覆盖JButton paintComponent()不起作用

Question

我想绘制自己的JButton版本,所以我重写了paintComponent()方法,并画了一个渐变roundRect.这可行,但在那之后,我想在它上面绘制Button的字符串,并在编译时,我没有错误消息.但是在运行时,我只看到了roundRect,渐变,就像我想要的那样(我也可以点击它),但是String是不可见的......

这是我的代码:

import javax.swing.*;
import javax.swing.border.*;
import java.awt.*;
import java.awt.event.*;

public class JIconButton extends JButton implements MouseListener
{
    private boolean mouseInside;
    public JIconButton(String file, String text)
    {
        super(text, new ImageIcon(file));
        setBorder(new LineBorder(Color.LIGHT_GRAY, 0, true));
        setContentAreaFilled(false);
        setFocusPainted(false);
        addMouseListener(this);
        setVisible(true);
    }

    public void mouseClicked(MouseEvent e)
    {

    }

    public void mouseEntered(MouseEvent e)
    {

    }

    public void mouseExited(MouseEvent e)
    {

    }

    public void mousePressed(MouseEvent e)
    {

    }

    public void mouseReleased(MouseEvent e) 
    {

    }

    @Override
    protected void paintComponent(Graphics g)
    {
        Graphics2D g2 = (Graphics2D)g.create();
        g2.setPaint(Color.BLACK);
        g2.drawString(getText(), 0, 0);
        g2.setPaint(new GradientPaint(
                new Point(0, 0), 
                Color.WHITE, 
                new Point(0, getHeight()), 
                Color.PINK.darker()));
        g2.fillRoundRect(0, 0, getWidth(), getHeight(), 30, 30);
        g2.dispose();

        //super.paintComponent(g);
    }
}

根据我的评论,"它对我有用......"
例如:

   @Override
   protected void paintComponent(Graphics g) {
      Graphics2D g2 = (Graphics2D) g.create();
      g2.setPaint(new GradientPaint(new Point(0, 0), Color.WHITE, new Point(0,
            getHeight()), Color.PINK.darker()));
      g2.fillRoundRect(0, 0, getWidth(), getHeight(), 30, 30);
      g2.setPaint(Color.BLACK);
      g2.drawString(getText(), 30, 12);
      g2.dispose();

      // super.paintComponent(g);
   }
