/** * PRAXIS-INFO * * We will now address a persistent problem in our animations - how to refresh * the display of an object without getting the warning that we should not be * asking ObjectEditor explicitly to refresh the object. * * This is part of a bigger problem, how to create multiple views of an object * that are kept consistent. * * * This, in turn, is part of an even bigger problem: how to decompose the * functionality of an interactive application into different objects. * * The solution to the last problem is a a recurring "pattern" called MVC - for * Model-View-Controller. * * A component of MVC is a pattern called Observer, which provides a solution * to the first and second problems. * * In lecture slides, we start with the last problem and gradually reduce it. * * Here we will start with the second problem and gradually increase it. * * NAVIGATION-INFO * * ANonObservableLine * AnObservableLine * APropertyListenerSupport * */ package lectures.mvc.properties; import util.annotations.WebDocuments;
