I made A gui that is (640 200)x640 pixels big. On the left side is a chess board (it is at position 0,0 and has a size of 640x640.The 200 pixels on additional width are ment for some buttons to configure the game etc.

The problem:

The chess board's dimensions always have to be multiples of 8 to fit the frame perfectly. If i resize the frame a little bit so that its height increases by 7 pixels, there is a little gap between the chess board and the frame because the squares can't ne drawn in euqal size.

What is a clever way to fix this?

I assume you use Swing or AWT, using Frame or JFrame or Window or JWindow as the window you're working in.

Step 1) Put your chessboard into its own JPanel. Let's call that class ChessBoardPanel.

Step 2) Set the ChessBoardPanel's minimum, preferred and maximum sizes to the sizes you wish for in its constructor (or put it in a method if you wanna check the resize event of the parent and react to that, adjusting in 8px steps for bigger/smaller parent window.)

Step 3) Install a LayoutManager in the Window (window.setLayout(...)), like BoderLayout

Step 4) Create a new instance of the ChessBoardPanel: ChessBoardPanel myChessBoardPanel = new ChessBoardPanel(parentWindow);

Step 5) Add it to the parent window, maybe indicating layout behavior. For example, if you went with the BorderLayout, add it like this in the parent window: this.add(myChessBoardPanel, BorderLayout.WEST); so it will always be displayed on the left.
