package Menuprincipal; 

import java.awt.BorderLayout; 
import java.awt.Color; 
import java.awt.Dimension; 
import java.awt.GridLayout; 
import javax.swing.JButton; 
import javax.swing.JFrame; 
import javax.swing.JPanel; 


public class Fenetre extends JFrame{ 

private JButton nouveauButton, loadButton, objectifButton, quitButton;


public Fenetre(){ 
this.setTitle("MENU"); 
this.setSize(500, 600); 
this.setLocationRelativeTo(null); 



this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
this.setResizable(false); 
JPanel pan = new JPanel(); 
pan.setBackground (Color.green); 
this.setContentPane(pan); 

GridLayout gl = new GridLayout(4,0); 
gl.setVgap(50); 
this.setLayout(gl);

nouveauButton = new JButton("Nouvelle partie");
nouveauButton.setPreferredSize(new Dimension(150, 120));

idem pour les autres boutons ... ensuite 

this.getContentPane().add (nouveauButton);
this.getContentPane().add (loadButton);
this.getContentPane().add (objectifButton); 
this.getContentPane().add (quitButton); 
this.setVisible(true); 
} 
}
