    <p>In fact, it's pretty easy. Don't use anonymous class.</p> <p>For example, with your code, you just have to attach a defined listener. For example :</p> <pre><code>bCircle.addActionListener(new SampleActionListener(pan, new CircleShapeGenerator())); </code></pre> <p>Here is the SampleActionListener witch implements the ActionListener interface</p> <pre><code>public class SampleActionListener implements ActionListener { private final DrawingCanvas canvas; private final ShapeGenerator shapeGenerator; public SampleActionListener(DrawingCanvas canvas, ShapeGenerator shapeGenerator) { this.canvas = canvas; this.shapeGenerator = shapeGenerator; } public void actionPerformed(ActionEvent event) { this.canvas.setShapeGenerator(shapeGenerator); } } </code></pre> <p>Here is the class CircleShapeGenerator</p> <pre><code>public class CircleShapeGenerator implements ShapeGenerator { public Shape getGeneratedShape(int x, int y) { return new Ellipse2D.Float(x, y, 10, 10); } } </code></pre> <p>and the interface ShapeGenerator</p> <pre><code>public interface ShapeGenerator { Shape getGeneratedShape(int x, int y); } </code></pre> <p>and, if you want to add the action listener on the rectangle button, it's really easy now. create this class:</p> <pre><code>public class RectangleShapeGenerator implements ShapeGenerator { public Shape getGeneratedShape(int x, int y) { return new Rectangle2D.Float(x, y, 10, 10); } } </code></pre> <p>and in your application class, add the following code</p> <pre><code>toolBar.add(bRectangle, toolBar.getComponentCount() - 1); bRectangle.addActionListerner(pan, new RectangleShapeGenerator() ) </code></pre> <p>for your method paint in your DrawingCanvas, i think, you should use a code like this :</p> <pre><code>for (Shape s : shapes) { Graphics2D g2 = (Graphics2D) g; g2.draw(s); } </code></pre> <p>BR, Patouche</p> <p>Sorry for my english, i know it's not really perfect...</p>

    1. COWow ! Sounds amazing, but I have quite a difficulty to all understand : `setShapeGenerator` is the setter for the arrayList ?

    2. COAnother thing, I really don't see what is the `public interface ShapeGenerator`, why do we need this ?

    3. COit's use in the ActionListener and in the class DrawingCanvas as a setter `setShapeGenerator`. So, in the class DrawingCanvas, on the method `mousePressed`, i will have something like `shapes.add(this.shapeGenerator.getGeneratedShape(e.getX(), e.getY())); repaint();`. I juste didn't write all the code. You can with this interface pass a CircleShapeGenerator or a RectangleShapeGenerator. I prefer to have this interface instead of having 4 or 5 ActionListener witch will add the Shape to the DrawingCanvas?

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.
