swing JTable with ScrollBar - color of square between headers and track

Question

enter image description here

I have a JTable with BasicScrollBarUI, I set the headers background color: table.getTableHeader().setBackground(GuiConstants.backgroundColor);

and the scrolbar background color: public class ScrollBarUI extends BasicScrollBarUI {

@Override
protected void paintTrack(Graphics g, JComponent c, Rectangle trackBounds) {
    c.setBackground(GuiConstants.backgroundColor);

}

}

I still have a square between them that its color won't change. does anybody knows how to change it also to their color?

thanks

You could also just implement a custom `Look and Feel` for it. Haven't come across that issue before — Juxhin, Sep 07 '14 at 09:41
It's called a corner...take a look at [JScrollPane](http://docs.oracle.com/javase/7/docs/api/javax/swing/JScrollPane.html) — MadProgrammer, Sep 07 '14 at 10:17

As shown in How to Use Scroll Panes: Providing Custom Decorations, you can use the scroll pane's setCorner() method to add a colored Component:

JPanel panel = new JPanel();
panel.setBackground(Color.gray);
scrollPane.setCorner(JScrollPane.UPPER_RIGHT_CORNER, panel);

You may have to set the panel's opacity to true, and you may want to select a suitable color from the the current Look & Feel using the UIManager.
