Java Swing - How to change the font size on a JPanel's TitledBorder?

Question

I need to be able to programmatically change the font size of all the components in my Swing app. I cannot do this in the usual ways (with UIManager or putClientProperty) as

Answer 1

The following worked for me:

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    ((javax.swing.border.TitledBorder) jPanel1.getBorder()).
        setTitleFont(new Font("Arial", Font.ITALIC, 14));

    jPanel1.repaint();
}

I've tested this in NetBeans 6.9.1
