The active_display frame template is an OpenROAD core library template that creates a standard dialog containing a set of menu and toolbar buttons. It also contains the basic code to drive an object-based display generated using the Display from User Class facility in the Frame Editor. It supports retrieval and step-through of all records in the database that map to the specified user class, and lets you edit and delete these and related records.

Almost all the actual code executed resides in the user class RequestManager, which also is present in the core application; the event code in the frame makes appropriate calls to RequestManager functions. For more information about the RequestManager user class, see the Language Reference Guide.

Although the base functionality is reliable and sophisticated, developers may want to further customize the code. Instructions to enable you to extend the code in this way are provided in How You Can Customize the Built-in Active Display Code.
