Bold in JTabbedPane title overlapping tab edge

Question

I extended the BasicTabbedPaneUI and implemented paintText() to use a bold font if the tab is selected. This works OK, unless the tab has a long title in which case the bold text overlaps the edge of the tab. I tried using a smaller font size, but it still didn't work in some cases.
How do I change the size of the tab?
Here's my implementation:
-------------------------MyTabbedPane.java-----------------------
<pre>
import javax.swing.plaf.basic.BasicTabbedPaneUI;
import java.awt.*;
public class MyTabbedPaneUI extends BasicTabbedPaneUI {
     private Font boldFont = null;
     public MyTabbedPaneUI(Font font)
          this.boldFont = new Font(font.getFontName(), Font.BOLD, font.getSize());
     protected void paintText(Graphics g,
                              int tabPlacement,
                              Font font,
                              FontMetrics metrics,
                              int tabIndex,
                              String title,
                              Rectangle textRect,
                              boolean isSelected)
          if(isSelected)
               super.paintText(g, tabPlacement, boldFont, metrics, tabIndex, title, textRect, isSelected);
          else
               super.paintText(g, tabPlacement, font, metrics, tabIndex, title, textRect, isSelected);
</pre>
------Here's how it's used-----------
JTabbedPane tabbedPaneTop = new JTabbedPane(JTabbedPane.TOP, JTabbedPane.WRAP_TAB_LAYOUT);
// set-up tab UI
MyTabbedPaneUI tabUI = new MyTabbedPaneUI(tabbedPaneTop.getFont());
tabbedPaneTop.setUI(tabUI);

I figured out how to fix my problem. Had to override a couple more methods. See my code below.
import javax.swing.plaf.basic.BasicTabbedPaneUI;
import java.awt.*;
import javax.swing.*;
public class MyTabbedPaneUI extends BasicTabbedPaneUI {
     private Font boldFont = null;
     private FontMetrics boldFM = null;
     public MyTabbedPaneUI(Font font)
          this.boldFont = new Font(font.getFontName(), Font.BOLD, font.getSize());
     public void installUI(JComponent c)
          super.installUI(c);
          this.boldFM = c.getFontMetrics(this.boldFont);
     protected void paintText(Graphics g,
                   int tabPlacement,
                   Font font,
                   FontMetrics metrics,
                   int tabIndex,
                   String title,
                              Rectangle textRect,
                   boolean isSelected)
          if(isSelected)
               Rectangle rect = this.getTabBounds(this.tabPane, tabIndex);
               int centerX = rect.x + rect.width/2;
               int centerY = rect.y + rect.height/2;
               int textH = this.boldFM.getHeight();
               int textW = this.boldFM.stringWidth(this.tabPane.getTitleAt(tabIndex));
               rect.x = centerX - textW/2;
               rect.y = centerY - textH/2;
               rect.width = textW;
               rect.height = textH;
               super.paintText(g, tabPlacement, boldFont, this.boldFM, tabIndex, title, rect, isSelected);
          else
               super.paintText(g, tabPlacement, font, metrics, tabIndex, title, textRect, isSelected);
     protected int calculateTabWidth(int tabPlacement, int tabIndex, FontMetrics metrics)
          if (this.tabPane.getSelectedIndex() == tabIndex)
               return super.calculateTabWidth(tabPlacement, tabIndex, this.boldFM);
          else
               return super.calculateTabWidth(tabPlacement, tabIndex, metrics);
}
