+ * @Title: GtkAppChooserDialog
+ * @Short_description: An application chooser dialog
+ *
+ * #GtkAppChooserDialog shows a #GtkAppChooserWidget inside a #GtkDialog.
+ *
+ * Note that #GtkAppChooserDialog does not have any interesting methods
+ * of its own. Instead, you should get the embedded #GtkAppChooserWidget
+ * using gtk_app_chooser_dialog_get_widget() and call its methods if
+ * the generic #GtkAppChooser interface is not sufficient for your needs.
+ *
+ * To set the heading that is shown above the #GtkAppChooserWidget,
+ * use gtk_app_chooser_dialog_set_heading().
