Create JList and always display the scroll bar in Java?
To always display the scroll bar in a JList, use the properties HORIZONTAL_SCROLLBAR_ALWAYS and VERTICAL_SCROLLBAR_ALWAYS:
JList list = new JList(sports); JScrollPane scrollPane = new JScrollPane(list); scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS); scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
The following is an example to create JList and display the scroll bar:
Example
package my;
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
class SwingDemo extends JFrame {
static JFrame frame;
static JList list;
public static void main(String[] args) {
frame = new JFrame("JList Demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
String sports[]= {"Tennis", "Archery","Football","Fencing","Cricket","Squash","Hockey","Rugby"};
list = new JList(sports);
JScrollPane scrollPane = new JScrollPane(list);
scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
frame.add(scrollPane);
frame.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG);
frame.setSize(400,100);
frame.setVisible(true);
}
}Output
