  A user interface (UI) framework supports the development of graphical operator controls for the National Ignition Facility (NIF) Integrated Computer Control System (ICCS). The framework simplifies UI coding and ensures consistency for system operators across all NIF subsystems. A comprehensive, layered collection of UIs provides interaction with service-level frameworks, shot automation, and subsystem-specific devices. All user interfaces are written in Java and employ CORBA to interface to other ICCS components. Developers use the framework to compose two major types of user interfaces for broad-views and control panels. Broad-views provide a visual representation of NIF beamlines through interactive schematic drawings. Control panels present status and control at the device level. The UI framework provides a suite of display components that standardize user interaction through data entry behaviors, common connection and threading mechanisms, and a common appearance. With these components, developers can address pattern usability issues in the facility when needed. The UI framework helps developers create consistent and easy-to-understand user interfaces for NIF operators.
