セクシーなオン/オフスライダーを追加するには？

私は、Javaアプリケーションでオン/オフのようなトグルスイッチを追加したいと思います。 Swing Slidersからそれらを構築する必要がありますか、それとも既に近いものがありますか？ JScrollBarのを使用して、多分

、ここだけと未完了のアイデアはあなたに

import java.awt.*; 
import java.awt.event.AdjustmentEvent; 
import java.awt.event.AdjustmentListener; 
import javax.swing.*; 
import javax.swing.event.ChangeEvent; 
import javax.swing.event.ChangeListener; 

public class Sliders { 

    private JFrame frame; 
    private JPanel main; 
    private JPanel scrollBarPanel = new JPanel(); 
    private JPanel sliderPanel; 

    public Sliders() { 
     frame = new JFrame(); 
     main = new JPanel(new GridLayout(2, 1)); 
     final JScrollBar scrollBar = new JScrollBar(JScrollBar.HORIZONTAL, 0, 100, 0, 200); 
     int height = scrollBar.getPreferredSize().height; 
     scrollBar.setPreferredSize(new Dimension(175, height)); 
     scrollBarPanel.add(scrollBar); 
     main.add(scrollBarPanel); 
     sliderPanel = new JPanel(); 
     final JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 255, 128); 
     slider.setMajorTickSpacing(48); 
     slider.setMinorTickSpacing(16); 
     slider.setPaintTicks(true); 
     sliderPanel.add(slider); 
     main.add(sliderPanel); 
     frame.add(main, BorderLayout.CENTER); 
     scrollBar.addAdjustmentListener(new AdjustmentListener() {

組み込みコンポーネントJCheckBoxを使用します。

JCheckBox cb = new JCheckBox(createImageIcon("off-image.gif", "Click To Turn On")); 
cb.setSelectedIcon(createImageIcon("on-image.gif", "Click To Turn Off"));

ほんの少しの例ですが、おそらくそれが役に立ちます。

public class Popup extends JFrame { 

    public Popup() { 
     setBounds(100, 100, 300, 120); 
     setDefaultCloseOperation(3); 
     getContentPane().setLayout(new FlowLayout(FlowLayout.LEADING, 10, 10)); 
     getContentPane().add(new JSwitchBox("on", "off")); 
     getContentPane().add(new JSwitchBox("yes", "no")); 
     getContentPane().add(new JSwitchBox("true", "false")); 
     getContentPane().add(new JSwitchBox("on", "off")); 
     getContentPane().add(new JSwitchBox("yes", "no")); 
     getContentPane().add(new JSwitchBox("true", "false")); 
    } 

    public static void main(String[] args) { 
     SwingUtilities.invokeLater(new Runnable() { 
      @Override 
      public void run() { 
       new Popup().setVisible(true);
