Drag and Drop: New Data Transfer Capabilities in the JavaTM 2 Platform, Standard Edition (J2SETM), version 1.4(15) The following sample program combines all of these operations. There is one draggable text label, one draggable image label, one droppable image label, and a text field for dropping the text.
