CButton封装的按钮按下事件处理

问题描述

我有一个我认为很容易解决的问题，但这是您可能知道或不知道的事情之一，而我却不知道！

我创建了一个从CButton继承的类，并在构造此新类的过程中传递了指向回调函数的指针，该函数需要在按下按钮时触发.

问题在于我无法在继承的CButton类本身中找到合适的事件使用，即使像BN_CLICKED这样的事件似乎也只能在继承于继承的CButton类的父窗口中工作.

任何帮助深表感谢.谢谢，戴夫.

Hi,

I have a problem that I imagine is fairly easy to solve but is one of those things you probably know or you don''t - and I don''t!

I have created a class inherited from a CButton, and as part of the construction of this new class I pass in a pointer to a callback function which I need to trigger when the button is pressed.

The trouble is that I can''t find an appropriate event to use within the inheritied CButton class itself as even such as BN_CLICKED only seem to work if trapped on the inherited CButton class'' parent window.

Any help massively appreciated. Thanks, Dave.

推荐答案

afx_msg BOOL OnClicked();

BEGIN_MESSAGE_MAP(YourButton, CButton)
    //{{AFX_MSG_MAP(CMtButton)
    ON_CONTROL_REFLECT_EX(BN_CLICKED, OnClicked)
    //}}AFX_MSG_MAP
END_MESSAGE_MAP()
