    <p>You need to use a combination of <code>getPreferred/Minimum/MaximumSize</code> and a layout that will actually respect it.</p> <p>Here, I've used a <code>GridBagLayout</code> set up so that the board will always stay the same size, but the cell will use the maximum amount of same.</p> <p>If you want to keep the text at the bottom of the board (instead of the frame), remove the <code>weighty</code> constraint (and possibly the <code>weightx</code>) as well</p> <p><img src="https://i.stack.imgur.com/N2roi.png" alt="enter image description here"><img src="https://i.stack.imgur.com/4JmiM.png" alt="enter image description here"></p> <pre><code>public class TestBoardGame { public static void main(String[] args) { new TestBoardGame(); } public TestBoardGame() { EventQueue.invokeLater(new Runnable() { @Override public void run() { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException ex) { } catch (InstantiationException ex) { } catch (IllegalAccessException ex) { } catch (UnsupportedLookAndFeelException ex) { } JFrame frame = new JFrame("Test"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLayout(new GridBagLayout()); GridBagConstraints gbc = new GridBagConstraints(); gbc.gridx = 0; gbc.gridy = 0; gbc.weightx = 1; gbc.weighty = 1; frame.add(new BoardGamePane(), gbc); gbc.gridx = 0; gbc.gridy = 1; gbc.weightx = 1; gbc.fill= GridBagConstraints.HORIZONTAL; JLabel text = new JLabel("Area for text"); text.setHorizontalAlignment(JLabel.CENTER); frame.add(text, gbc); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } }); } public class BoardGamePane extends JPanel { public BoardGamePane() { setBorder(new LineBorder(Color.RED)); setBackground(Color.ORANGE); } @Override public Dimension getPreferredSize() { return new Dimension(400, 300); } @Override public Dimension getMinimumSize() { return getPreferredSize(); } @Override public Dimension getMaximumSize() { return getPreferredSize(); } } } </code></pre>

    1. COYour code is better then your text ... overriding `getPreferredSize` if you do custom painting is far better then calling `setPreferredSize`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
