Implementation Of The Control Set And Their Scripted Technology

The interactive features of the embedded products has been growing emphasis on, thegraphical user interface is particularly important as the bridge of the human-computerinteraction. It propose new requirements to the control set of the graphic system, while thecontrols set meet to the lightweight, efficient, beautiful and easy to maintain, also improvethe development efficiency of using the control set to develop graphical user interface,shorten the development cycle. By introducing object system and scripting technologiesfor the control set, combined with the scripting language`s feature of easy to understand,flexible, fast development and so on, achieved a set of a scripting language based controlset. Greatly improve the efficiency of the graphical user interface development.The control set is based on object system, was developed by object-oriented thinking.Object system provides a C language-based object-oriented mechanism for the control set.Achieved the class structure designed, the lifecycle management the signal mechanismand the attribute management functions of the object. Completed object abstraction,encapsulation, constructor and destructor mechanism, the reference count management.The control set provides a controls inheritance hierarchy and control managementsystem. The subclass inherits all the functionality of the parent class and extends thefunctions on the basis of the parent class. The inheritance system reduces the complexityof the extension of the control set, do not repeat the same functionality. Managementsystem including the focus management of controls, event handling mechanism, controlthe display control, provides a protection for the control`s human-computer interactionfunction, give the user a better product experience.Through a combination of controls and scripting module, scripted control set, makes itpossible to use JSON script language describe control objects and their attributes, furtherdescript of the entire graphical user interface. Greatly improving the efficiency of thedevelopment of the graphical user interface, reduce the difficulty of maintenance of thegraphical user interface.
