Method

JPanelbuildComponentPanel(JComponent component, int hgap, int vgap, boolean isOpaque)
Adds the specified JComponent to a JPanel with a left flow layout. 
JPanel p = new JPanel();
if (component == null)
    return p;
if (hgap < 0)
    hgap = 0;
if (vgap < 0)
    vgap = 0;
p.setLayout(new FlowLayout(FlowLayout.LEFT, hgap, vgap));
...
JPanelbuildComponentPanelRight(JComponent component, int hgap, int vgap, boolean isOpaque)
Adds the specified JComponent to a JPanel with a right flow layout. 
JPanel p = new JPanel();
if (component == null)
    return p;
if (hgap < 0)
    hgap = 0;
if (vgap < 0)
    vgap = 0;
p.setLayout(new FlowLayout(FlowLayout.RIGHT, hgap, vgap));
...
voiddisableAll(JComponent component)
disable All 
component.setEnabled(false);
for (Component cmp : component.getComponents()) {
    if (cmp instanceof JComponent) {
        disableAll((JComponent) cmp);
voiddisposeParentWindow(JComponent component)
dispose Parent Window 
Window window = SwingUtilities.windowForComponent(component);
if (window != null)
    window.dispose();
voiddoDisable(JComponent component)
do Disable 
if (component.isEnabled())
    component.setEnabled(false);
MapgetProperties(JComponent component)
Convenience method for obtaining most non-null human readable properties of a JComponent. 
Map<Object, Object> retVal = new HashMap<Object, Object>();
Class<?> clazz = component.getClass();
Method[] methods = clazz.getMethods();
Object value = null;
for (Method method : methods) {
    if (method.getName().matches("^(is|get).*") && method.getParameterTypes().length == 0) {
        try {
            Class returnType = method.getReturnType();
...
MapgetProperties(JComponent component)
Convenience method for obtaining most non-null human readable properties of a JComponent. 
Class<?> clazz = component.getClass();
Method[] methods = clazz.getMethods();
Map<Object, Object> retVal = new HashMap<>(methods.length);
Object value = null;
for (Method method : methods) {
    if (method.getName().matches("^(is|get).*") && (method.getParameterTypes().length == 0)) {
        try {
            Class<?> returnType = method.getReturnType();
...
MapgetProperties(JComponent component)
Convenience method for obtaining most non-null human readable properties of a JComponent. 
Map<Object, Object> retVal = new HashMap<>();
Class<?> clazz = component.getClass();
Method[] methods = clazz.getMethods();
Object value = null;
for (Method method : methods) {

        try {
            Class<?> returnType = method.getReturnType();
...
RectanglegetVisibleBoundsOnScreen(JComponent component)
Returns the specified component's visible bounds within the screen. 
Rectangle visibleRect = component.getVisibleRect();
Point onScreen = visibleRect.getLocation();
SwingUtilities.convertPointToScreen(onScreen, component);
visibleRect.setLocation(onScreen);
return visibleRect;
voidinvert(JComponent c)

Makes a Swing component inverted by swapping its foreground and background colors. 

Color invBackground = c.getForeground();
Color invForeground = c.getBackground();
c.setBackground(invBackground);
c.setForeground(invForeground);
