TextLayout swallows Tab Spacings.

Question

Hi,
I'm having trouble rendering tab spacings using Java2D.
The tab spacings seems to be swallowed/ignored.
Here's a simple test application. Am I doing something wrong or missing something? Or is this a bug?
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.font.TextLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class TextLayoutTabSpacingTest extends JPanel
  @Override
  public void paint(Graphics g)
    float X = 40;
    float Y = 80;
    Graphics2D g2 = (Graphics2D) g;
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    Font oFont = new Font("Serif", Font.PLAIN, 32);
    TextLayout oTextLayout = null;
    String sOriginalText = "Tab spacings where art thou?\n1\t2\t3\t4\t5\n6\t7\t8\t9\t10\n11\t12\t13\t14\t15";
    String[] aText = sOriginalText.split("\n");
    for(String sText : aText)
      System.out.println("\nText       -> " + sText);
      oTextLayout = new TextLayout(sText, oFont, g2.getFontRenderContext());
      System.out.println("TextLayout -> " + oTextLayout);
      oTextLayout.draw(g2, X, Y);
      Y += 40;
  public static void main(String[] args)
    JFrame f = new JFrame("TextLayout Tab Spacing Test.");
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.getContentPane().add(new TextLayoutTabSpacingTest());
    f.setSize(500, 300);
    f.setVisible(true);
}Thank you.

Looks like you didn't understand Stas' advice.
... and then paint the pane.You already have a JEditorPane with all formatting, so half of that advice has become redundant. Just invoke the JEditorPane's paintComponent(...) with the graphics reference you are using for what you call 'the whole screen' possibly after translating or otherwise applying a suitable transform.

edit Saw #5 and 6 after posting that.
@Stas: Did I interpret your previous response correctly?
