Does anyone know how to get rid of the little generic window icon in the
title bar of Dialogs? My application has an icon and I use
Frame.setIconImage() to set the same icon in the title bar of all my Frames
so I know how to set a window icon and that works fine. The problem is
Dialogs do not have a setIconImage() method, yet they have a generic icon.

Strangely enough the JVM's from Sun and IBM do not show this generic icon in
Dialogs (or any icon at all for that matter), but J# created Dialogs do, and
so do the Dialogs created under the Microsoft VM from the J++ days. So
maybe there is a way to set this icon that is specific to the Microsoft VM
(and J#)? Any help would be appreciated.

Please use a "FixedToolWindow" or "SizableToolWindow".

You will find this under the "FormBorderStyle" in the properties window in
the design view.

If you want to set this property with the API:

this.set_FormBorderStyle(System.Windows.Forms.FormBorderStyle.FixedToolWindo
w);

My problem is with a java.awt.Dialog. Sorry, I should have been more
specific. I assume you are talking about a System.Window derived object
here. I see no such property under any java.awt derived objects.

Sorry , I didn't read you question good enough, and sorry for the late
response (I'm packing all my things, beacuse I'm moving).

I get the small icon on a Sun Java 1.4.2 java.awt.Dialog dialog on WinXP Pro
too.
Do you have a small sample that can show us your scenario.

Sorry, there was one more piece of info. When you construct the dialog you
need to add two lines to make it modal and fixed size:

dialog.setModal(true);
dialog.setResizable(false);

Doing this make the icon go away on the Sun VM but it remains on the MS VM
(or J#). If I want a modeless dialog I use Frame which has a setIconImage()
method, so I have a workaround for the modeless case.

Here is the complete code:

import java.awt.Dialog;
import java.awt.FlowLayout;
import java.awt.Frame;
import java.awt.Label;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class DialogTest {

public static void main(String args[]) {
Dialog dialog = new Dialog(new Frame(), "Applet Frame");
dialog.setLocation(50, 50);
dialog.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});

dialog.setLayout(new FlowLayout(FlowLayout.CENTER, 0, 0));
dialog.add(new Label("Hello World"));
dialog.setModal(true);
dialog.setResizable(false);

dialog.pack();
dialog.setVisible(true);
}
}

Thank,

Mike
