QtinUse - UI & System Design Challenges for the NxG Lighting Tool
summary
DreamWorks migrates a 16-year proprietary Xlib toolkit (Phooey) into Qt by refactoring low-level X calls, creating an opt-in Qt integration and a hybrid event loop that inspects events first, preserves delicate FooI timers, and bottlenecks API calls. New next-generation lighting and animation tools are pure Qt, use QGraphicsView to drive spreadsheets and views that handle hundreds of thousands of objects and particle vertices selectable individually, and are already working in production.
