Method

JSplitPanegetSplitPane(boolean vertical, JComponent left, JComponent right)
Helper that creates a SplitPane 
JSplitPane result = new JSplitPane(vertical ? JSplitPane.VERTICAL_SPLIT : JSplitPane.HORIZONTAL_SPLIT, left,
        right);
result.setDividerSize(3);
result.setDividerLocation(0.5D);
return result;
doublegetSplitPaneComponentLength(JSplitPane splitPane, Component component)
get Split Pane Component Length 
Dimension size = component.getPreferredSize();
return (splitPane.getOrientation() == JSplitPane.HORIZONTAL_SPLIT) ? size.getWidth() : size.getHeight();
intgetSplitPaneSize(JSplitPane splitPane)
get Split Pane Size 
if (splitPane == null) {
    return 0;
boolean horiz = splitPane.getOrientation() == JSplitPane.HORIZONTAL_SPLIT ? true : false;
return horiz ? splitPane.getWidth() : splitPane.getHeight();
JSplitPanehsplit(Component left, Component right, double resizeWeight)
Create a horizontally aligned JSplitPane 
JSplitPane split = hsplit(left, right);
split.setResizeWeight(resizeWeight);
return split;
floatrememberOldHeightRatio(JSplitPane splitPane)
remember Old Height Ratio 
int oldHeight = splitPane.getHeight();
float oldFraction = ((oldHeight == 0) ? 0 : ((float) splitPane.getDividerLocation()) / oldHeight);
return oldFraction;
voidsanitizeSplitPaneDivider(JSplitPane splitPane)
sanitize Split Pane Divider 
Component firstComponent = splitPane.getLeftComponent();
Component secondComponent = splitPane.getRightComponent();
double firstLength = getSplitPaneComponentLength(splitPane, firstComponent);
double secondLength = getSplitPaneComponentLength(splitPane, secondComponent);
double preferredWeight = firstLength / (firstLength + secondLength);
splitPane.setResizeWeight(preferredWeight);
JSplitPanesetDividerLocation(final JSplitPane splitter, final int position)
Force divider location for a JSplitPan with int position. 
if (splitter.isShowing()) {
    if (splitter.getWidth() > 0 && splitter.getHeight() > 0) {
        splitter.setDividerLocation(position);
    } else {
        splitter.addComponentListener(new ComponentAdapter() {
            @Override
            public void componentResized(ComponentEvent ce) {
                splitter.removeComponentListener(this);
...
voidsetNewHeightRatio(JSplitPane splitPane, JComponent comp, float oldFraction, int v1, int v2)
set New Height Ratio 
int h = comp.getHeight();
splitPane.setDividerLocation(
        (int) ((oldFraction <= 0.01) ? v1 * h / v2 : splitPane.getHeight() * oldFraction));
voidsetSplitDivider(final JSplitPane split, float proportion)
Moves the supplied JSplitPane divider to the specified proportion. 
if (split == null) {
    return;
proportion = Math.max(0f, proportion);
final float percent = Math.min(1f, proportion);
int size = getSplitPaneSize(split);
if (split.isVisible() && size > 0 && EventQueue.isDispatchThread()) {
    split.setDividerLocation(proportion);
...
voidsetSplitPaneDividerColor(final JSplitPane pane, final Color color)
Change the colour of a JSplitPane divider. 
final SplitPaneUI splitUI;
splitUI = pane.getUI();
if (splitUI instanceof BasicSplitPaneUI) {
    final BasicSplitPaneDivider divider;
    divider = ((BasicSplitPaneUI) splitUI).getDivider();
    if (divider != null) {
        final Border divBorder;
        final Border newBorder;
