GridBaglayout in Java

How to declare the Gridbaglayout class

Class GridBagLayout extends Object
Implements LayoutManager, Serializable

Constructor in gridBaglayout

GridBagLayout () is a GridBagLayout constructor that helps to create a grid architecture manager. First, we build a GridBagLayout class object with the help of a no-argument constructor.

GridBagLayout methods

There are various methods in GridBagLayout which are described below                      

Now let’s understand gridBaglayout in java with the help of some examples

Java GridBagLayout() constructor

//program to implement the GridBaglayout in java with constructor.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class SwingLayoutDemo 
{
   private JFrame mainFrame;
   private JLabel headerLabel;
   private JLabel statusLabel;
   private JPanel controlPanel;
   private JLabel msglabel;

     public SwingLayoutDemo()
     {
      preparingtable();
     }
     public static void main(String[] args)
     {
      SwingLayoutDemo swingLayoutDemo = new SwingLayoutDemo();  
      swingLayoutDemo.showGridBagLayoutDemo();       
     }
     private void preparingtable()
     {
      mainFrame = new JFrame("Java SWING Examples");
      mainFrame.setSize(400,400);
      mainFrame.setLayout(new GridLayout(3, 1));

      headerLabel = new JLabel("",JLabel.CENTER );
      statusLabel = new JLabel("",JLabel.CENTER);        
      statusLabel.setSize(350,100);
      
      mainFrame.addWindowListener(new WindowAdapter() 
      {
         public void windowClosing(WindowEvent windowEvent)
         {
            System.exit(0);
         }        
      });    
      controlPanel = new JPanel();
      controlPanel.setLayout(new FlowLayout());

      mainFrame.add(headerLabel);
      mainFrame.add(controlPanel);
      mainFrame.add(statusLabel);
      mainFrame.setVisible(true);  
   }
   private void showGridBagLayoutDemo()
   {
      JPanel panel = new JPanel();
      panel.setBackground(Color.darkGray);
      panel.setSize(300,300);
      GridBagLayout layout = new GridBagLayout();
      
      panel.setLayout(layout);        
      GridBagConstraints bag = new GridBagConstraints();

      bag.fill = GridBagConstraints.HORIZONTAL;
      bag.gridx = 0;
      bag.gridy = 10;
      panel.add(new JButton("Coding"),bag);

      bag.gridx = 50;
      bag.gridy = 10;
      panel.add(new JButton("Ninjas"),bag); 

      bag.fill = GridBagConstraints.HORIZONTAL;
      bag.ipady = 100;   
      bag.gridx = 50;
      bag.gridy = 10;
      panel.add(new JButton("Code"),bag); 
      
      bag.gridx = 150;
      bag.gridy = 20;       
      panel.add(new JButton("studio"),bag);  
              
      controlPanel.add(panel);
      mainFrame.setVisible(true);  
   }
}
