    <p>I've changed your code so that it doesn't require images, and now the turnLabel has been added. It is still too big, but it runs and shows some behaviors:</p> <pre><code>import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.util.ArrayList; import javax.swing.*; public class GameFrame extends JFrame { public static void main(String[] args) { JFrame gameFrame = new JFrame("MyGame"); gameFrame.setResizable(false); gameFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); gameFrame.add(new GamePanel()); gameFrame.pack(); gameFrame.setVisible(true); } } class GamePanel extends JPanel implements ActionListener { private BoardPanel boardPanel; // comprised of 9 mini panels /* RELEVANT */ private static TrackingPanel trackingPanel; // keeps track of score, turn, // and stuff private static Player playerX, playerO, turnPlayer; private ArrayList&lt;MiniGame&gt; miniGames; private Graphics graphics; private Graphics2D graphics2D; // constructor public GamePanel() { super(new BorderLayout()); setFocusable(true); // create 2 new players, and make it X's turn playerX = new Player(true, "X"); turnPlayer = playerX; playerO = new Player(true, "O"); // create tracking panel that will keep track of turns and stuff trackingPanel = new TrackingPanel(this); trackingPanel.setBorder(BorderFactory.createLineBorder(Color.red)); //!!

So now you must try to isolate your error as it may be in code left out. Perhaps it has something to do with concurrency as you mention in your question:</p> <blockquote> <p>2) What does this mean: "I wonder if your problem is a concurrency issue, that you are doing a long-running process on the Swing event thread and that this is preventing your label from updating its text." I read that somewhere else.</p> </blockquote> <p>So perhaps you have a long running process that you've not shown us in the code above.</p> <p>Also, your code has an over-use of static fields anti-pattern. Most of the fields that are static should <em>not</em> be static.</p>

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.
