dragEntered

protected void dragEntered(javax.swing.JComponent destination,
                           java.awt.datatransfer.Transferable transferable,
                           int dragAction)

Called once transferable data entered in destination component during a drag and drop operation. Subclasses should override this method if they are interested by this event.

Parameters:

dragAction - the current drag action (TransferHandler.COPY, TransferHandler.MOVE or TransferHandler.LINK)

dragMoved

protected void dragMoved(javax.swing.JComponent destination,
                         java.awt.datatransfer.Transferable transferable,
                         int dragAction)

Called when transferable data moved in destination component during a drag and drop operation. Subclasses should override this method if they are interested by this event.

Parameters:

dragAction - the current drag action (TransferHandler.COPY, TransferHandler.MOVE or TransferHandler.LINK)

dragExited

protected void dragExited(javax.swing.JComponent destination)

Called once the cursor left destination component during a drag and drop operation. Subclasses should override this method if they are interested by this event.

canImportFlavor

protected abstract boolean canImportFlavor(java.awt.datatransfer.DataFlavor[] flavors)

Returns true if flavors contains a flavor that can be imported by this transfer handler. Subclasses should override this method to return which flavors it supports.
