MDI Application - internal frame in seperate class
Hello everybody,
Before asking the question I want to say something. I am working in .NET since last three years. But now I want to migrate to Java , the main reason is platform independence. I have done a lot of projects in windows forms but started Swing this week only. This is my first question in any Java community, I am looking for good response.
Now I come to my question.
I am working on a MDI application swing using Netbeans 5.5.1. I am able to make a MDI app by using JDesktopPane and Internal frames but the problem is that I have to put all the code in one class(file) only. I want something like in windows form i.e. one file MDI.java and seperate files internal1.java, internal2.java etc so that I can display these internal frames using a Menu in MDI.java. I have searched a lot but could not find any solution so far.
Is there any solution? Kindly help.
P.S. - If you feel that I am not able to put the problem in good way feel free to ask further. As I have said I am new to Java, it will take time to understand things.

Where I've put the call to 'new JInternalFrame()' in the actionPerformed() method, you can put in a call to instantiate your own subclass of JInternalFrame (your subclass may be defined wherever).
Note JDesktopPane doesn't give you the nice stuff, like automatically positioning the internal frames, or a 'Windows' menu listing all the frames. You might find this link handy if you want that stuff:

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
public class JInternalFrameExample extends JFrame implements ActionListener {
private JDesktopPane desktop;
private int counter = 1;
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new JInternalFrameExample();
}
});
}
public JInternalFrameExample() {
setDefaultCloseOperation(EXIT_ON_CLOSE);
desktop = new JDesktopPane();
Container content = getContentPane();
JButton btnAdd = new JButton("Add Internal Frame");
btnAdd.addActionListener(this);
JMenuBar menu = new JMenuBar();
menu.add(btnAdd);
setJMenuBar(menu);
content.setLayout(new BorderLayout());
content.add(desktop, BorderLayout.CENTER);
Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
setSize((int) (screen.getWidth() * 0.75), (int) (screen.getHeight() * 0.75));
setVisible(true);
}
public void actionPerformed(ActionEvent e) {
JInternalFrame iFrame = new JInternalFrame("Internal Frame " + counter++, true, true, true, true);
iFrame.pack();
iFrame.setSize(new Dimension(300, 100));
iFrame.setVisible(true);
desktop.add(iFrame);
desktop.moveToFront(iFrame);
}
}
