Hi fardeen,
I think u should use JWindow instead of JFrame which does not have any title bar.

Fardeen,

Since the window doesn't have a titlebar, there is no built in way to move it ( try it on a normal window... the only place you can grab a regular window to move it is the title bar... ) so you have to program in your own code to move the window... something like the following should suffice :

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
public class MovableWindow extends JWindow
            implements MouseMotionListener
{
    public MovableWindow()
    {
        addMouseMotionListener( this );
    }
 
    public void mouseDragged( MouseEvent event )
    {
        Rectangle size = getBounds();
        setBounds( event.getX() + size.x , event.getY() + size.y,
                   size.width, size.height );
    }
 
    public void mouseMoved( MouseEvent event )
    {
    }
 
    public static void main( String args[] )
    {
        MovableWindow mw = new MovableWindow();
        mw.setSize( 200, 200 );
        mw.setVisible( true );
    }
}

parul,

What OS are you running on? I am using Windows NT and the window doesn't disappear when I switch processes... it doesn't have a box on the taskbar ( since it doesn't have a titlebar it isn't a full-fledged window... ), but if you use alt-tab, you will be able to switch back to it...

Also... depending on the IDE, your class may be running inside the IDE process if you launch it from the IDE... try running your class from DOS to see if this is still a problem.

And, before asking if we can make the window always be on top... No... sorry... You can't make a system level modal window in java... only an application level modal window...

just when u create ur frame, on its init method, use this:

 this.setUndecorated(true);
