CWnd::OnRegisteredMouseWheel
The framework calls this member function as a user rotates the mouse wheel and encounters the wheel's next notch.
afx_msg LRESULT OnRegisteredMouseWheel(
WPARAM wParam,
LPARAM lParam
);
Parameters
wParam
Horizontal position of the pointer.lParam
Vertical position of the pointer.
Return Value
Insignificant at this time. Always zero.
Remarks
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
OnRegisteredMouseWheel handles messages for Windows 95/98 and Windows NT 3.51. For Windows NT 4.0 message handling, use OnMouseWheel.
