简介： Qt [GC9-23]：模拟汽车上电液晶仪表部分

液晶仪表部分的模拟上电其实和HUD部分的模拟上电逻辑是一样的，这里先看下效果。

看下舒适模式下的初始化

/**
 * @brief MD_Comfort::init_MD_Comfort
 * @param initType
 * 舒适画面初始化
 */
void MD_Comfort::init_MD_Comfort(int initType)
{
    switch (initType) {
    case 0:
    {
        m_turnLeftAndRightLight->hide();
        m_rotateSpeed->hide();
        m_carSpeed->hide();
        m_title->hide();
        m_Map->hide();
        m_startLogo->hide();
        m_tpms->hide();
        break;
    }
    case 1:
    {
        m_turnLeftAndRightLight->show();
        m_turnLeftAndRightLight->powerUp();
        m_rotateSpeed->show();
        m_rotateSpeed->powerUp();
        m_carSpeed->show();
        m_carSpeed->powerUp();
        m_title->show();
        m_Map->hide();
        m_startLogo->show();
        m_startLogo->powerUp();
        m_tpms->show();
        m_tpms->powerUp();
        break;
    }
    case 2:
        break;
    case 3:
        break;
    default:
        break;
    }
}

这部分代码开始没有多少，是因为在液晶仪表这里，我把到多东西都写进里子控件里面，每个控件有一个上电函数“powerup”

每一个powerup的实现原理就是开始都是隐藏的，根据需要显示出来

    ui->label_turnLight_L->show();

        ui->label_turnLight_R->hide();
    });
}

    }
    else
