关于Qt 状态机

 

QStateMachine


    machine->addState(s1);
machine->addState(s2);     //加载状态
    machine->setInitialState(s1);        //设置初始化属性 s1
    machine->start();                      //开始状态

 

QState()

 


s1->assignProperty(ui->pushButton, "text", "Click me");    //当激活状态时, 设置ui->pushButton 的 text 属性, 值为 Click me
s2->addTransition(ui->pushButton, SIGNAL(clicked()), s2);      //激活条件,当ui->pushButton clicked的时候, s1状态转换到s2


 

  machine = new QStateMachine;


    s1 = new QState();
    s1->assignProperty(ui->pushButton, "text", "Click me");    //设置pushButton text 的属性为 Click me

    s2 = new QState();
    s1->addTransition(ui->pushButton, SIGNAL(clicked()), s2);      //激活条件  点击clicked后, 出发转到s2
    s2->assignProperty(ui->pushButton, "text", "state2");              //s2 做的事

    machine->addState(s1);
    machine->addState(s2);
    machine->setInitialState(s1);        //初始化属性 s1
    machine->start();                      //开始s1
