Find Mouse Location Inside CustomView

Hi folks,

Is there a NSView method that will tell me the current coordinates 
(NSPoint) of the mouse pointer relative to the NSView (in this case 
it is actually a CustomView) coordinate system.

I have found NSEvent('s) -mouseLocation but this gives at NSPoint 
relatively to the screen and NSWindow('s) -
mouseLocationOutsideOfEventStream and this gives an NSPoint relative 
to the Window. I guess it must be possible to transform from any or 
all of the different coordinate systems but just wanted to see if 
there is an easy Cocoa way to do find this information.

Regards,

Daniel
