voidnumberButtonGroup(ButtonGroup buttonGroup)
number Button Group 
int entry = 0;
Enumeration<AbstractButton> buttons = buttonGroup.getElements();
while (buttons.hasMoreElements()) {
    AbstractButton button = buttons.nextElement();
    button.setActionCommand(Integer.toString(entry++));
voidopacityCheck(AbstractButton b)
Sets the opacity of the specified button depending on the system look and Feel. 
if (b == null)
    return;
b.setContentAreaFilled(!isMacOS());
voidpaintClassicText(AbstractButton b, Graphics g, int x, int y, String text, int mnemIndex)
paint Classic Text 
ButtonModel model = b.getModel();
Color color = b.getForeground();
if (model.isEnabled()) {
    if (!(b instanceof JMenuItem && model.isArmed())
            && !(b instanceof JMenu && (model.isSelected() || model.isRollover()))) {
        g.setColor(b.getForeground());
    SwingUtilities2.drawStringUnderlineCharAt(b, g, text, mnemIndex, x, y);
...
intparseLevel(ButtonGroup buttonGroup)
parse Level 
Enumeration<AbstractButton> buttonEnumeration = buttonGroup.getElements();
while (buttonEnumeration.hasMoreElements()) {
    AbstractButton abstractButton = buttonEnumeration.nextElement();
    if (abstractButton.isSelected()) {
        String buttonText = abstractButton.getText();
        final int index = buttonText.indexOf(" (");
        if (index != -1) {
            buttonText = buttonText.substring(0, index);
...
voidremoveAllActionListeners(AbstractButton btn)
removes all action listeners from the given button 
for (ActionListener al : btn.getActionListeners()) {
    btn.removeActionListener(al);
voidremoveButtonBorder(AbstractButton button)
Removes the button border. 
button.setContentAreaFilled(false);
button.setMargin(new Insets(0, 0, 0, 0));
button.setBorder(BorderFactory.createEmptyBorder());
voidremoveCloseButton(Component comp)
Only works for default look and feel, where Swing creates a real close button. 
if (comp instanceof JMenu) {
    Component[] children = ((JMenu) comp).getMenuComponents();
    for (int i = 0; i < children.length; ++i) {
        removeCloseButton(children[i]);
} else if (comp instanceof AbstractButton) {
    Action action = ((AbstractButton) comp).getAction();
    String cmd = (action == null) ? "" : action.toString();
...
ActionListener[]removeListeners(AbstractButton button)
Removes the listeners from the given AbstractButton 
ActionListener[] listeners = button.getActionListeners();
for (int i = 0; i < listeners.length; i++) {
    button.removeActionListener(listeners[i]);
return listeners;
voidscaleAllAbstractButtonIconsOf(Container container, int size)
Resizes the icons of all the abstract buttons which are contained in a container. 
for (final Component c : container.getComponents()) {
    if (c instanceof AbstractButton) {
        final ImageIcon i = (ImageIcon) ((AbstractButton) c).getIcon();
        if (i != null) {
            i.setImage(i.getImage().getScaledInstance(size, size, Image.SCALE_SMOOTH));
IconscaleButtonIcon(Icon icon, int size)
scale Button Icon 
Icon result = icon;
if (icon != null) {
    int h = icon.getIconHeight();
    if ((size > (1.0 + ICON_SCALE_THRESHOLD) * h) || (size < (1.0 - ICON_SCALE_THRESHOLD) * h)) {
        int w = icon.getIconWidth();
        BufferedImage image = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
        icon.paintIcon(new JButton(), image.getGraphics(), 0, 0);
        double ratio = (h == 0) ? 0.0 : (double) w / (double) h;
