/**
- * gtk_show_uri_on_window:
+ * gtk_show_uri_full:
* @parent: (allow-none): parent window
* @uri: the uri to show
- * @timestamp: a timestamp to prevent focus stealing
- * @error: a #GError that is returned in case of errors
+ * @timestamp: timestamp from the event that triggered this call, or %GDK_CURRENT_TIME
+ * @cancellable: (allow-none): a #GCancellable to cancel the launch
+ * @callback (allow-none): a callback to call when the action is complete
+ * @user_data: data to pass to @callback
+ * @destroy: destroy notify for @user_data
*
- * This is a convenience function for launching the default application
- * to show the uri. The uri must be of a form understood by GIO (i.e. you
- * need to install gvfs to get support for uri schemes such as http://
+ * This function launches the default application for showing
+ * a given uri.
+ *
+ * The uri must be of a form understood by GIO (i.e. you need
+ * to install gvfs to get support for uri schemes such as http://
* or ftp://, as only local files are handled by GIO itself).
* Typical examples are
* - `file:///home/gnome/pict.jpg`
* - `http://www.gnome.org`
* - `mailto:me@gnome.org`
*
- * Ideally the timestamp is taken from the event triggering
- * the gtk_show_uri_on_window() call. If timestamp is not known you can take
- * %GDK_CURRENT_TIME.
+ * The @callback will be called when the launch is completed.
+ * It should call gtk_show_uri_finish() to obtain the result.
*
* This is the recommended call to be used as it passes information
* necessary for sandbox helpers to parent their dialogs properly.
- *
- * Returns: %TRUE on success, %FALSE on error
