This section discusses problems that you might encounter when using data transfer.
Problem: My drag gesture recognizer is not working properly with table/list/tree/text.
Do not use your own drag gesture recognizers with these components. Use setDragEnabled(true) and a TransferHandler.
Problem: I am unable to drop data onto my empty JTable.
You need to call setFillsViewportHeight(true) on the table. See
Empty Table Drop for more information.
