JTabbedPane#getBoundsAt(int) may do the trick.

But I'd rather suggest you tried the following:

Assuming textArea1, textArea2, textArea3 are the components you want to
display.

private static class CustomPanel
extends JPanel
implements Scrollable
{
     public boolean getScrollableTracksViewPortWidth(){ return true; }

     //implement other Scrollable methods and JPanel c'tors accordingly
}

JPanel p = new CustomPanel();

JSplitPane spp = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, true,
texArea1, textArea2);
spp.setResizeWeight(.5);

spp = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, true, spp, textArea3);
spp.setResizeWeight(2d/3);

p.add(spp, BorderLayout.CENTER);

JScrollPane scp = new JScrollPane(p);

.. and make scp the tab component.

-.-

I might add that this idea of putting three textAreas in split panes
does NOT seem like a very wise choice, in terms of GUI design, to me.
Consequently, I'd suggest you got rid of them. The code would then look
like this:

JPanel p = new CustomPanel(new GridLayout(1, 3, 5, 5)); //implement
appropriate c'tor in CustomPanel

p.add(textArea1);
p.add(textArea2);
p.add(textArea3);

JScrollPane scp = new JScrollPane(p);

.. and make scp the tab component.

-.-

All code from scratch, uncompiled, untested -- no guarantees.
