[RESOLVED] JFrame and JApplet Center on screen

[KGComputers]

Hi,

What's the method/code for centering a Japplet or JFrame on a monitor screen when loaded?

Thanks...

This should do it:

JFrame main = new JFrame();
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
...(set the size and all that)...
main.setLocation(((screenSize.width / 2) - (main.width / 2)), 
                  ((screenSize.height / 2) - (main.height / 2)) );

Applets are centered by HTML not by java code

I was answering that part, for the JFrame

[KGComputers]

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

public class CenterJFrame{
       public static void main(String[] a){

		JFrame main = new JFrame();
        
		main.setSize(new Dimension(400,500));
		Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
		//..(set the size and all that)...
		main.setLocation(((screenSize.width / 2) - (main.width / 2)),
                      ((screenSize.height / 2) - (main.height / 2)) );
        main.setVisible(true);
}
}

Hi, when experimenting your code I got an error message...Am I missing something? Is it the package to import?

Here's the error message..

D:\java programs\swing API\CenterJFrame.java:15: width is not public in java.awt.Component; cannot be accessed from outside package
main.setLocation(((screenSize.width / 2) - (main.width / 2)),
^
D:\java programs\swing API\CenterJFrame.java:16: height is not public in java.awt.Component; cannot be accessed from outside package
((screenSize.height / 2) - (main.height / 2)) );
^

Oh yeah, sorry about that. The main.width and main.height should be main.getWidth() and main.getHeight().

There was some othe way of doing this, but I honestly don't remember how. If I ever think of it, then I'll post it here.

Hi,

Glad if you can add some code...Thanks in advance...If you can post an html code on how to center a JApplet on screen, that would be fine also...
