Or maybe my JPanel is not appearing at all.
I am trying to have a JPanel at the bottom of the screen that hold several buttons. Can someone set me strait?
public class MyAWTMenu extends java.awt.Frame// implements ActionListener
{
public void init() {
setBackground( Color.white );
JPanel bottom = new JPanel();
bottom.setBackground(Color.BLACK);
JButton b1 = new JButton("test");
b1.setVisible(true);
bottom.add(b1);
bottom.setVisible(true);
add(bottom,BorderLayout.CENTER);
}
public static void main( String args [] ) {
MyAWTMenu objAppFrame = new MyAWTMenu();
objAppFrame.addWindowListener( //Register an anonymous class as a listener.
new WindowAdapter() {
public void windowClosing( WindowEvent e )
{
System.exit( 0 );
}
}
);
objAppFrame.init();
objAppFrame.setSize( 760, 378);
objAppFrame.setVisible( true );
}
I'd better rewrite it as follows:
public class FooFrame extends JFrame {
public FooFrame() {
// your code, copy/pasted
setBackground(Color.white);
JPanel bottom = new JPanel();
bottom.setBackground(Color.BLACK);
JButton b1 = new JButton("test");
bottom.add(b1);
add(bottom, BorderLayout.CENTER);
// set size & pack
Dimension size = new Dimension(400, 400);
setPreferredSize(size);
setMinimumSize(size);
pack();
setLocationRelativeTo(null);
}
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new FooFrame().setVisible(true);
}
});
}
}
add(bottom,BorderLayout.SOUTH);
in your init()
Here's your code that i was running. It seems to work fine for me. I did add a call to pack();
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JButton;
import javax.swing.JPanel;
public class MyAWTMenu extends java.awt.Frame// implements ActionListener
{
public void init() {
setBackground(Color.white);
JPanel bottom = new JPanel();
bottom.setBackground(Color.BLACK);
JButton b1 = new JButton("test");
bottom.add(b1);
bottom.setVisible(true);
add(bottom, BorderLayout.SOUTH);
pack();
}
public static void main(String args[]) {
MyAWTMenu objAppFrame = new MyAWTMenu();
objAppFrame.addWindowListener( //Register an anonymous class as a listener.
new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
objAppFrame.init();
objAppFrame.setSize(760, 378);
objAppFrame.setVisible(true);
}
}
