 * @Short_description: Widget that displays persistent drives and manages mounted networks
 * @Title: GtkPlacesView
 * @See_also: #GtkFileChooser
 *
 * #GtkPlacesView is a stock widget that displays a list of persistent drives
 * such as harddisk partitions and networks.  #GtkPlacesView does not monitor
 * removable devices.
 *
 * The places view displays drives and networks, and will automatically mount
 * them when the user activates. Network addresses are stored even if they fail
 * to connect. When the connection is successful, the connected network is
 * shown at the network list.
 *
 * To make use of the places view, an application at least needs to connect
 * to the #GtkPlacesView::open-location signal. This is emitted when the user
 * selects a location to open in the view.
