With ObjectWindows designed using multiple inheritance, you can derive new classes that inherit the behavior of more than one class.

Such "mixed" behavior is different from the behavior you get from single inheritance derivation. Instead of inheriting the behavior of the base class and being able to add to and change it, you're inheriting and combining the behavior of several classes.

As with single inheritance derivation, you can add new members and override inherited ones to change the behavior of your new class.
