Until now, drag and drop for web applications has, for the most part, been limited to specialized JavaScript frameworks such as Script.aculo.us and Rico. No more. With the advent of GWT, we have drag-and-drop capabilities in a Java-based web application framework. Although Google Web Toolkit (GWT) does not explicitly support drag and drop (drag and drop is an anticipated feature in the future), it provides us with all the necessary ingredients to make our own drag-and-drop module. In this solution, we explore drag-and-drop implementation with GWT. We implement drag and drop in a module of its own so that you can easily incorporate drag and drop into your applications.
