Duilib的 WindowImplBase类有键盘响应函数，直接重写即可。至于键盘的虚拟码，可以去看下面这个：

上述代码中data是个单例模式的对象，如下定义：

class CData_2048
{
public:int _matrix[4][4];int current[4];int _count;int score;CTextUI* scores;vector<CButtonUI*>buttons;static CData_2048* GetInstance();static void Release();
private:CData_2048();static CData_2048*  t_;
};

关于移动类的方法没有做优化，有点挫了。
