JDialog to appear in Windows Taskbar

[RVince]

I have an application whose only gui is to invoke a JDialog and
display it. On Windows machines, I need to have an the usual taskbar
button, typically at the bottom of the screen on Windows systems,
appear. It seems that simply invoking a modal JDialog wont put
anything into the Windows taskbar, and thus if a user puts another
Window in front of this JDialog -- they can even forget it's there!.

Does anyone know of a workaround to this? Thanks, R.Vince

As of 1.6 that is easy to do. Create a JDialog with the
DialogModalityType of TOOLKIT_MODAL.

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

public class test8 {
public static void main(String[] args) {
Runnable r = new Runnable() {
public void run() {
JDialog d = new JDialog(
(Frame)null,Dialog.ModalityType.TOOLKIT_MODAL);
d.setTitle("title");
d.setSize(300,200);
d.setVisible(true);
System.exit(0);
}
};
EventQueue.invokeLater(r);
}
}

Thanks Knute,

Unfortunately I have to be 1.4.2 compatible here. -R. Vince

Why would you want to use a compiler that in a very few months will be
obsolete?

Use a Frame/JFrame instead of a dialog.

showing taskbar button while JDialog opened

hi, i am new to this forum. so hope you all will forgive my mistakes if any....
Thank you in advance.

This is a answer for Rvince's question.
it is simple process though.

Just now before posting this reply I found the way. I was too searching internet for this answer. after all i found it my self.

i am doing an application for my personal use. it came up with the same issue when opening a dialog box, it hided the jframe. so i did a little bit of change to the code. and found workin better enough

this is the code which found erronic.
------------------------------------------------------

this.setVisible(false);
        
frmcompiler = new frmCompiler(this,true);
frmcompiler.setLocationByPlatform(true);
frmcompiler.setLocationRelativeTo(this);
frmcompiler.setVisible(true);

this.setVisible(true);

the statement

this.setVisible(true/false);

made it worst
it hided the jframe and the taskbar button vanished. so i made a little bit of change like the following

//this.setVisible(false);    
    
frmcompiler = new frmCompiler(this,true);
frmcompiler.setLocationByPlatform(true);
frmcompiler.setLocationRelativeTo(this);

this.setState(javax.swing.JFrame.ICONIFIED);

frmcompiler.setVisible(true);

//this.setVisible(true);
this.setState(javax.swing.JFrame.NORMAL);

see the difference? i just commented the visiblity statement and
used the setState function to the parent form. so i can iconify the parent form, and the taskbar button stayed alive...


hope this will help you....


oops forget to type.
frmCompiler is the JDialog window. and "this" denotes the parent form.

Mr. Rvince,

one more thing is i used Netbeans 7.1 and jdk 1.7. so i am not sure about how much it could work for you with java 1.4

Thank you
