Moving a glass pane

Hi All,

I am trying to create a modal JInternalFrame.
There are the following code in the constructor

JPanel glass = new JPanel();
glass.setOpaque(false);

setBounds(10, 10, 404, 313);
glass.setSize(400,400);
glass.setLocation(1,10)

glass.add(this);

glass.setLocation(1,10);
rootPane.setGlassPane(glass);
glass.setVisible(true);

I can see my modal window but it is always on the top and on the center
of the main Frame.
I was trying to set the size but it doesn't wark this way.
How can I locate, as I want, my JIF on this Glass layer?

root pane of what? JInternalFrame? JFrame?

Looks like you need to set glass pane for your JFrame, not for
JInternalFrame. Then you'll cover JFrame.

Ok this is what I've got:

>From the main JFrame class (MDI application that was created by

NetBeans 5.0) I call a JIF:

Update modal = new Update("Modal window", MainApp.this );

modal.setVisible(true);

try {
modal.setSelected(true);
} catch (java.beans.PropertyVetoException e1) {}

This is some code of the Update class:

public class Update extends javax.swing.JInternalFrame {

JPanel glass = new JPanel();
MouseInputAdapter adapter = new MouseInputAdapter(){};

public Update(String title, javax.swing.JFrame parent ) {

super ( title );
initComponents();

glass.setOpaque(false);
glass.addMouseListener(adapter);
glass.addMouseMotionListener(adapter);

glass.setBounds(20,20, 200, 200);
glass.add(this);

parent.getRootPane().setGlassPane( glass );

glass.setVisible(true);

System.out.println("InitGlass="+ glass.getLocation() + "
InitJIF="+ this.getLocation());
}

This Update class size and all other properties are set through the
InitComponents().

When the window appreas, the printing line got the following results:
InitGlass=java.awt.Point[x=20,y=20] InitJIF=java.awt.Point[x=0,y=0]

I have a button on this internal frame and when I press it without
moving the window, then I got:
BtnGlass=java.awt.Point[x=5,y=5] BtnJIF=java.awt.Point[x=88,y=5]

If I move the window and press the button, the Point values are
different, but the glass location remains x=5, y=5.

What could be wrong? Why I can't set the proper location for the first
time?

/*
* no needs to set bounds, glass pane
* should cover whole JFrame (without title bar area)
*/

> glass.setBounds(20,20, 200, 200);

/*
* If you need to show internal frame at specific
* location then:
*/

glass.setLayout(null);
this.setLocation(10, 10);

> glass.add(this);

parent.setGlassPane(glass);

> glass.setVisible(true);
