Modifying a Class Definition
Once you have created a class, you can modify it. Changes made to a class affect all the subclasses and all the objects based on this class. You can add an enhancement to a class or fix a bug in the class, and all the subclasses and objects based on the class will inherit the change.
To modify a class in the Project Manager
- Select the class you want to modify.
- Choose Modify.
The Class Designer opens.
You can also modify a visual class definition with the MODIFY CLASS command.
Caution Don't change the Name property of a class if the class is already being used in any other application components. Otherwise, Visual FoxPro will not be able to locate the class when needed.
