    <p>I'm pretty new to Java (C# programmer) and I have here a problem that I dont understand. Sorry for the crappy english. =)</p> <p>I'm working on a simple Snake game, I have different classes, enums etc.. My problem is, if I call the JFrame with the game from the Menu class, it doesnt do anything. I can debug through the code but it doesnt draw anything. If I start the Game class direct from the Main method, there is no problem.</p> <p>I think that its a simple error and im just to stupid to see it.</p> <p>Here the code:</p> <p>Mouse Event:</p> <pre><code>else if (mouseX &gt; 75 &amp;&amp; mouseX &lt; 175 &amp;&amp; mouseY &gt; 260 &amp;&amp; mouseY &lt; 285) { startGame(); </code></pre> <p>startGame method in the Menu class:</p> <pre><code>public void startGame(){ this.setVisible(false); game = new Game(); } </code></pre> <p>Game Constructor:</p> <pre><code>public Game() { super("Snake V 0.1"); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(940, 620); setLocation(200, 200); addKeyListener(keyListener); setVisible(true); //this.createBufferStrategy(2); zeichnung.addFigur(new Field(0, 0)); snake = new Snake(40, 300, 1); zeichnung.addFigur(snake); zeichnung.addFigur(new Diamond()); this.getContentPane().add(jpanel); this.repaint(); this.Intervall(); } </code></pre> <p>Intervall:</p> <pre><code>public void Intervall() { while (true) { try { snake.direction = keyListener.getDirection(); zeichnung.checkCollision(snake); snake.move(); this.repaint(); Thread.sleep(150); } catch (InterruptedException e) { // TODO: handle exception } } } </code></pre> <p>As i said before. If I start the Game class direct from Main method (simple with Game game = new Game();) there is no problem.</p> <p>I hope I dont forgot any important information.</p>

    2. COIts not necessary. From main Method it works without "game.show()": public static void main(String[] args) { Menu menu = new Menu(); Game game = new Game(); } This works perfect

    3. COso the problem is that you want to call Game class from Menu Class , alright ?? and you call Menu class in Main class then call Game class in Menu class , did you?

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.
