Description

----------------------------------- User_Return_Callback_With_Setup -- ----------------------------------- This package is basically the same as User_Return_Callback, except that an extra function (Setup) is called after a handler has been connected. Typical usage is to automatically call Add_Watch (see below) in case the User_Type is (or contains) widgets.
