| <P>Provides core support for the drag component of drag and drop. The two main types of |
| classes in this package are those that pertain to the drag source, and those |
| that pertain to adapting the transfer agent for the item to be dragged for use |
| with the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.core.TransferAdapterProvider |
| TransferAdapterProvider}. See the schema documentation for |
| transferAdapterProviders for more information.</P> |
| |
| <h2>The Drag Source</h2> |
| <P>The {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drag.AbstractDragSourceListener |
| AbstractDragSourceListener}, which extends the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drag.IDragSourceListener |
| IDragSourceListener} for listening to drags, determines if the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drag.DragSourceContext |
| DragSourceContext} is draggable. Drag providers should subclass the |
| {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drag.AbstractDragSourceListener |
| AbstractDragSourceListener} and handle the {@link |
| org.eclipse.swt.dnd.DragSourceEvent DragSourceEvent}.</P> |
| |
| <h2>The Drag Adapter</h2> |
| <P>The {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drag.TransferDragSourceAdapter |
| TransferDragSourceAdapter} implements the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drag.ITransferDragSourceListener |
| ITransferDragSourceListener} interface. It adapts the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.core.ITransferAgent |
| ITransferAgent} for use with the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.core.TransferAdapterProvider |
| TransferAdapterProvider} and notifies its {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drag.IDragSourceListener |
| IDragSourceListener} array with {@link org.eclipse.swt.dnd.DragSourceEvent |
| DragSourceEvent} notifications.</P> |
| |
| <h2>Package Specification</h2> |
| |
| <P>For more information on transferring data using Eclipse drag and drop, please |
| see {@link org.eclipse.swt.dnd.Transfer org.eclipse.swt.dnd.Transfer} and {@link |
| org.eclipse.swt.dnd.TransferData org.eclipse.swt.dnd.TransferData}.</P> |
