This is an example on how to create a new JSplitPane
component for a Java Desktop Application.The JSplitPane
is commonly used component because it lets you split your window horizontally or vertically in order to create a wide variety of GUI elements to suit your application’s needs.
In short in order to create a JSplitPane
component in Java, one should follow these steps:
- Create a new
JFrame
. - Call
frame.getContentPane().setLayout(new FlowLayout())
to set flow layout for the frame. - Create two String arrays that will containt the contents of the two areas of the
JSplitPane
. - Create two
JScrollPane
components. - Create a new
JSplitPane
with the aboveJScrollPane
components in each side. - Use
frame.getContentPane().add(splitPane)
to add the spilt pane to your frame

import javax.swing.JFrame;
import javax.swing.JSplitPane;
public class CreateJSplitPaneExample {
private static void createAndShowGUI() {
// Create and set up the window.
final JFrame frame = new JFrame("Split Pane Example");
// Display the window.
frame.setSize(200, 200);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// set flow layout for the frame
frame.getContentPane().setLayout(new FlowLayout());
String[] options1 = { "Bird", "Cat", "Dog", "Rabbit", "Pig" };
JComboBox combo1 = new JComboBox(options1);
String[] options2 = { "Car", "Motorcycle", "Airplane", "Boat" };
JComboBox combo2 = new JComboBox(options2);
Panel panel1 = new Panel();
panel1.add(combo1);
Panel panel2 = new Panel();
panel2.add(combo2);
JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, panel1, panel2);
// JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT, panel1, panel2);
frame.getContentPane().add(splitPane);
}
public static void main(String[] args) {
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}
