JTabbedPane not displaying JPanel properly

Question

I am trying to add a JPanel to a tab. However it does not display the button components or toolbars ive added to the panel. I am new to this so might be doing it completely wrong. Any advice would be appreciated.

Something like this:

public class JTabbedPaneFrame extends JFrame  
{

   public JTabbedPaneFrame()
   {


      JTabbedPane tabbedPane = new JTabbedPane(); 
      SortPanel p = new SortPanel();
      panel p1 = new Panel();



      tabbedPane.addTab( "Tab One", null, p1, "First Panel" ); 
      add( tabbedPane );
}

Answer 1

Try adding the tabbed pane to another JPanel, then add that JPanel to the JFrame:

tabbedPane.addTab( "Tab One", null, p1, "First Panel" );    
JPanel anotherPanel = new JPanel();
anotherPanel.add(tabbedPane);
add(anotherPanel);
