CWnd::OnActivate

The framework calls this member function when a CWnd object is being activated or deactivated.

afx_msg void OnActivate(
   UINT nState,
   CWnd* pWndOther,
   BOOL bMinimized 
);

Parameters

  • nState
    Specifies whether the CWnd is being activated or deactivated. It can be one of the following values:

    • WA_INACTIVE   The window is being deactivated.

    • WA_ACTIVE   The window is being activated through some method other than a mouse click (for example, by use of the keyboard interface to select the window).

    • WA_CLICKACTIVE   The window is being activated by a mouse click.

  • pWndOther
    Pointer to the CWnd being activated or deactivated. The pointer can be NULL, and it may be temporary.

  • bMinimized
    Specifies the minimized state of the CWnd being activated or deactivated. A value of TRUE indicates the window is minimized.

    If TRUE, the CWnd is being activated; otherwise deactivated.

Remarks

If the CWnd object is activated with a mouse click, it will also receive an OnMouseActivate member function call.

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.
