The following example shows the effects of JLabel horizontal and vertical alignment:
import javax.swing.*; import java.awt.*; public class AlignmentExample { public static void main(String[] args) { // Create the labels and set alignment. JLabel label1 = new JLabel("BottomRight", SwingConstants.RIGHT); JLabel label2 = new JLabel("CenterLeft", SwingConstants.LEFT); JLabel label3 = new JLabel("TopCenter", SwingConstants.CENTER); label1.setVerticalAlignment(SwingConstants.BOTTOM); label2.setVerticalAlignment(SwingConstants.CENTER); label3.setVerticalAlignment(SwingConstants.TOP); // Add borders to the labels. label1.setBorder(BorderFactory.createLineBorder(Color.black)); label2.setBorder(BorderFactory.createLineBorder(Color.black)); label3.setBorder(BorderFactory.createLineBorder(Color.black)); // Put it all together. JFrame frame = new JFrame("AlignmentExample"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel p = new JPanel(new GridLayout(3, 1, 8, 8)); p.add(label1); p.add(label2); p.add(label3); p.setBorder(BorderFactory.createEmptyBorder(8, 8, 8, 8)); frame.setContentPane(p); frame.setSize(200, 200); frame.setVisible(true); } }
