The Design And Implementation Of The Application User Interface Framework Based On DirectUI

With the development of software and hardware industry, the requirements of user interface are increasingly high. Even more, enterprises put the user experience to a strategic position. While, the traditional UI develop concept can’t meet the demand of the current product. DirectUI, with its characteristics of flexibility, convenience and friendly, has gradually become the mainstream of the new interface development technology. At present, there isn’t a mature UI Framework based on DirectUI. And, the count of DirectUI researches is little. In this background, this paper has deeply studied the Direct UI technology, and described the design and implementation of the User Interface Framework Based on Direct UI.At first, this paper discussed the background and the significance of the subject,and the overseas and domestic research status of the Direct UI. Then, the message mechanism was deeply researched and the XML, Graphical Library technology were presented, which laid a technical foundation of the implementation of the UI Framework based on Direct UI. Afterwards, the architecture design of the Framework was explained and the subsystem partition of the system was carried out. According to the demands of the Framework, this paper formulated the DirectUI Interface Markup Language, which was used to describe the UI, established the format of the configuration file using the Direct UI Interface Markup Language, designed and implemented the Interface Parsing Engine, Rendering Engine, the Message Distribution System, Resource Manager System, Script Engine, VirtualControl Library and the Dui Designer. Finally, applied the Framework to the ICT project, which verified the feasibility of the Framework. Then from the aspects of interface performance and security, verified the superiority of the UI Framework Based on DirectUI.
