How to hide the track on the slider in Java?
To hide the track on the slider, you need to use the setPaintTrack() method and set it to FALSE −
JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 55); slider.setInverted(true); slider.setMinorTickSpacing(10); slider.setMajorTickSpacing(25); slider.setPaintTicks(true); slider.setPaintLabels(true); slider.setPaintTrack(false);
The above method setPaintTrack() is by default set to TRUE.
The following is an example to hide the track on the slider −

package my;
import java.awt.Color;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSlider;
import javax.swing.WindowConstants;
public class SwingDemo {
public static void main(String[] args) {
JFrame frame = new JFrame("Frame with Slider");
JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 55);
slider.setInverted(true);
slider.setMinorTickSpacing(10);
slider.setMajorTickSpacing(25);
slider.setPaintTicks(true);
slider.setPaintLabels(true);
slider.setBackground(Color.blue);
slider.setForeground(Color.white);
slider.setPaintTrack(false);
Font font = new Font("Serif", Font.BOLD, 20);
