java - How to add an image to JPanel that is in a JPanel?

itemprop="text">

I have 7
JPanel containers in total. I'd like to add a png image that I
generate, or buffer it with the help of the button(charger image) in the
JPanel(imagePan)

Most of the examples I've seen
so far in the Swing Tutorials use
ImageIcon

1. The
   images generated are at
   326X254


2. How to properly add
   an image to a panel?
   

Here you'll find the
code generating the window below:

            import java.awt.BorderLayout;
 import java.awt.Dimension;
 import
            java.awt.GridLayout;
 import java.io.IOException;
 import
            java.io.OutputStream;
 import java.io.PrintStream;


            import javax.swing.BorderFactory;
 import javax.swing.Box;
 import
            javax.swing.BoxLayout;
 import javax.swing.ImageIcon;
 import
            javax.swing.JButton;
 import javax.swing.JFrame;
 import
            javax.swing.JLabel;
 import javax.swing.JPanel;
 import
            javax.swing.JTextArea;
 import javax.swing.SwingUtilities;
 import
            javax.swing.border.Border;

How to proprely
add an image to a Jpanel?

1. Create
   an ImageIcon.


2. Add the icon to a
   JLabel.


3. Add the label to the
   JPanel.

Read
the section from the Swing tutorial on href="http://docs.oracle.com/javase/tutorial/uiswing/components/icon.html" rel="nofollow
noreferrer">How to Use Icons for more information and working
examples.

Also, from your posted code, get rid
of all the setPreferredSize() statements. The layout manager
will determine the preferred size of the component. Swing was designed to be used with
layout managers. Let the layout manager do its
job.

console = new
            JTextArea();

When
creating a JTextArea do something
like:

console = new JTextArea(5,
            30);

The will suggest
the size should be 5 rows and 30 columns. Now the layout manager can calculate a
preferred size based on this
information.

private BorderLayout
            BorderGlobalePan, BorderSecondPane, BorderManipPane,
            ...

Variable names
should NOT start with an upper case character. Most of your variable are correct, but
not all. Be
consistent!!!

frame.setSize(1024,
            600);

Don't hard code
a size. You don't know what the resolution of my computer is. Instead use the
pack() method and let the layout managers do their
job.
