针对嵌入式多任务GUI系统需要非常强的灵活性、可移植性和可伸缩性的特点,提出一种通用解决方案;采用层次化、模块化和面向对象的设计思想,给出了GUI的体系结构,并对多任务GUI设计中的多任务调度策略及管理、消息驱动机制、桌面及窗口管理和对象树等关键技术进行了研究。该解决方案的原型已经成功应用于我国自主产权的实时操作系统DeltaOS中。 For embedded multi-tasking GUI system needs very strong flexibility, portability and scalability features, propose a universal solution; using hierarchical, modular and object-oriented design ideas, gives the GUI system Structure and multi-task scheduling strategy and management of multitasking GUI design, message-driven mechanism, desktop and window management and object tree and other key technologies were studied. The prototype of this solution has been successfully applied to DeltaOS, a real-time operating system of our country.
