JScrollPane scrollbar color

You could try

class MyScrollBarUI extends BasicScrollBarUI {

// this draws scroller

protected void paintThumb(Graphics g, JComponent c, Rectangle thumbBounds) {

g.setColor(Color.BLUE);

g.fillRect((int)trackBounds.getX(),(int)trackBounds.getY(),

(int)trackBounds.getWidth(),(int)trackBounds.getHeight());

}

// this draws scroller background

protected void paintTrack(Graphics g, JComponent c, Rectangle trackBounds) {

g.setColor(Color.RED);

g.fillRect((int)trackBounds.getX(),(int)trackBounds.getY(),

(int)trackBounds.getWidth(),(int)trackBounds.getHeight());

}

// and methods creating scrollbar buttons

protected JButton createDecreaseButton(int orientation) {

JButton button = super.createDecreaseButton(orientation);

button.setBackground(Color.BLACK);

button.setBorder(BorderFactory.createLineBorder(Color.WHITE, 1));

return button;

}

protected JButton createIncreaseButton(int orientation) {

JButton button = super.createIncreaseButton(orientation);

button.setBackground(Color.BLACK);

button.setBorder(BorderFactory.createLineBorder(Color.WHITE, 1));

return button;

}

}

...and when you create JScrollPane, to modify let's say vertical scrollbar, simply call --

scrollPane.getVerticalScrollBar().setUI(new MyScrollBarUI());
