Class DataTransferHandler

java.lang.Object
  jApp.DataTransferHandler

public abstract class DataTransferHandler
extends java.lang.Object

The DataTransferHandler implements most of the functionality needed for Drag / Drop and Copy / Paste functionality. Typically Applications instantiate in Document.createDataTransferHandler() one instance of a class derived from DataTransferHandler which implements createTransferable(JComponent, MouseEvent),canImport(JComponent, DataFlavor[]) and importData(Transferable, JComponent, Point). To enable this is enough to support Copy/Paste functionality. To support Drag and Drop the DataTransferHandler needs to be associated with one or more JComponents by calling addDataSource(JComponent).
