Ricardo,

VFP doesn't really have a way of implementing interfaces like Java.

You can define abstract classes but there is no language enforcement that the methods remain empty.

define class GraphicObject as custom
   x = 0
   y = 0

function moveTo( newX, newY )
endfunc

function draw()
endfunc

enddefine
