I’m trying to make a chessboard (8×8 grid) and fill it with background squares, but it always appears as a grid of empty squares. The image is called emptysquare.jpg but it does have a background color.
How to I correctly add an image to a JButton on the grid I have?
Answer
The reason that your chessboard is empty is due to the fact that you call JFrame#setVisible before adding your ChessSquare buttons to your panel. Ensure all component have been added before making this call.
Also set the Icon like this in ChessSquare
ImageIcon empty = ... setIcon(empty);
