摘　　要：研究了跨平台类库Qt的状态转换机制。介绍了QState类和QStateMachine类,对状态机中的历史状态、复合状态、平行状态做了详解,并给出了关键代码。在软件开发中,应用Qt状态转换机制能够简化编程过程。经过实际的软件研发,结果表明,在开发交互式应用程序和动画应用程序时应用Qt状态转换机制更能提高编程效率。The state transition mechanism of cross-platform class library Qt is researched. The classes of QState and QStateMachine are introduced. The historical states, compound states and parallel states are recounted. The pivotal code is given. With the use of state transition mechanism of Qt, programming process can be simplified in developing software. The practical exploitation of the software shows that the use of state transition mechanism of Qt can improve the efficiency of programming while the interactive application program and animation application program are developed.

关 键 词：QT QState 状态机 状态转换机制 编程过程简化
