本课题设计的数控系统可定制界面是以QT为平台,采用脚本程序定制界面的功能来实现。包括人机界面的设计与构建,QT界面加载器和脚本引擎的扩展,以及底层接口主程序的实现等;同时在QT图形组件类的基础上构建了数控系统专用的图形组件类库...本课题设计的数控系统可定制界面是以QT为平台,采用脚本程序定制界面的功能来实现。包括人机界面的设计与构建,QT界面加载器和脚本引擎的扩展,以及底层接口主程序的实现等;同时在QT图形组件类的基础上构建了数控系统专用的图形组件类库,是实现界面可定制性的基础。该方法充分利用了QT在GUI(Graphical User Interface,图形用户界面)设计方面的优势以及新增的支持脚本功能模块,使定制人机界面的过程变得简便快捷。展开更多
"How do the rescue helicopters find out an optimized path to arrive at the site of a disaster as soon as possible?" or "How are the flight procedures over mountains and plateaus simulated?" and so ..."How do the rescue helicopters find out an optimized path to arrive at the site of a disaster as soon as possible?" or "How are the flight procedures over mountains and plateaus simulated?" and so on.In this paper a script language on spatial moving objects is presented by abstracting 3D spatial moving objects' behavior when implementing moving objects simulation in 3D digital Earth scene,which is based on a platform of digital China named "ChinaStar".The definition of this script language,its morphology and syntax,its compiling and mediate language generating,and the behavior and state control of spatial moving objects are discussed emphatically.In addition,the language's applications and implementation are also discussed.展开更多
