Don't worry Rick, various air traffic control systems written in Ada, with safety-critical GUIS, have been running 24x7 for the past 20 years or so, sometimes even longer than that. There was no need for a "standard" graphical framework, only for one that worked. These apps are so specialized anyway that a "standard" would probably have gotten in the way of ergonomy. The system I work on at Eurocontrol is not safety-critical but definitely mission-critical and has had an X11 GUI since circa 1992. Additionally I worked at Barco Avionics a few years ago and rest assured that the safety-critical, hard real-time cockpit displays[1] were quite graphical too, thank you very much. And programmed 99% in Ada and 1% assembly. [1] http://www.barco.com/en/productcategory/18 -- Ludovic Brenta.
