Participants

• AbstractFactory (WidgetFactory)

• declares an interface for operations that create abstract product objects.
• ConcreteFactory (MotifWidgetFactory, PMWidgetFactory)

• implements the operations to create concrete product objects.
• AbstractProduct (Window, ScrollBar)

• declares an interface for a type of product object.
• ConcreteProduct (MotifWindow, MotifScrollBar)

• defines a product object to be created by the corresponding concrete factory.
• implements the AbstractProduct interface.
• Client

• uses only interfaces declared by AbstractFactory and AbstractProduct classes.
