I have added 8 x 8 = 64 JPanels on frame's content pane
with GridLayout and black/white alternate background color.
Yes, it's a chess board.

On each of those small JPanels, I can add a JLabel with
ImageIcon. Yes, they are chess pieces.

I saw in the JDK documentation how to D&D a text from a
JTextField onto a JLabel. But, how could I do D&D JLabel
over such multiple JPanels as the above chess board?

Could you give simple example code or pointers for them?

Thanks in advance.
