    <p>I'm writing java applet. I want to to open a new Frame with content actually stored in my Applet. I'm opening new Frame through the Button:</p> <pre><code>openInNew.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(ActionEvent e) { createDialog(); } }); //this Function retrieves Frame for applet public Frame getParentFrame( Component child ) { Container c = child.getParent(); while ( c != null ) { if ( c instanceof Frame ) { return ( Frame ) c; } c = c.getParent(); } return null; } private void createDialog() { Frame f=getParentFrame(openInNew); //openInNew is a button to Open a JDialog frame = new AppletFrame("NEW FRAME",jContentPane); frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); frame.setVisible(true); } </code></pre> <p>Here is the constructor for <code>AppletFrame</code>:</p> <pre><code>public AppletFrame(String string, JPanel jContentPane, Frame f) { super(f,string); this.setContentPane(jContentPane); this.setSize(790, 650); this.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) { removeAll(); FileListViewer.destroyFrame(); } }); } public static void destroyFrame() { jContentPane= (JPanel) frame.getContentPane(); jContentPane.repaint(); /*this one should repaint the Applet View, but the result * is still the same. jContentPane is not null, * it is filled with acutal components. */ jContentPane.setVisible(true); frame.dispose(); frame.setVisible(false); frame=null; } </code></pre> <p>My problem is that <code>jConentPane</code> is a reference, so immediately when I open my <code>AppletFrame</code> object, there is nothing stored in my basic Applet Frame. I wanted to set again <code>jContentPane</code> to <code>FileListViewer</code>, but I can't refer to non-static method in static <code>destroyFrame()</code>.</p>

    1. COWon't calling `JComponent component = (JComponent) frame.getContentPane();` inside your `destroyFrame()` method will solve your purpose ? So now you got the latest reference of the `Content Pane`, so you can do what you want with this I guess. I couldn't understand the question though, that's why this foolish question from my side :(

    2. COBTW - `FileListViewer` Is that list of files on the site, or the user machine?

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.
