title: SWT: Drag-and-drop Internal Object
body: <p>My application has a canvas and a table, I need to add drag-and-drop capabilities to it.  However, I read in a tutorial that Transfer converts the data I want to move into a platform-independent type.  I have no need to drag anything outside of my program, and it's important that the exact object be sent.  How can this be done?</p>
