如何在JDialog的标题栏中更改字体大小

Question

基本上是标题所说的。我无法更改JDialog中标题栏的字体大小。

 public MyDialog(Frame parent, Bank b) {
        super(parent, "Create Account", true);
        this.bank = b;

        Point loc = parent.getLocation();
        setLocation(loc.x + 420, loc.y + 260);
        JPanel panel = new JPanel();        

        setupGUI();
        fieldDataIsOK();
        getContentPane().add(panel);
        pack();
    }
