| <P>Provides core support for the drop component of drag and drop. The two main types of |
| classes in this package are those that pertain to the drop target, and those |
| that pertain to adapting the transfer agent for the item to be dropped 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 Drop Target</h2> |
| <P>The {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drop.AbstractDropTargetListener |
| AbstractDropTargetListener}, which extends the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drop.IDropTargetListener |
| IDropTargetListener} for listening to drops, determines if the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drop.DropTargetContext |
| DropTargetContext} can support drops. Drop providers should subclass the |
| {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drop.AbstractDropTargetListener |
| AbstractDropTargetListener} and handle the SWT {@link |
| org.eclipse.swt.dnd.DropTargetEvent DropTargetEvent} or the GMF |
| {@link org.eclipse.gmf.runtime.common.ui.services.dnd.drop.DropTargetEvent |
| DropTargetEvent}.</P> |
| |
| <h2>The Drop Adapter</h2> |
| <P>The {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drop.TransferDropTargetAdapter |
| TransferDropTargetAdapter} implements the {@link |
| org.eclipse.gmf.runtime.common.ui.services.dnd.drop.ITransferDropTargetListener |
| ITransferDropTargetListener} 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.drop.IDropTargetListener |
| IDropTargetListener} array with {@link org.eclipse.swt.dnd.DropTargetEvent |
| DropTargetEvent} 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> |
