    copied!<p>I want to know can we have a JPanel with a Layout other than its Parent JFrame. For example. If I have JFrame with Border Layout and we have a JPanel embedded on it and it is having different Layout. Is it possible ?</p> <p>I am trying to do it. But this way the components of that JPanel are not showing.</p> <p>Here comes the problem in detail : </p> <p>I have a JFrame and layout for it is Border Layout. I am adding a JPanel on this frame. If I donot set any Layout for the JPanel. All components of JPanel are displaying on the window but When I am setting Grid Layout for JPanel, Components of JPanel are not visible. I am adding Layout to JPanel so as to align the Components. Below is my code :</p> <p>I have a main class, a frame class and Jpanel class.</p> <pre><code> public class AppMain { public static void main(String[] args) { AppPage1 page1 = new AppPage1("test"); page1.setVisible(true); } } public class AppPage1 extends JFrame { public AppPage1(String title) throws HeadlessException { super(title); this.setLayout(new BorderLayout()); addWindowListener(new WindowAdapter() { public void windowOpened(WindowEvent e) { setExtendedState(MAXIMIZED_BOTH); } }); //Panel for logo JLabel testLogo = new JLabel(""); testLogo.setIcon(new javax.swing.ImageIcon("test.JPG")); List&lt;JComponent&gt; componentList = new ArrayList&lt;JComponent&gt;(); componentList.add(testLogo); PagePanel logoPanel = new PagePanel(componentList,null); this.add(logoPanel, BorderLayout.NORTH); //Panel for Button and checkboxes JLabel panelTitle = new JLabel("test Wizard"); JRadioButton rdButton_ExistingConfigurationFile = new JRadioButton("Existing Configuration File"); JRadioButton rdButton_ConfigureNewPropertyFile = new JRadioButton("Configure new Property File"); componentList = new ArrayList&lt;JComponent&gt;(); componentList.add(panelTitle); componentList.add(rdButton_ExistingConfigurationFile); componentList.add(rdButton_ConfigureNewPropertyFile); PagePanel buttonPanel = new PagePanel(componentList,new GroupLayout(this)); this.add(buttonPanel, BorderLayout.CENTER); this.pack(); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); validate(); } } public class PagePanel extends JPanel { public PagePanel(List&lt;JComponent&gt; componentList, LayoutManager layOutManager) { this.setBackground(Color.decode("#4E6987")); if (layOutManager != null) { this.setLayout(null); } for (JComponent jComponent : componentList) { jComponent.setBackground(Color.decode("#4E6987")); this.add(jComponent); } } } </code></pre> <p>Thanks in Advance Ravi Kumar</p>
