import java.awt.Insets;
import javax.swing.ImageIcon;
import javax.swing.JButton;

public class ImageButton extends JButton {

    private static final long serialVersionUID = 7760427126786950870L;

    public ImageButton(ImageIcon icon) {
        setSize(icon.getImage().getWidth(null),icon.getImage().getHeight(null));
        setIcon(icon);
        setMargin(new Insets(0,0,0,0));
        setIconTextGap(0);
        setBorderPainted(false);
        setBorder(null);
        setText(null);

    }
}

稍微要解释一下的是讲button的边框都设置成为0，还有边框的重绘设置false，我们可以用不同的贴图表示按钮被选中等的状态

使用这个组件的demoCode

        ImageButton button = new ImageButton("images/*.png");
        button.setPressedIcon(new ImageIcon("images/*.png"));
        button.setRolloverIcon(new ImageIcon("images/*.png"));
        button.setSelectedIcon(new ImageIcon("images/*.png"));
        button.setRolloverSelectedIcon(new ImageIcon("images/*.png"));
        button.setDisabledIcon(new ImageIcon("images/*.png"));
        button.setDisabledSelectedIcon(new ImageIcon("images/*.png"));
