c++ - ON_LBN_SELCHANGE 的参数是什么？

Question

我在 MSDN 的任何地方都找不到处理 ON_LBN_SELCHANGE 的示例。那么，afx_msg函数长什么样子，消息映射中的ON_LBN_SELCHANGE需要哪些参数呢？

Answer 1

LBN_SELCHANGE 的通知处理程序没有参数。

所有列表框通知处理程序都有一个通用语法 ( link )

Each message-map entry takes the following form:

    ON_Notification( id, memberFxn )

where id specifies the child window ID of the list-box control sending the notification and memberFxn is the name of the parent member function you have written to handle the notification.

The parent's function prototype is as follows:

    afx_msg void memberFxn( );
