Im trying to use the following code to eventually make a game. The code, as shown below, works.
import java.awt.event.*;
import javax.swing.*;
public class GUI extends JFrame implements ActionListener
{
public static void main(String[] args)
{
GUI g = new GUI();
}
public GUI()
{
try
{
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e)
{
e.printStackTrace();
}
setSize(500,500);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setJMenuBar(createMenuBar());
setVisible(true);
}
public JMenuBar createMenuBar()
{
JMenuBar menuBar = new JMenuBar();
JMenu fileMenu = new JMenu("File");
fileMenu.setMnemonic(KeyEvent.VK_F);
JMenuItem save = new JMenuItem("Save");
save.setMnemonic(KeyEvent.VK_S);
save.addActionListener(this);
JMenuItem load = new JMenuItem("Load");
load.setMnemonic(KeyEvent.VK_L);
load.addActionListener(this);
JMenuItem quit = new JMenuItem("Quit");
quit.setMnemonic(KeyEvent.VK_Q);
quit.addActionListener(this);
fileMenu.add(save);
fileMenu.add(load);
fileMenu.addSeparator();
fileMenu.add(quit);
JMenu editMenu = new JMenu("Edit");
editMenu.setMnemonic(KeyEvent.VK_E);
JMenuItem undo = new JMenuItem("Undo");
undo.setMnemonic(KeyEvent.VK_U);
undo.addActionListener(this);
JMenuItem redo = new JMenuItem("Redo");
redo.setMnemonic(KeyEvent.VK_R);
redo.addActionListener(this);
editMenu.add(undo);
editMenu.add(redo);
JMenu helpMenu = new JMenu("Help");
helpMenu.setMnemonic(KeyEvent.VK_H);
JMenuItem controls = new JMenuItem("Controls");
controls.setMnemonic(KeyEvent.VK_C);
controls.addActionListener(this);
JMenuItem about = new JMenuItem("About");
about.setMnemonic(KeyEvent.VK_A);
about.addActionListener(this);
helpMenu.add(controls);
helpMenu.addSeparator();
helpMenu.add(about);
menuBar.add(fileMenu);
menuBar.add(editMenu);
menuBar.add(helpMenu);
return menuBar;
}
public void actionPerformed(ActionEvent e)
{
System.out.println(e.getActionCommand());
}
}
However, if you were to put a paint method in it, as shown below, it stops showing the JMenuBar.
import java.awt.event.*;
import javax.swing.*;
public class GUI extends JFrame implements ActionListener
{
public static void main(String[] args)
{
GUI g = new GUI();
}
public GUI()
{
try
{
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e)
{
e.printStackTrace();
}
setSize(500,500);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setJMenuBar(createMenuBar());
setVisible(true);
}
public JMenuBar createMenuBar()
{
JMenuBar menuBar = new JMenuBar();
JMenu fileMenu = new JMenu("File");
fileMenu.setMnemonic(KeyEvent.VK_F);
JMenuItem save = new JMenuItem("Save");
save.setMnemonic(KeyEvent.VK_S);
save.addActionListener(this);
JMenuItem load = new JMenuItem("Load");
load.setMnemonic(KeyEvent.VK_L);
load.addActionListener(this);
JMenuItem quit = new JMenuItem("Quit");
quit.setMnemonic(KeyEvent.VK_Q);
quit.addActionListener(this);
fileMenu.add(save);
fileMenu.add(load);
fileMenu.addSeparator();
fileMenu.add(quit);
JMenu editMenu = new JMenu("Edit");
editMenu.setMnemonic(KeyEvent.VK_E);
JMenuItem undo = new JMenuItem("Undo");
undo.setMnemonic(KeyEvent.VK_U);
undo.addActionListener(this);
JMenuItem redo = new JMenuItem("Redo");
redo.setMnemonic(KeyEvent.VK_R);
redo.addActionListener(this);
editMenu.add(undo);
editMenu.add(redo);
JMenu helpMenu = new JMenu("Help");
helpMenu.setMnemonic(KeyEvent.VK_H);
JMenuItem controls = new JMenuItem("Controls");
controls.setMnemonic(KeyEvent.VK_C);
controls.addActionListener(this);
JMenuItem about = new JMenuItem("About");
about.setMnemonic(KeyEvent.VK_A);
about.addActionListener(this);
helpMenu.add(controls);
helpMenu.addSeparator();
helpMenu.add(about);
menuBar.add(fileMenu);
menuBar.add(editMenu);
menuBar.add(helpMenu);
return menuBar;
}
public void paint(Graphics g)
{
}
public void actionPerformed(ActionEvent e)
{
System.out.println(e.getActionCommand());
}
}
Im not even kidding. Please help
