-/** - * - * Class <code>DropTarget</code> defines the target object for a drag and drop transfer. - * - * IMPORTANT: This class is <em>not</em> intended to be subclassed. - * - * <p>This class identifies the <code>Control</code> over which the user must position the cursor - * in order to drop the data being transferred. It also specifies what data types can be dropped on - * this control and what operations can be performed. You may have several DropTragets in an - * application but there can only be a one to one mapping between a <code>Control</code> and a <code>DropTarget</code>. - * The DropTarget can receive data from within the same application or from other applications - * (such as text dragged from a text editor like Word).</p> - * - * <code><pre> - * int operations = DND.DROP_MOVE | DND.DROP_COPY | DND.DROP_LINK; - * Transfer[] types = new Transfer[] {TextTransfer.getInstance()}; - * DropTarget target = new DropTarget(label, operations); - * target.setTransfer(types); - * </code></pre> - * - * <p>The application is notified of data being dragged over this control and of when a drop occurs by - * implementing the interface <code>DropTargetListener</code> which uses the class - * <code>DropTargetEvent</code>. The application can modify the type of drag being performed - * on this Control at any stage of the drag by modifying the <code>event.detail</code> field or the - * <code>event.currentDataType</code> field. When the data is dropped, it is the responsibility of - * the application to copy this data for its own purposes. - * - * <code><pre> - * target.addDropListener (new DropTargetListener() { - * public void dragEnter(DropTargetEvent event) {}; - * public void dragOver(DropTargetEvent event) {}; - * public void dragLeave(DropTargetEvent event) {}; - * public void dragOperationChanged(DropTargetEvent event) {}; - * public void dropAccept(DropTargetEvent event) {} - * public void drop(DropTargetEvent event) { - * // A drop has occurred, copy over the data - * if (event.data == null) { // no data to copy, indicate failure in event.detail - * event.detail = DND.DROP_NONE; - * return; - * } - * label.setText ((String) event.data); // data copied to label text - * } - * }); - * </pre></code> - * - * <dl> - * <dt><b>Styles</b> <dd>DND.DROP_NONE, DND.DROP_COPY, DND.DROP_MOVE, DND.DROP_LINK - * <dt><b>Events</b> <dd>DND.DragEnter, DND.DragLeave, DND.DragOver, DND.DragOperationChanged, - * DND.Drop, DND.DropAccept - * </dl> - */ -public final class DropTarget extends Widget {
