    <p>I am a Java student and just ended the basic functionality of a little command line card game. The game is a simplified version of Magic-type trading card game. There is no AI, you play against yourself or another human player. </p> <p>At this point, i am trying to add some GUI to it using MVC, but <strong>i'm finding problems adding a MouseListener to a button</strong>.</p> <p>This is a brief explanation of what's going on:</p> <ul> <li>I have a <code>Model</code> class, that extends <code>Observable</code> by inheritance of a superclass</li> <li>A <code>View</code> class, that implements <code>Observer</code>.</li> <li>And a <code>Controller</code> class that extends <code>MouseAdapter</code></li> </ul> <p>Then i put everything together:</p> <pre><code>.... View view = new View(); Model model = new Model(); model.addObserver( view ); Controller controller = new Controller(); // associate Controller's Model and View objects controller.addModel(model); controller.addView(view); view.addController(controller); // i try to add the MouseListener .... </code></pre> <p>The addController() method of View is:</p> <pre><code>public void addController(Controller controller){ this.myButton.addMouseListener( controller ) } </code></pre> <p>I already checked that <code>addController()</code> method is being called (println something inside it), but the Listener is not being set for some reason: <code>mouseReleased()</code> is never called when i click the button.</p> <p>Any thoughts or any step that i may have overlooked? Appreciate.</p> <p><strong>Edit (Controller code):</strong></p> <pre><code>public class Controller extends MouseAdapter { Model model; View view; public void addModel(Model m){ this.model = m; } public void addView(View ui){ this.view = ui; } // All @Overrides @Override public void mouseReleased(MouseEvent me) { System.out.println("oh, it arrived"); } } </code></pre>

    1. CO1. [maybe will help you with one of possible logics](http://stackoverflow.com/questions/8169964/is-mvc-in-swing-thread-safe), 2. notice output to the Swing GUI should be wrapped in invokeLater, 3. again for better help sooner post an [SSCCE](http://sscce.org/), short, runnable, compilable, 4. because we can't see rest of (importannt) code, 5. those code lines talking about ...

    2. COCan you show the code from Controller? Maybe you are not correctly overriding the method from MouseAdapter. This is the signature of the method "public void mouseReleased(MouseEvent e)"

    3. COThe mouse events may be begin consumed by the button and never reaching you for further processing. Better to use an action listener on a button, which will also be fired if the user presses space or enter when the button is focused

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.
