Struts in Java Swing Example

A strut is a fixed width invisible component that forces a certain amount of space between components. You can create a strut by calling the createHorizontalStrut () or createVerticalStrut () method depending upon what type of strut you want to create. The static method

createHorizontalStrut(int width)

creates a horizontal strut component that places the specified amount of space between the components on either side. The static method

createVerticalStrut(int Height)

creates a vertical strut component that places the specified amount of space between the components above and below it. For example : The following statements adds a vertical strut of 10 pixels between four buttons in a vertical box.

b.add(new JButton(“C”));

b.add(Box.createVerticalStrut(10));

b.add(new JButton(“C++”));

b.add(Box.createVerticalStrut(10));

b.add(new JButton(“Visual Basic”));

b.add(Box createVerticalStrut(10));

b. add (new JButton (“Java”));

import javax.swing.*; 
 import java.awt.*; 
 class BoxLayoutFrame extends JFrame 
 { 
      JButton [] Buttons; 
      BoxLayoutFrame() 
      { 
        int i; 
        Box b = Box.createVerticalBox(); 
        b.add(new JButton("C")); 
        b.add(Box.createVerticalStrut(10)); 
        b.add(new JButton("C++")); 
        b.add(Box.createVerticalStrut(10)); 
        b.add(new JButton("Visual Basic")); 
        b.add(Box.createVerticalStrut(10)); 
        b.add(new JButton("Java")); 
        add(b); 
      } 
 } 
    class StrutsJavaExample 
    { 
         public static void main(String args[]) 
        { 
             BoxLayoutFrame frame = new BoxLayoutFrame(); 
             frame.setTitle("Struts Java Example"); 
             frame.setBounds(200,250,200,200); 
             frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
             frame.setVisible(true); 
        } 
    }
