Java JSlider mit JChangeListener

Ein Java JSlider verfügt über einen ChanceListener, welcher immer ausgelöst wird, wenn Man den Slider bewegt. Hier ein kleines Beispiel dazu.

package view;
 
import java.awt.BorderLayout;
 
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JSlider;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
 
public class ViewJSlider extends JFrame implements ChangeListener {
 
    private static final long serialVersionUID = 1L;
    private int jSliderWert = 10;
    private JLabel label = new JLabel(Integer.toString(this.jSliderWert));
    private JSlider slider = new JSlider(0, 100, this.jSliderWert);
     
    public ViewJSlider(){
        this.setTitle("JSlider Beispiel");
        this.setBounds(100,100,300, 200);
        this.setLayout(new BorderLayout());
        this.add(label, BorderLayout.NORTH);
        this.slider.addChangeListener(this);
        this.add(slider, BorderLayout.CENTER);
        this.setVisible(true);
    }
 
    @Override
    public void stateChanged(ChangeEvent arg0) {
        if(arg0.getSource() == this.slider){
            this.jSliderWert = ((JSlider) arg0.getSource()).getValue();
            this.label.setText(Integer.toString(this.jSliderWert));
        }
         
    }
 
}

package view;

import java.awt.BorderLayout;

import javax.swing.JFrame;

import javax.swing.JLabel;

import javax.swing.JSlider;

import javax.swing.event.ChangeEvent;

import javax.swing.event.ChangeListener;

public class ViewJSlider extends JFrame implements ChangeListener {

private static final long serialVersionUID = 1L;

private int jSliderWert = 10;

private JLabel label = new JLabel(Integer.toString(this.jSliderWert));

private JSlider slider = new JSlider(0, 100, this.jSliderWert);

public ViewJSlider(){

this.setTitle("JSlider Beispiel");

this.setBounds(100,100,300, 200);

this.setLayout(new BorderLayout());

this.add(label, BorderLayout.NORTH);

this.slider.addChangeListener(this);

this.add(slider, BorderLayout.CENTER);

this.setVisible(true);

}

@Override

public void stateChanged(ChangeEvent arg0) {

if(arg0.getSource() == this.slider){

this.jSliderWert = ((JSlider) arg0.getSource()).getValue();

this.label.setText(Integer.toString(this.jSliderWert));

}
