JTabbedPane - Adding Tab to the right

Question

In my program, I am using a JTabbedPane, which shows several settings pages. Now i want to add a "help" screen to it, in a new tab, but I would like to align that tab to the right, the same effect like adding a Box.createHorizontalGlue() to a JMenuBar.
My question graphically: http://home.arcor.de/sidiousx/tab.gif
I searched the API and I tried subclassing JTabbedPane and changing the UI (but I'd rather not subclass the UI, because I use different Look and Feels), but it wass all useless. Anyone got an idea?

Answer 1

Hm and how would you do this?
I tried to sub-class BasicTabbedPaneUI:
class TabUI extends BasicTabbedPaneUI
    public Rectangle getTabBounds(int index, Rectangle rect)
        if (index == rects.length - 1) {
            rect = super.getTabBounds(index, rect);
            rect.x += 100;
            return rect;
        } else {
            return super.getTabBounds(index, rect);
}But:
1. It doesn't look good in Metal-LookAndFeel
2. It doesn't work ;) If the last Tab is selected, you can see some kind of shadow, where the tab should be (in this test), but nothing more.
