<P>
Finally, if you wish the VisRuler to take special action on certain mouse events (perhaps providing a mark on the ruler to track the mouse pointer's position), the GenView's content should intercept those mouse events and send messages to the VisRuler (again, the VisRuler at the top of the <CODE>
VRI_slave</CODE>
 chain) with the requested action.</P>
