为什么第一个动画组被忽略了呀？  要让两个动画组串着运行怎么办呀？ [复制链接]

    QPushButton button1("Animated Button");
    button1.show();

    button2.show();
    //按钮部件1的动画
    QPropertyAnimation *animation1 = new QPropertyAnimation(&button1, "geometry");
    animation1->setDuration(2000);
    animation1->setStartValue(QRect(250, 0, 100, 30));
    animation1->setEndValue(QRect(250, 300, 100, 30));
    animation1->setEasingCurve(QEasingCurve::OutBounce);
    //按钮部件2的动画
    QPropertyAnimation *animation2 = new QPropertyAnimation(&button2, "geometry");
    animation2->setDuration(2000);
    animation2->setStartValue(QRect(400, 0, 100, 30));
    animation2->setEndValue(QRect(400, 300, 100, 30));
     animation2->setEasingCurve(QEasingCurve::OutBounce);
    //并行动画组
    QParallelAnimationGroup group;
    group.addAnimation(animation1);
    group.addAnimation(animation2);
    group.start();

    QPropertyAnimation *animation3 = new QPropertyAnimation(&button1, "geometry");
    animation3->setDuration(2000);
    animation3->setStartValue(QRect(250,300, 100, 30));
    animation3->setEndValue(QRect(450, 300, 100, 30));
    animation3->setEasingCurve(QEasingCurve::OutBounce);
    //按钮部件2的动画
    QPropertyAnimation *animation4 = new QPropertyAnimation(&button2, "geometry");
    animation4->setDuration(2000);
    animation4->setStartValue(QRect(400,300, 100, 30));
    animation4->setEndValue(QRect(600, 300, 100, 30));
     animation4->setEasingCurve(QEasingCurve::OutBounce);

     QParallelAnimationGroup group1;
     group1.addAnimation(animation3);
     group1.addAnimation(animation4);
     group1.start();


    return app.exec();
}

将第一个动画的结束信号与第二个动画的开始方法连接起来。
