1、新建QT GUI，取消创建界面，基类选择“QWidget”

2、构造函数中：

QProgressBar *progress[4];
        progress[0] = new QProgressBar(this);
        progress[0]->setMinimum(0);
        progress[0]->setMaximum(100);
        progress[0]->setValue(50);  //设置默认值
        progress[0]->setOrientation(Qt::Horizontal);  //水平放置
    
        progress[1] = new QProgressBar(this);
        progress[1]->setMinimum(0);
        progress[1]->setMaximum(100);
        progress[1]->setValue(70);
        progress[1]->setOrientation(Qt::Horizontal);
        progress[1]->setInvertedAppearance(true); //反转方向
    
        progress[2] = new QProgressBar(this);
        progress[2]->setMinimum(0);
        progress[2]->setMaximum(100);
        progress[2]->setValue(70);
        progress[2]->setOrientation(Qt::Vertical); //垂直放置
    
        progress[3] = new QProgressBar(this);
        progress[3]->setMinimum(0);
        progress[3]->setMaximum(100);
        progress[3]->setValue(70);
        progress[3]->setOrientation(Qt::Vertical);
        progress[3]->setInvertedAppearance(true);
    
        progress[0]->setGeometry(10,30, 300, 30);
        progress[1]->setGeometry(10,70, 300, 30);
    
        progress[2]->setGeometry(400,30, 30, 300);
        progress[3]->setGeometry(440,30, 30, 300);
