【Abstract】 With the improvement of hardware quality of embedded device,embedded system’s demand for GUI has increasingly enhanced,and status of embedded GUI becomes extraordinarily important.CAR component technique is the key technique of "elastos" which has the independent copyright of China.The embedded GUI system based on CAR(Carefree Application Run-Time) component technique is very flexible and efficient.The system adopts modularized CAR component technique and the special callback-event mechanism which is used for dealing with input and output of events,so it could realize man-machine conversation interface perfectly.更多还原
