This tip suggests a way to add drag images to JTree objects even when the underlying platform doesn't play ball. (1,100 words, August 2001)
Drag and drop (D&D) is an intuitive GUI gesture used for transferring data from one GUI component to another. This second article in the drag and drop series explores how you can transfer data besides text and discusses the issues involved with developing a library of D&D-enabled project Swing components.

Drag and drop (D&D) is an intuitive GUI gesture used for transferring data from one GUI component to another. This article explores the D&D classes introduced in the Java 2 platform (formerly JDK 1.2). To demonstrate the transfer of textual data locally (within a single Java virtual machine) and remotely (to other JVMs or native programs), seasoned Java instructor Gene De Lisa shows you how to subclass a Swing (JFC) component. This article includes a D&D Glossary. (4,000 words)
