HMI-29-【运动模式】转速表实现及中心油耗仪表实现

​ 今天我要搞得就是中心的这个表，指针的是转速表 中心显示的油耗表。

实现转速表

​ 前面准备工作还是一样，从PS中导出需要的资源文件，并吧资源文件稍微加工下导入到工程中。转速表比速度实现要稍微简单一点，因为这就是一个标准的圆，只需要绘制图片，控制旋转角度即可。代码如下：

void MDS_Center::drawPointer(int angle)
{
    QPainter painter(ui->label_pointer);
    painter.setRenderHint((QPainter::SmoothPixmapTransform));
    painter.setRenderHint(QPainter::HighQualityAntialiasing);
    painter.translate(337,337);
    painter.save();
    painter.rotate(angle);
    painter.drawPixmap((-960),-360,1920,720,QPixmap(":/Sport/Resources/MeterDisplay/Sport/MDSC/pointer.png"));
    painter.drawPixmap(-213,-213,426,426,QPixmap(":/Sport/Resources/MeterDisplay/Sport/MDSC/hu.png"));
    painter.setOpacity(m_shadeOpacity);
    painter.drawPixmap((-960),-360,1920,720,QPixmap(":/Sport/Resources/MeterDisplay/Sport/MDSC/shadow.png"));
    painter.restore();
}

实现油耗表

​ 油耗表和之前舒适模式下内容一直，都是解析数字，替换资源，这里直接贴上代码，代码如下：

void MDS_CenteerMiniDisplay::drawRAFE(double rafe)
{
    int point,one,ten,temp;
    temp = rafe*10;
    point = temp%10;
    one = temp%100/10;
    ten = temp/100;

    switch (point) {
    default:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/0.png);}");
        break;
    }
    case 0:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/0.png);}");
        break;
    }
    case 1:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/1.png);}");
        break;
    }
    case 2:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/2.png);}");
        break;
    }
    case 3:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/3.png);}");
        break;
    }
    case 4:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/4.png);}");
        break;
    }
    case 5:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/5.png);}");
        break;
    }
    case 6:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/6.png);}");
        break;
    }
    case 7:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/7.png);}");
        break;
    }
    case 8:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/8.png);}");
        break;
    }
    case 9:
    {
        ui->label_1->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/9.png);}");
        break;
    }

    }

    switch (one) {
    default:
    {
        ui->label_2->setStyleSheet("QLabel{border-image:url(:/Sport/Resources/MeterDisplay/Sport/MDSC/number/0.png);}");
