button background color

[new2java2009]

I have a button on a frame, which I like the background color to behave as follow with the mouse:
1. When the mouse is over the button, I like it to be "buttonHighlightColor".
2. when the mouse is pressed (hold, not release yet), I like the color to be "buttonDownColor".
3. When the mouse is release, but the mouse is still on the button, I like the color to be "buttonHighlightColor".
4. When the mouse leaves the button, I like the color to change to "buttonUpColor".

I used the following code, everything works fine, but 2 doesn't work.

I expect that while I am holding my mouse (mousePressed), the button color would be "buttonDownColor", but it's not. It's the default light blue color.

Can someone tell me what I am doing wrong, and how to fix it? Following is my code.

Thanks!

import java.awt.Color;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.JButton;
import javax.swing.JFrame;

class MouseTest {
	public static void main(String[] args) {
		MouseListener popup;
		final Color buttonDownColor = new Color(72, 63, 48);
		final Color buttonHighlightColor = new Color(112, 98, 72);
		final Color buttonUpColor = new Color(79, 70, 54);

		JFrame frame = new JFrame();
    
		final JButton button = new JButton("Test How The Mouse Works");
		button.setBackground(buttonUpColor);
    
		popup = new MouseListener() {
			public void mouseClicked(MouseEvent e) {
			}

		     public void mouseEntered(MouseEvent e) {
		    	 button.setBackground(buttonHighlightColor);
		     }
		
		     public void mouseExited(MouseEvent e) {
		    	 button.setBackground(buttonUpColor);
		     }
		
		     public void mousePressed(MouseEvent e) {
		    	 button.setBackground(buttonDownColor);
		     }

		     public void mouseReleased(MouseEvent e) {
		    	 button.setBackground(buttonHighlightColor);
		     }
		};
		button.addMouseListener(popup);
		frame.add(button);
		frame.setSize(300, 300);
		frame.setVisible(true);

	}
}

The ButtonUI does some custom painting that ignores the background color when the button is pressed.

Change you code as follows to see how it works for a JLabel:

//        final JButton button = new JButton("Test How The Mouse Works");
        final JLabel button = new JLabel("Test How The Mouse Works");
        button.setOpaque(true);
