Name: rmT116609 Date: 04/22/2004


FULL PRODUCT VERSION :
java version "1.5.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b32c)
Java HotSpot(TM) Client VM (build 1.5.0-beta-b32c, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Windows XP

A DESCRIPTION OF THE PROBLEM :
In Windows look and feel, when a JInternal Frame is maximized, and then minimized using the minimize button, the next JInternal Frame (if it is Maximizable) will be maximized.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Steps for reproducing this bug.
1) Run the following test code.
2) Maximize frame 2 using maximize button.
3) Minimize frame 2 using minimize button.
4) Frame 1 will now be maximized.



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


public class TestMdi
{
    public TestMdi()
    {
        JFrame frame = new JFrame("MDI Test Frame");

        JDesktopPane desktopPane = new JDesktopPane();
        desktopPane.setPreferredSize(new Dimension(400, 300));
        desktopPane.setBackground(Color.GREEN);
        frame.add(desktopPane, BorderLayout.CENTER);

        frame.pack();
        frame.setSize(1000,800);
        frame.setVisible(true);

        JInternalFrame iFrame1 = new JInternalFrame("Child 1 ", true, true, true, true);
        desktopPane.add(iFrame1);
        desktopPane.getDesktopManager().setBoundsForFrame(iFrame1, 0, 0, 200, 300);
        iFrame1.setVisible(true);

        JInternalFrame iFrame2 = new JInternalFrame("Child 2 ", true, true, true, true);
        desktopPane.add(iFrame2);
        desktopPane.getDesktopManager().setBoundsForFrame(iFrame2, 200, 0, 200, 300);
        iFrame2.setVisible(true);

    }

    public static void main(String[] args)
    {
        try
        {
            String className = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
            UIManager.setLookAndFeel(className);
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }

        TestMdi frame = new TestMdi();
    }
}


I believe this is due to changes made in the WindowsDesktopManager activateFrame method. The method works correctly when a frame is closed, but it should not maximize the next frame when a frame is minimized.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When a frame is maximized and then minimized, the next frame should NOT be maximized.
ACTUAL -
With two JInternal frames open and at their normal bounds. Frame 2 was maximized and then minimized. Frame 1 became maximized.

REPRODUCIBILITY :
This bug can be reproduced always.
