copied!<p>The Reason for disappearance of JScrollPane from the <code>ActualFrame</code> is that: You are adding the same instance of <code>pane</code> in <code>PreviewFrame</code>. So the actual container of the <code>pane</code> is now <code>PreviewFrame</code> instead of <code>ActualFrame</code>. When you maximize or resize the <code>ActualFrame</code>,it repaint its child components. Since the <code>pane</code> now no longer belongs to the <code>ActualFrame</code> it does not show the <code>pane</code> now.<P> The best way to avoid this situation is to create a seperate <code>JTabel</code> instance first, instead of passing anonymous <code>JTable</code> class object within the constructor of <code>JScrollPane</code> while creating the object <code>pane</code> . Get the <code>TableModel</code> and <code>TableColumnModel</code> of that <code>JTable</code> instance. In <code>previewFrame</code> add a new instance of <code>JScrollPane</code> that will contain the new instance of <code>JTable</code> with same <code>TableModel</code> and <code>TableColumnModel</code> objects. The Code would look something like this:</p> <pre><code>final JTable table = new JTable(data,columns); JScrollPane pane = new JScrollPane(table); ActualFrame.add(pane); ActualFrame.add(PrintPreviewBtn); PrintPreviewBtn.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { JFrame previewFrame = new JFrame("Preview"); javax.swing.table.TableModel tabModel = table.getModel(); javax.swing.table.TableColumnModel colModel = table.getColumnModel(); JScrollPane previewPane = new JScrollPane(new JTable(tabModel,colModel)); previewFrame.getContentPane().add(previewPane, BorderLayout.CENTER); previewFrame.pack();previewFrame.setVisible(true); } </code></pre>
