Package org.eclipse.gmf.runtime.common.ui.services.dnd.drag Description

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 TransferAdapterProvider. See the schema documentation for transferAdapterProviders for more information.

The Drag Source

The AbstractDragSourceListener, which extends the IDragSourceListener for listening to drags, determines if the DragSourceContext is draggable. Drag providers should subclass the AbstractDragSourceListener and handle the DragSourceEvent.

The Drag Adapter

The TransferDragSourceAdapter implements the ITransferDragSourceListener interface. It adapts the ITransferAgent for use with the TransferAdapterProvider and notifies its IDragSourceListener array with DragSourceEvent notifications.

Package Specification
