My task is to connect in xpce prolog two squares, each of which equipped with a move_gesture, with a line/bezier curve in such a way that the line is moved along with the objects; does anyone know how this can be done or whether this is possible?

you could stretch the curve's control points when moving one of the objects while the other stays put. then re-draw the curve. – Will Ness Oct 16 '13 at 20:41

I think you need to implement by yourself, or consider that we have Qt available in SWI-Prolog now. – CapelliC Oct 16 '13 at 21:30
