Dear All,
I am a bit puzzled as to how to accomplish a task that looks simple. I
have two Jframes and each of them contains a button. I want to be able
to hide the one that has the button I click on and show the other. I
wrote the following code for that:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class ButtonQuitter extends JFrame implements ActionListener
{
JButton bQuit = new JButton("Click here to Exit");
public ButtonQuitter()
{
getContentPane().setLayout( new FlowLayout() );
bQuit.addActionListener( this );
getContentPane().add( bQuit );
}
public static void newGui(){
ButtonQuitter frame = new ButtonQuitter();
ButtonQuitter frame12 = new ButtonQuitter();
frame.setSize( 200, 150 );
frame.setVisible( true );
frame12.setSize( 200, 150 );
frame12.setVisible( false );
}
public void actionPerformed( ActionEvent evt)
{
this.setVisible(false);
frame12.setVisible(true);
}
public static void main ( String[] args )
{
newGui();
}
}
However, when I run it, it complains that frame12 can not be resolved.
Could someone please offer some suggestions as to how to proceed?
Many Thanks,
George
