* GtkPlacesView:
*
* GtkPlacesView is a 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.
