| In recent years, the digitization and networking has become the developing directions of electrical appliances, as the core technique of informative electrical appliances, embedded database has become the host spot of study in the field of database technology. With the support of GUI, the design of UI is simple and flexible, general maintenance and the upgrade of the request of user is convenient. Now, popular RTOS generally do not provider GUI, or the use of GUI module which is not convenient, so the development of GUI become the majority choice for embedded devices.Embedded GUI system is used to develop UI directly, so this paper described the realization of the package of tools detailedly and completely. The article starts by describing associated with the hardware-driven GUI interface design tool, the code related to the specific platform focus on two documents, this is the bottom of hierarchical design, including the designing of font and the realization of GDI system, GDI system is a basic map algorithm set, it is the most basic graphics commands. Secondly, system uses object-oriented design, provided a series default control class, user can develop graphic interface conveniently and quickly; meanwhile, supporting the mapping function, user can develop their unique graphic interface according to their needs easily. Because of their direct application-oriented, it is the whole of the second GUI layer, apart from the GUI interface, GUI design tool also provides a lot of animation, making the development of the graphical user interface is more beautiful.The author of this paper took part in the development of the embedded GUI system based on the digital STB, and then finished this paper. This paper introduces the whole GUI system design and implementation details, then specific examples of application platform, introduced the features of embedded platform and the realization of user interface. Finally, the system discusses the important features and innovations deeply. |
