How to change the color or background color of JSplitPane divider?

问题

I am trying to the set the background color for the JSplitPane divider. I've written the following code, but it doesn't seem to work.

        BasicSplitPaneUI ui = (BasicSplitPaneUI) splitPane.getUI();
        BasicSplitPaneDivider divider = ui.getDivider();
        divider.setBackground(Color.decode("#FFFACD"));

I've even tried the suggestion given here How to set BackGround color to a divider in JSplitPane

Can someone please point out the mistake or let me know any other approach?

This works for me

BasicSplitPaneDivider divider = (BasicSplitPaneDivider) splitPane.getComponent(2);
divider.setBackground(Color.black);
divider.setBorder(null);

I searched for many post for changing the divider color of split pane. And i did found the solution for it.

splitPane.setUI(new BasicSplitPaneUI() 
{
    @Override
    public BasicSplitPaneDivider createDefaultDivider() 
    {
        return new BasicSplitPaneDivider(this) 
        {                
            public void setBorder(Border b) {}

            @Override
            public void paint(Graphics g) 
            {
                g.setColor(Color.BLACK);
                g.fillRect(0, 0, getSize().width, getSize().height);
                super.paint(g);
            }
        };
    }
});

splitPane.setBorder(null);

With the above code,we can set the color,set the border for the divider too.For more information,refer this tutorial

What Look and Feel are you using? The LaF can and often does override what you may set.
