Problem with tabbed panes

[pandu chinnu]

Hi,

I was trying to create tabbed pane each pane name 'AuthorOne' , 'Authortwo' and 'Authorthree' ; however all having the same fuctionality. That is, on clicking any one of the three tabs, you get to see the same panel. The panel that I have added to all three tabs is Panel1, however on running the code I see only author 3 tab...what happened to authorone and author2 tab. Please note that panel1 contains another 2 panels with buttons and textarea.

 
 tabbedpane = new JTabbedPane();
 
Component p1 = panel1;
 tabbedpane.addTab("Author One",p1);
        
   Component p2 = panel1;   
   tabbedpane.addTab("Author Two",p2);
        
   Component p3 = panel1;       
   tabbedpane.addTab("Author Three",p3);
       
    //Add the tabbed pane to frame
     frame.getContentPane().add(tabbedpane);

Hi Pandu,

You may want the same panel object on each of the tabs, but you will need a separate instance of the panel for each. You are basically adding the same component to the tabbed pane three times, and renaming it each time. Thus, the last name is the one displayed.
Create three of whatever panel1 is, and add those three objects to the tabbed pane.

Hope that helps,

Darrin

Hi,

I thought of that, however panel1 contains panel2 and panel3 which again contains a number of components. So do I again rewrite the entire code?

Even if I do some thing like:

 tabbedpane = new JTabbedPane();
 

 Component p1 = panel1;
        tabbedpane.addTab("Author One",p1);
        
        panel4 = new JPanel();
 panel4.add(panel1);
   Component p2 = panel4;   
        tabbedpane.addTab("Author Two",p2);
        
        panel5 = new JPanel();
 panel5.add(panel1);
   Component p3 = panel5;       
        tabbedpane.addTab("Author Three",p3);
       
      //Add the tabbed pane to this frame
       frame.getContentPane().add(tabbedpane);   

it dosen't seem to work,,,only the Author Three tab displays.

If you don't want the tabs to actually control what appears underneath, you could try something like this:

JTabbedPane tabs = new JTabbedPane();
tabs.addTab("One", null);
tabs.addTab("Two", null);
tabs.addTab("Three", null);
 
// set preferred size so only the tabs fit
Dimension d = tabs.getPreferredSize();
d.height = 2 + tabs.getUI().getTabBounds(tabs, 0).height;
tabs.setPreferredSize(d);

// place the complicated panel (or whatever) underneath
JPanel p = new JPanel(new BorderLayout());
p.add(tabs, BorderLayout.NORTH);
p.add(createComplicatedPanel(), BorderLayout.CENTER);
