    <p>In my application, I want to have a Swing panel with JavaFX control over it. For that, I use a JLayeredPane in which I insert a JPanel and a JFXPanel with a Scene that is not filled (aka <code>setFill(null)</code>). But no event passes through transparent areas of the JFXPanel to the Swing panel.</p> <p>Is there any solution to this problem ?</p> <p>Thanks</p> <p>Here an example :</p> <pre><code> public class TestJavaFX { private static JButton button; private static JFXPanel javafxPanel; public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { initAndShowGUI(); } }); } public static void initAndShowGUI() { JFrame frame = new JFrame("Swing application"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); javafxPanel = new JFXPanel(); button = new JButton("Swing - Push me"); JLayeredPane pane = new JLayeredPane(); pane.add(button, JLayeredPane.DEFAULT_LAYER); pane.add(javafxPanel, JLayeredPane.PALETTE_LAYER); pane.addComponentListener(new ComponentListener() { @Override public void componentShown(ComponentEvent e) { } @Override public void componentResized(ComponentEvent e) { button.setBounds(20, 50, 150, 30); javafxPanel.setBounds(0, 0, e.getComponent().getWidth(), e.getComponent().getHeight()); } @Override public void componentMoved(ComponentEvent e) { } @Override public void componentHidden(ComponentEvent e) { } }); frame.getContentPane().add(pane, BorderLayout.CENTER); Platform.runLater(new Runnable() { public void run() { createScene(); } }); // Show frame. frame.setSize(600, 400); frame.setVisible(true); } private static void createScene() { Button btn = new Button(); btn.setText("JavaFX - Push me"); VBox pane = new VBox(); pane.getChildren().add(btn); Scene scene = new Scene(pane); scene.setFill(null); javafxPanel.setScene(scene); } } </code></pre>

    1. COI think your problem is that you need to to set your Componenet listener to javafxPanel.addComponentListener instead of pane.addComponentListener. Try that and tell me what happens.

    2. COThanks, but my problem is not about resizing problem of the components but it is about not receiving events like mouse events. I found a solution by adding an event listener on the JavaFX scene and sending them to the underlying Swing component. But, I'd like to have a cleaner solution.

    3. COI'm afraid converting the events manually is actually the way to go here. I'm not aware of a more general event forwarding mechanism.

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.
