The framework calls this member function when the cursor hovers over the nonclient area of the window for the period of time specified in a prior call to TrackMouseEvent.

afx_msg void OnNcMouseHover(
    UINT nHitTest, 
    CPoint point



[in] nHitTest

The hit-test value returned by the CWnd::DefWindowProc function as a result of processing the WM_NCHITTEST message.

[in] point

A CPoint object that specifies the x and y coordinates of the cursor relative to the upper-left corner of the screen.

This method receives the WM_NCMOUSEHOVER notification, which is described in the Windows SDK.


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.

This method is supported in Windows Vista and later.

Additional requirements for this method are described in Build Requirements for Windows Vista Common Controls.
