Using the fvwm window manager, in JDK 1.1.6
and 1.2Beta3 it appears that the border dimensions
are ignored when determining window locations.
As a result, placing a frame at 0,0 places the
window contained by the frame at 0,0 and leaves
the title border above the screen and inaccessable.

This bug is being submitted on behalf of a
large Sun customer by a Sun Systems Engineer.

import java.awt.*;
import java.awt.event.*;

class Main extends Frame {
    // The contructor creates a frame with a window size that gives
    // the desired interior size.
    Main() {
        super("Frame Example");
        // Calling addNotify() creates the peers; otherwise insets()
        // does not return the right values.
        addNotify();

        Insets insets = getInsets();
        setSize(insets.left + insets.right + 150,
                insets.top + insets.bottom + 150);

        // Add listener
        this.addMouseListener(new MouseEventHandler());

    }

    class MouseEventHandler extends MouseAdapter {
        public void mousePressed(MouseEvent evt) {
            // x, y are in interior coordinates
            // must be translated to screen coordinates.
            Rectangle bounds = getBounds();
//System.out.println("evt " + evt.getX() + " " + evt.getY());
            //System.out.println("bnd " + bounds.x + " " + bounds.y);
            int x = evt.getX() + bounds.x;
            int y = evt.getY() + bounds.y;

            // Set location of new frame
            Main m = new Main();
            //m.setLocation(X, Y);
m.setLocation(0,0);
            m.show();
        }
    }

    static public void main(String[] args) {
        (new Main()).show();
    }
}

AIM = AOL Instant Messenger. The Java version can be downloaded from
http://www.aol.com/aim/downloadjava.html If you don't have a
screen name yet, you need to start at http://www.aol.com/aim/ and get
one first. You are welcome to "im" me at screen name "AndyWick".
It would be great if we could get JavaSoft and/or SUN people using
AIM, especially since it *IS* now included on some *SUN* CD. :-)

Fvwm is a window manager, similiar to mwm, but it supports virtual screens
and lots more features. It is a very common window manager used
by programmers that I work with. You can get it at
ftp://ftp.hpc.uh.edu/pub/fvwm/version-2 I am using version 2.0.46

The bug itself is caused by the borders of the frames being ignored.
So this means the inside of the frame is considered 0,0 instead of
including the border. Say the width of the frame border is 10 pixels.
If I say place a frame at (0, 0), in reality the inside of the
frame would be (10,10) because the borders would be (0,0). In version
1.1.6 and 1.2beta3 they don't coun't the borders, so the borders show
up "offscreen". ie I say frame.setLocation(0,0) in reality does
setLocation(-10, -10).

Thanks,
Andy
