hello, i am trying to link to class files. one is called menu1.java and one is called Trialgrid.java. menu1.java is a menu screen that has a utton called btn1PlayerButton and it is used to open Trialgrid.java file!!
my problem is i can't get the contents of my page to actually display, i can only seem to add one item (eg. a button) and not that whole program?? can anyone help??
here is my code for the menu1.java file:-
import javax.swing.* ;
import javax.swing.event.* ;
import java.awt.* ;
import java.awt.event.* ;
publicclass Menu1 implements ActionListener {
public Menu1 ()
{
}
privatestaticvoid createAndShowGUI (Menu1 paul)
{
JFrame frame = new JFrame ("Welcome to BattleShips");
Container content = frame.getContentPane();
content.setLayout (new BorderLayout());
JButton btn1PlayerButton = new JButton ("One Player");
JButton btnRules = new JButton ("Rules");
JButton btnExit = new JButton ("Exit");
Dimension menuButtonSize = new Dimension(110, 25);
JLabel lblTitle = new JLabel ("Battleships 3000");
JLabel lbl1PlayerGame = new JLabel ("Click to start a one player game");
JLabel lblRules = new JLabel ("To see the rules click here");
JLabel lblExit = new JLabel ("Exit the program");
JPanel north = new JPanel();
north.setPreferredSize(new Dimension(110,115));
north.add(lblTitle);
lblTitle.setForeground(Color.blue);
content.add(north, BorderLayout.NORTH);
JPanel center = new JPanel();
JPanel jp = new JPanel();
jp.setPreferredSize(new Dimension(160,25)); // Used to create a blank space in menu
center.add(jp);
content.add(center, BorderLayout.CENTER);
JPanel west = new JPanel();
west.setLayout(new BorderLayout());
JPanel wNorth = new JPanel();
JPanel wCenter = new JPanel();
JPanel wSouth = new JPanel();
wSouth.setPreferredSize(new Dimension(110,115));

}
publicvoid actionPerformed (ActionEvent ae)
{
/*Object source = ae.getSource();
if (source == btn1PlayerButton)
{*/
TrialGrid grid = new TrialGrid () ;
grid.showGrid () ;
//}
/*if (souce == btnExit)
{
System.exit(0);
}*/
}
publicstaticvoid main (String[] args)
{
javax.swing.SwingUtilities.invokeLater(new Runnable() {

});
}
}
