This chapter describes OpenROAD system classes and their associated attributes and methods. By using these attributes and methods, you can manipulate OpenROAD application components from your scripts and procedures.

The system classes include all OpenROAD application components, such as frames, forms, menus, field menus, and menu items. In addition, OpenROAD provides system classes that are used for classification only—known as abstract or abstraction classes in object-oriented programming—such as ActiveField and FieldObject. Such classes begin with a note stating that they are for classification only.
