orig synopsis: "Window management fault with Forte under Linux (with KDE2)"

Name: skT45625 Date: 11/22/2000


Unavailable to me now. The environment is the Sun released JDK1.3 (first final
release) running on a Mandrake Linux 7.2 / x86 computer.



Steps: Run Forte using JDK1.3 under Linux on KDE2.

Window management is completely messed up. Windows do not appear where they
should, and are not sized as they should (e.g. the main toolbar sometimes
appears in the middle of the screen and is a tenth of the screen width, the
explorer window appears anywhere on the screen and is often zero-size).

When moving between virtual desktops, moving back to the desktop with Forte
doesn't cause all the windows to appear again. One must find them in
the "taskbar" and open them.

The "find" dialog box has a special problem in that after one item is found,
subsequent tries to open the dialog box fails; the box does not show up. One
must go to another virtual desktop, and come back before the box appears,
underneath another window.


Forte (and other Netbeans binaries) executes fine on Windows, but have this
problem on Linux.

Under KDE2 (linux ) and java 1.3 modal JDialogs are
created with unexpected sizes. This appears
to occur only on the second dialog created.
This problem does not appear to be present
on jdk.1.2. This problem does not appear to occur
on kde 1.x. It is present in jdk1.3.0_01.

In the sample code below the first dialog appears
correct, but the second dialog is smaller in size
even though it is created identically to the first.


import javax.swing.*;

import java.awt.event.*;

public class Test {
    public static void main( String [] arg ) {

        JFrame frame = new JFrame();
        frame.setSize( 600, 400 );
        frame.setLocation( 20, 20 );
        frame.setVisible( true );
        

        final JDialog d = new JDialog( frame, "test2", true );
        JButton b = new JButton( "exit");
        b.addActionListener( new ActionListener() {
                public void actionPerformed( ActionEvent e ) {
                    d.setVisible( false );
                }
            }
        );
                    
        d.getContentPane().add( b );
        d.setSize( 200, 300 );
        d.setLocation( 50, 50 );
        d.setVisible( true );

        final JDialog d2 = new JDialog( frame, "test2", true );
        JButton b2 = new JButton( "exit");
        b2.addActionListener( new ActionListener() {
                public void actionPerformed( ActionEvent e ) {
                    d2.setVisible( false );
                }
            }
        );
                    
        d2.getContentPane().add( b2 );
        d2.setSize( 200, 300 );
        d2.setLocation( 50, 50 );
        d2.setVisible( true );
        

    }

}

Attempting to run Netbeans Development Version under KDE 2.0, the first thing
that you'll notice is that the splash screen is reduced to a small dot on the
screen. Also, Netbeans (and Forte for Java 2.0 as well) has a very hard time
remembering the location of windows on the screen.

If you open a JOptionPane and then a JFrame, the size of the JFrame is wrong.

Window manager is KDE2.

Here is a sample program. The second frame should have a size of 320x200, but
instead it has something like 16x10. The sample works with IBM's JDK.

import javax.swing.*;
 
public class Test {
  public static void main( String[] asParam ) {
    JOptionPane jop = new JOptionPane(
      "Message", JOptionPane.INFORMATION_MESSAGE
    );
    JDialog jd = jop.createDialog( null, "Title" );
    jd.setModal( false );
 
    jd.show(); // comment out this line to get the second frame right
 
    JFrame jf = new JFrame( "Frame" );
    jf.setSize( 320, 200 );
    jf.setVisible( true );
  }
}

I cannot get a JDialog to redisplay after it has been hidden using. I have a
JFrame constructed and displayed, then popup a custom dialog. If the user
presses cancel, I hide the dialog by calling hide(). If I would like to show
the dialog again, I call show() and it doesn't display. It will show if I
minimize the dialog then maximize it again.

This only happens when I am using the KDE 2.X desktop. It works correctly on
KDE 1.X. So I am not sure if this is a KDE problem or JDK problem.

  To reproduce, run the code below on a system running Linux and KDE 2.X.
Choose File->show dialog from the menu. Press the cancel button in the center
of the dialog. Next, try to choose File->show dialog from the menu on the
JFrame again. The dialog will not display until you minimize the JFrame and
maximize it again.
