java设置滚动条透明度 java窗口滚动条

下面的程序可以将文本框添加到滚动条中。

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.BoundedRangeModel;
import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollBar;
import javax.swing.JTextField;
public class Main {
public static void main(String[] args) {
// TODO code application logic here
JFrame frame = new JFrame("Text Slider");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final JTextField textField = new JTextField();
JScrollBar scrollBar = new JScrollBar(JScrollBar.HORIZONTAL);
JPanel panel = new JPanel();
panel.setLayout(new BoxLayout(panel,BoxLayout.Y_AXIS));
BoundedRangeModel brm = textField.getHorizontalVisibility();
scrollBar.setModel(brm);
panel.add(textField);
panel.add(scrollBar);
// final TextSlider ts = new TextSlider();
textField.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
System.out.println("Text:"+textField.getText());
}
});
frame.add(panel,BorderLayout.NORTH);
frame.setSize(300,100);
frame.setVisible(true);
}
}

程序执行效果如图：
