    <p>I am using java to make a simple game. I have code that forty times a second, runs the screen thread. However, whenever i call the screen thread a new window opens up and the old one also stays open. Is there a way I can fix this? Thanks</p> <pre><code>package sylvyrfysh; import java.awt.*; import javax.swing.*; import sylvyrfysh.handlers.OreHandler; import sylvyrfysh.troops.manager.TroopManager; public class Screen extends JFrame implements Runnable{ private static final long serialVersionUID = -377919050238217712L; public Screen(){ super("Commander"); setContentPane(new DrawPane()); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setFont(new Font("Arial",Font.PLAIN,12)); setSize(607,669); setVisible(true); setResizable(false); KeyboardFocusManager manager=KeyboardFocusManager.getCurrentKeyboardFocusManager(); manager.addKeyEventDispatcher(new EventHandler()); addMouseListener(new MouseHandler()); } class DrawPane extends JPanel{ private static final long serialVersionUID = 2729138328693556841L; public void paintComponent(Graphics g){ g.setColor(Color.BLACK); g.fillRect(0,0,600,40); g.setColor(Color.CYAN); g.drawString("Ore: "+Main.ore,0,10); g.drawString("Base Health: "+Main.baseHealth,0,30); g.setColor(Color.BLUE); g.fillRect(0,40,600,600); g.setColor(Color.GREEN); g.fillRect(0,40,100,100); for(int[] i:TroopManager.troops){ g.fillRect(i[1],i[2]+40,1,1); } g.setColor(Color.RED); g.fillRect(500, 540, 100, 100); for(int[] i:TroopManager.enemyTroops){ g.fillRect(i[1],i[2]+40,1,1); } g.setColor(Color.YELLOW); for(int[] i:OreHandler.ore){ g.fillRect(i[1],i[2]+40,1,1); } } } public void run(){repaint();} } </code></pre> <p>EDIT: What appears to be happening is whenever i call the screen thread, it also calls the constructor.</p>

    1. COFor better help sooner, post an [SSCCE](http://sscce.org/). Once that code is changed to be compilable and runnable, I see only one frame.

    2. COWhat does "call the screen thread" mean? It would be helpful if you posted the code that does this.

    3. CO@StuartMarks And then we can look forward to dribs-and-drabs of code snippets the OP thinks might be relevant. Tip: someone that can't solve the problem is hardly likely to know which part of the codes are relevant. An SSCCE ***guarantees*** the relevant code is present.

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.
