titled.setTitleFont(new Font("Verdana", 0, 13));
titled.setTitleColor(new Color(213, 225, 185));

voidapplyCorrectViewPosition(JComponent targetComponent, JScrollPane scrollPane)
apply Correct View Position 
try {
    Point point = new Point(0, (int) (targetComponent.getSize().getHeight()));
    JViewport vp = scrollPane.getViewport();
    if (vp == null) {
        return;

voidbindHorizontalScrolling(JScrollPane jScrollPane1, JScrollPane jScrollPane2)
bind Horizontal Scrolling 
jScrollPane2.getHorizontalScrollBar().setModel(jScrollPane1.getHorizontalScrollBar().getModel());
JScrollPanebuildLabeledScroller(String label, Component contents)
build Labeled Scroller 
JScrollPane ret = new JScrollPane(contents);
ret.setBorder(buildLabeledBorder(label));
return ret;
JScrollPanecreateJScrollPane(JComponent component)
create J Scroll Pane 
final JScrollPane scrollPane = new JScrollPane();
scrollPane.setViewportView(component);
return scrollPane;
JScrollPanecreateScrollPane(JComponent content)
creates a scrollpane with the given component embedded. 
JScrollPane scrollPane = new JScrollPane(content, ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED,
        ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
return scrollPane;
JScrollPanecreateSelfManagedScrollPane(final Component view, final JComponent parentToRevalidate)
Creates and returns a scroll panel which wraps the specified view component.
The returned scroll panel disables vertical scroll bar, and only displays the horizontal scroll bar when the view does not fit into the size of the view port. 
final JScrollPane scrollPane = new JScrollPane(view);
scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_NEVER);
scrollPane.getHorizontalScrollBar().setPreferredSize(new Dimension(0, 12)); 
scrollPane.getHorizontalScrollBar().setUnitIncrement(10);
final ComponentListener scrollPaneComponentListener = new ComponentAdapter() {
    @Override
    public void componentResized(final ComponentEvent event) {
        scrollPane.setHorizontalScrollBarPolicy(
