具体代码实现

    QPainter painter(this);
    QPen pen;
    QBrush brush;

    //背景绘制
    QPixmap pix;
    pix.load("C:\\Users\\23999\\Desktop\\tool-mastar\\stylle_toolV1.4\\img\\background.jpg");//背景图片位置
    painter.drawPixmap(0, 0, 600, 368, pix);//位置大小以及pix配置传入，画图

    //蛇的配置
    pen.setColor(Qt::green);
    brush.setColor(Qt::darkGreen);
    brush.setStyle(Qt::SolidPattern);
    painter.setPen(pen);     //送笔
    painter.setBrush(brush); //送笔刷
    painter.drawRect(snake[0]);
    for (int i = 1; i < snake.length(); i++)
    {
        painter.drawRect(snake[i]);
    }

    //食物的配置
    pen.setColor(Qt::blue);
    brush.setColor(Qt::darkBlue);
    brush.setStyle(Qt::SolidPattern);
    painter.setPen(pen);                //送笔
    painter.setBrush(brush);            //送笔刷
    painter.drawEllipse(rewardNode[0]); //圆形
