Release 10.1A: OpenEdge Development:
Progress Dynamics Advanced Development

Customizing classes for all objects

To change the behavior of all the objects that belong to an existing class, you should use the Class Maintenance tool to customize and not extend the class. For more information about customizing classes, see the "Customizing classes for some objects" section. For more information about using the Class Maintenance tool, see the "Class Maintenance tool" section.

The class being customized does not need to be a class that has objects directly associated with it, such as the DynView class that contains dynamic viewers. The class being customized can be any class in the class hierarchy. The higher up in the class hierarchy where customizations are made results in more classes, and therefore objects, being affected.

Caution: It is possible to extend the Progress Dynamics behavior by inserting a class between two classes that come with the product. However, this is not the recommended approach as these relationships are overwritten when you install a new version of the product.
