CWnd::OnSetFocus
The framework calls this member function after gaining the input focus.
afx_msg void OnSetFocus(
CWnd* pOldWnd
);
Parameters
- pOldWnd
Contains the CWnd object that loses the input focus (may be NULL). The pointer may be temporary and should not be stored for later use.
Remarks
To display a caret, CWnd should call the appropriate caret functions at this point.
注意
This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
