A Frame is a class that implements the functionality of a frame. It might have an interface and inherits a Main method that is executed on a printframe LDL+ command. The ‘Main’ method might be overridden. The Class functions as a report frame by providing a main method to override and restricting properties to those applicable to reports. When an attribute of this class is invoked, the main method is executed before printing the presentation. The default window is Members.

A Frame can be owned by any class, including another Frame and can be both, a class definition and an instance.
