I'm new at this NetBeans/Java stuff and appreciate the help.

How do I set the background color on my initial JFrame when creating a
GUI page? I went to the properties window and set the background
property and nothing seemed to happen. No problem setting the
background on JPanels object.

What I thought of was placing a "Master JPanel" that would cover the
complete JFrame.. Seems "Hookey" but maybe that's the correct way to
do what I want to do..

Thanks...

import java.awt.*;
import javax.swing.*;

public class test extends JFrame {
      public test() {
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          getContentPane().setBackground(Color.BLUE);
          setSize(400,300);
          setVisible(true);
      }

      public static void main(String[] args) {
          EventQueue.invokeLater(new Runnable() {
              public void run() {
                  new test();
              }
          });
      }

}

Thanks... Works like a charm... Appreciate the comeback...

Note that the content pane for a JFrame is in fact a JPanel.

put this line in to see;

System.out.println(getContentPane().getClass());
