Question

WTL怎么让View来响应菜单事件

Answer 1

先要改View里面的消息循环，把它写成如下形式：
程序代码
BEGIN_MSG_MAP(CGameView)
MESSAGE_HANDLER(WM_PAINT, OnPaint)
MESSAGE_HANDLER(WM_Create, OnCreate)
ALT_MSG_MAP(1) // Handle notify message.
COMMAND_ID_HANDLER(ID_GAME_START_NEW, OnGameStartNew)
END_MSG_MAP()

然后在CMainFrame的消息循环中加入CHAIN_MSG_MAP_ALT_MEMBER()：
程序代码
BEGIN_MSG_MAP(CMainFrame)
MESSAGE_HANDLER(WM_Create, OnCreate)
CHAIN_MSG_MAP(CUpdateUI<CMainFrame>)
CHAIN_MSG_MAP(CFrameWindowImpl<CMainFrame>)
CHAIN_MSG_MAP_ALT_MEMBER(m_view, 1)
END_MSG_MAP()
