In this tutorials, we are going to implement a simple Java project using Swing JSplitPane and JList.
Swing JSplitPane :
SplitPaneDemo.java
package com.swing.examples;
import java.awt.Container;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JList;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JSplitPane;
import javax.swing.JTextArea;
import javax.swing.event.ListSelectionEvent;
import javax.swing.event.ListSelectionListener;
public class SplitPaneDemo extends JFrame {
JSplitPane splitPane, mainSplitPane;
JList list;
JPanel listPanel, imagePanel;
JLabel img;
Container contentPane;
String listData[] = {"duke","duke.running","duke2","dukeMagnify","dukeplug","dukeSnooze","dukeWave","dukeWaveRed","cow"};
JTextArea textArea;
SplitPaneDemo(){
super("SplitPane Demo !");
list = new JList(listData);
list.addListSelectionListener(new ListSelectionListener() {
@Override
public void valueChanged(ListSelectionEvent e) {
textArea.setText("This is : "+list.getSelectedValue());
//Local Images path
img.setIcon(new ImageIcon("C:\\images\\"+list.getSelectedValue()+".gif"));
}
});
textArea = new JTextArea(4,30);
// Adding ListPanel
listPanel = new JPanel();
listPanel.add(list);
// Adding Image Pannel
img = new JLabel();
imagePanel = new JPanel();
imagePanel.add(img);
// Creating SplitPanel
splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,false,new JScrollPane(listPanel),imagePanel);
splitPane.setDividerSize(10);
splitPane.setOneTouchExpandable(true);
mainSplitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT,splitPane,new JScrollPane(textArea));
mainSplitPane.setDividerSize(10);
mainSplitPane.setDividerLocation(150);
contentPane = getContentPane();
contentPane.add(mainSplitPane);
setSize(400, 275);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
new SplitPaneDemo();
}
}
Output :
Selecting the JList and performing an action.
Happy Learning 🙂
