Position buttons vertically one after another using the Box class. Use the createVerticalBox() method that displays components from top to bottom −
JButton button1 = new JButton("One"); JButton button2 = new JButton("Two"); JButton button3 = new JButton("Three"); Box box = Box.createVerticalBox(); box.add(button1); box.add(button2); box.add(button3);
The following is an example to position buttons vertically one after another −
package my; import javax.swing.Box; import javax.swing.JButton; import javax.swing.JFrame; public class SwingDemo { public static void main(String[] args) { JButton button1 = new JButton("One"); JButton button2 = new JButton("Two"); JButton button3 = new JButton("Three"); JButton button4 = new JButton("Four"); JButton button5 = new JButton("Five"); JButton button6 = new JButton("Six"); JButton button7 = new JButton("Seven"); Box box = Box.createVerticalBox(); box.add(button1); box.add(button2); box.add(button3); box.add(button4); box.add(button5); box.add(button6); box.add(button7); JFrame frame = new JFrame(); frame.add(box); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLocationByPlatform(true); frame.setSize(500, 300); frame.setVisible(true); } }
