29 * gtk_show_uri:
30 * @screen: (allow-none): screen to show the uri on
31 * or %NULL for the default screen
32 * @uri: the uri to show
33 * @timestamp: a timestamp to prevent focus stealing
34 * @error: a #GError that is returned in case of errors
35 *
36 * A convenience function for launching the default application
37 * to show the uri. Like gtk_show_uri_on_window(), but takes a screen
38 * as transient parent instead of a window.
39 *
40 * Note that this function is deprecated as it does not pass the necessary
41 * information for helpers to parent their dialog properly, when run from
42 * sandboxed applications for example.
43 *
44 * Returns: %TRUE on success, %FALSE on error
45 *
46 * Since: 2.14
47 *
48 * Deprecated: 3.22: Use gtk_show_uri_on_window() instead.

116 * need to install gvfs to get support for uri schemes such as http://
117 * or ftp://, as only local files are handled by GIO itself).
118 * Typical examples are

120 * - `http://www.gnome.org`
121 * - `mailto:me@gnome.org`
122 *
123 * Ideally the timestamp is taken from the event triggering
124 * the gtk_show_uri() call. If timestamp is not known you can take
125 * %GDK_CURRENT_TIME.
