Q:  I would like to convert a point returned in an NXEvent from its base coordinates to a view coordinate system.  There are several routines to convert coordinates between views and between the screen and base coordinate systems, but I have not found one to convert a base coordinate to a view's coordinate system.  How do I do this?

A:  Calling the following method with aView == nil converts the point from the base coordinate system of the window to the view's coordinate system:

- convertPoint:(NXPoint *)aPoint  fromView:aView;
