56 * Behaviour:
57 *
58 * - Clicking Save or pressing Return:
59 * - Emits 'save_to_file',
60 * - Emits 'saved_to_uri' (with the same pathname),
61 * - Destroys the widget.
62 *
63 * - Clicking Cancel or pressing Escape:
64 * - Destroys the widget.
65 *
66 * - Dragging the data somewhere:
67 * - Will either emit 'save_to_file' or get the selection,
68 * - Emits 'saved_to_uri' (possibly with a NULL URI),
69 * - Destroys the widget.
70 *
71 * - Clicking Discard:
72 * - Emits 'saved_to_uri' with a NULL URI,
73 * - Destroys the widget.
74 *
75 * To clarify: 'saved_to_uri' indicates that the save was successful. A
76 * NULL URI just means that the data was saved to another application rather
77 * than a fixed address. Data should only be marked unmodified when
78 * saved_to_uri is called with a non-NULL URI.
79 *
80 * Discard is a bit like a successful save to a null device. The data should
81 * be discarded when saved_to_uri is called, whatever URI is set to.
82 *
83 *
84 * Signals:
85 *
86 * gint save_to_file (GtkSavebox *savebox, const gchar *pathname)
87 * Save the data to disk using this pathname. Return GTK_XDS_SAVED
88 * on success, or GTK_XDS_SAVE_ERROR on failure (and report the error
89 * to the user somehow). DO NOT mark the data unmodified or change
90 * the pathname for the file - this might be a scrap file transfer.
91 *
92 * void saved_to_uri (GtkSavebox *savebox, const gchar *uri)
93 * The data is saved. If 'uri' is non-NULL, mark the file as unmodified
94 * and update the pathname/uri for the file to the one given.
95 * The URI is UTF-8 (not escaped).
