TTM_WINDOWFROMPOINT


TTM_WINDOWFROMPOINT 
    wParam = 0; 
    lParam = (POINT FAR *) lppt; 

Allows a subclass procedure to cause a tooltip to display text for a window other than the one beneath the mouse cursor.

lppt
Address of a POINT structure that defines the point to be checked.

This message is intended to be processed by an application that subclasses a tooltip. It is not intended to be sent by an application. A tooltip sends this message to itself before displaying the text for a window. By changing the coordinates of the point specified by lppt, the subclass procedure can cause the tooltip to display text for a window other than the one beneath the mouse cursor.
