Method Detail

validateDrop

public boolean validateDrop(Object target,
                            int operation,
                            TransferData transferType)

Method for determining whether the drop target is a valid target. We could do extra validation on the source (drag) object(s), although that could get expensive. The SWT drag and drop framework calls this method.

performDrop

public boolean performDrop(Object data)

Called by SWT after the drop have been validated to perform the drop transfer.

getRunnableContext

protected IRunnableContext getRunnableContext(Shell shell)

dragOver

public void dragOver(DropTargetEvent event)
