CWnd::OnRegisteredMouseWheel

Visual Studio 2010

The framework calls this member function as a user rotates the mouse wheel and encounters the wheel's next notch.

Copy 
afx_msg LRESULT OnRegisteredMouseWheel(
   WPARAM wParam,
   LPARAM lParam 
);
wParam

Horizontal position of the pointer.

lParam

Vertical position of the pointer.

Insignificant at this time. Always zero.

Unless overridden, OnRegisteredMouseWheel routes the message to the appropriate window (the parent window with focus), and calls the WM_MOUSEWHEEL handler for that window.

Override this member function to provide your own message routing or to alter the mouse-wheel scrolling behavior.

Note Note

OnRegisteredMouseWheel handles messages for Windows 95/98 and Windows NT 3.51. For Windows NT 4.0 message handling, use OnMouseWheel.
