/**
 * Native dialogs are platform dialogs that don't use #GtkDialog or
 * #GtkWindow. They are used in order to integrate better with a
 * platform, by looking the same as other native applications and
 * supporting platform specific features.
 * 
 * The #GtkDialog functions cannot be used on such objects, but we
 * need a similar API in order to drive them. The #GtkNativeDialog
 * object is an API that allows you to do this. It allows you to set
 * various common properties on the dialog, as well as show and hide
 * it and get a #GtkNativeDialog::response signal when the user finished
 * with the dialog.
 * 
 * There is also a gtk_native_dialog_run() helper that makes it easy
 * to run any native dialog in a modal way with a recursive mainloop,
 * similar to gtk_dialog_run().
