The code is more understandable if the setTopComponent() and setBottomComponent() methods are
used with better variable names: |
|
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JSplitPane;
public class JSplitPaneVerticalSetTopBottom {
public static void main(String[] a) {
JFrame horizontalFrame = new JFrame();
horizontalFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JComponent topButton = new JButton("Left");
JComponent bottomButton = new JButton("Right");
JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
splitPane.setTopComponent(topButton);
splitPane.setBottomComponent(bottomButton);
horizontalFrame.add(splitPane, BorderLayout.CENTER);
horizontalFrame.setSize(150, 150);
horizontalFrame.setVisible(true);
}
}
