You can override the UI method that calculates 2 the height for the tab button area, forcing 1 the height to 0 when there's only one tab:

tabbed_pane.setUI(new BasicTabbedPaneUI() {  
    @Override  
    protected int calculateTabAreaHeight(int tab_placement, int run_count, int max_tab_height) {  
        if (tabbed_pane.getTabCount() > 1)
            return super.calculateTabAreaHeight(tab_placement, run_count, max_tab_height);  
        else  
            return 0;  
    }  
});

I believe you'll have to do it manually. Apparently 5 it has been done before, but only as a small bit of a system which 4 seems to not be available.

Your approach 3 looks good to me. I would do it just like 2 you laid it out, and wrap all that logic 1 in a custom JComponent so it will feel less hackish.

You may be better off simply using CardLayout.

Another option would be to customize the 12 L&F delegate (either BasicTabbedPaneUI 11 or WindowsTabbedPaneUI depending on the 10 platforms you care about) used by the JTabbedPane. This 9 would allow you to customize the behavior 8 of the tabbed pane in the case where only 7 a single tab was being shown.

This is another 6 way of doing things however I would say 5 it's quite an undertaking and doing what 4 Michael said will get you where you want 3 to go with a lot less effort. I just wanted 2 to post this as an answer in case you weren't 1 aware of this option.

I think this can be achieved using tab bar 2 and a card layout,

add the tab bar and card layout to a grid bag layout so that they re-size automatically
the max height of the tab bar should be the height of the tab
add a listener to tab bar so that when certain tabs are clicked it will switch the card layout to show appropriate content
hide the tab bar if it has only one tab

and this should do the 1 job.

Yes, there is a way. Took me four hours 2 to find at the oracle website: http://docs.oracle.com/javase/7/docs/api/javax/swing/JTabbedPane.html#setTabLayoutPolicy()

Simply use 1 this:

//declare
private JTabbedPane editor = new JTabbedPane ();
//construct like this:
editor.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);
//just add components and see how it goes.
editor.addTab("", newPanel);

jTabbedPane1.removeTabAt(0); seems to work after initComponents();
