在前面GC9项目之前其实单独写过一个HUD，这里就直接把原来的资源弄过，按照现在的想的思路重新搞一次。

HUD北京为透明，这样可以感觉是真的投在玻璃上。HUD上面目前引出的接口如下

/**
     * @brief fastStart
     * 快速启动
     */
    void fastStart();
    /**
     * @brief selfInspection
     * 自检程序
     */
    void selfInspection();
    /**
     * @brief powerUp
     * HUD上电操作
     */
    void powerUp();
    /**
     * @brief powerOff
     * HUD断电操作
     */
    void powerOff();
    /**
     * @brief setLaneKeeping
     * 设置车道保持
     */
    void setLaneKeeping(LaneKeep temp = m_LaneKeep_No);
    /**
     * @brief setCruiseControl
     * @param temp
     * 设置定速巡航
     */
    void setCruiseControl(bool temp);
    /**
     * @brief setSelfAdaptiveCruiseControl
     * @param temp
     * 设置自适应巡航
     */
    void setSelfAdaptiveCruiseControl(bool temp);
    /**
     * @brief setSelfAdaptiveCruiseControlDistance
     * @param temp
     * 设置距离
     */
    void setSelfAdaptiveCruiseControlDistance(int temp);
    /**
     * @brief setSelfAdaptiveCruiseControlModel
     * @param temp
     * 设置自适应巡航模式
     */
    void setSelfAdaptiveCruiseControlModel(SelfAdaptiveCruiseControlModel temp);
    /**
     * @brief setCarSpeed
     * @param temp
     * 设置车速
     */
    void setCarSpeed(int temp);
    /**
     * @brief setTurnLight
     * @param temp
     * 设置转向灯
     */
    void setTurnLight(int temp);
    /**
     * @brief setDirection
     * @param temp
     * 设置导航方向
     */
    void setDirection(Direction temp);
    /**
     * @brief setDirectionDistance
     * @param temp
     * 设置距离
     */
    void setDirectionDistance(int temp = 150);

HMI-58-【多媒体】重构底部菜单
今天的这个没有新的内容，就是计划重新构建下底部菜单，开始是在每个界面里面都做了底部菜单，开始我以为每个界面都不一样，和面我研究了一下发现，每个界面的底部菜单都是一样的呀，那我们就好所了，开始重构。把底部菜单移到他的父页面中。
