can use gtk_places_sidebar_get_location()
	 * to get the file to which the item refers.
	 *
	 * The @selected_item argument may be %NULL in case the selection refers to
	 * a volume. In this case, @selected_volume will be non-%NULL. In this case,
	 * the calling application will have to g_object_ref() the @selected_volume and
	 * keep it around to use it in the callback.
	 *
	 * The @container and all its contents are destroyed after the user
	 * dismisses the popup. The popup is re-created (and thus, this signal is
	 * emitted) every time the user activates the contextual menu.
	 *
	 * Before 3.18, the @container always was a #GtkMenu, and you were expected
	 * to add your items as #GtkMenuItems. Since 3.18, the popup may be implemented
	 * as a #GtkPopover, in which case @container will be something else, e.g. a
	 * #GtkBox, to which you may add #GtkModelButtons or other widgets, such as
	 * #GtkEntries, #GtkSpinButtons, etc. If your application can deal with this
	 * situation, you can set #GtkPlacesSidebar::populate-all to %TRUE to request
	 * that this signal is emitted for populating popovers as well.
	 *
	 * Params:
	 *     container = a #GtkMenu or another #GtkContainer
	 *     selectedItem = #GFile with the item to which the popup should refer, or #NULL in the case of a @selected_volume.
