Object-widgets have all the advantages of objects in general. In
particular, encapsulation and a documented interface are important
features. With a standard widget program, you basically have to give
away your tlb widget identifier for another routine to interact with
you. At which point, the interacting program can do anything they want
to you. But an object-widget can publish an interface of actions it can
take, properties that can be examined, etc. This makes working with
object-widgets much easier and the code that interacts with them much
easier to maintain.
