Now we come to a small detail. Our drawing widget needs to have a pointer to the xy-plot widget such that it can post data there. Moreover, the drawing widget requires a pointer to the ball logic, such that it can inquire about the position of the ball at the current time. All three widgets need to talk to each other, therefore a pointer is required which allows for communication, xyPlot.
