* @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().
