14. 87. 2. Creating a BoxLayout

BoxLayout has a single constructor:

public BoxLayout(Container target, int axis)

public BoxLayout(Container target, int axis)
  1. The first argument is the container
  2. The second is the layout direction.

Valid directions are

  1. BoxLayout.X_AXIS for a left-to-right layout and
  2. BoxLayout.Y_AXIS for a top-to-bottom layout.

A BoxLayout and container are bound together in two directions,

Creating a BoxLayout
import java.awt.LayoutManager;

import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class BoxLayoutDemo {

  public static void main(String[] a) {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JPanel panel = new JPanel();
    LayoutManager layout = new BoxLayout(panel, BoxLayout.X_AXIS);
    panel.setLayout(layout);

    panel.add(new JLabel("a"));
    panel.add(new JLabel("b"));
    panel.add(new JLabel("c"));
    panel.add(new JLabel("d"));
    panel.add(new JLabel("e"));
    panel.add(new JLabel("f"));

    frame.add(panel);

    frame.setSize(300200);
    frame.setVisible(true);
  }

}
