HELP: creating an Icon-only Button

Question

Hello!
I've got the following problem: I would like to create a Button that has the appearance of a 23x20 pixel icon that I've stored on the hard disk, i.e. no regular button body around the icon. I've reached some progress myself by extending the new class, OwnButton, from JButton and overriding the protected void paintComponent(Graphics g) method, but it doesn't really give the results I wish. The icon does paint itself correctly without anything else around it, but the area of the JFrame in which the button is placed is larger than the icon itself but is transparent. In other words, the button is bigger than the icon, and the icon is painted in the top left corner of the button, with the rest of the button being transparent. I've tried using the setMinimumSize, setPreferredSize, setMaximumSize and setSize methods of the OwnButton without success.
If anyone has any ideas about how to solve this problem, please share them with me. I'm very grateful for any hints.
Thank you,
MS

You don't need to subclass JButton. You can achieve what you want with the methods
setBorderPainted(false);
setIcon(myIcon);
setText(null);
