Hide/remove maximize button on JFrame.

G'day everyone.

I have a JFrame which I wish to remove or completely hide the Maximize button (on top right hand corner) yet leave the Minimize and Close buttons still showing.

I've tried a few things such as setting resizable to false ( frame.setResizable(false); ) but that just seems to disable the button not hide it completely.

I have also tried using a JDialog instead of a JFrame but that seems to just show the close button, not the minimize.

Points to anyone who can show me the code to achieve what i want.

Cheers!

Think you'll need to handle painting the title bar yourself to achieve that.

Hi objects. I did suspect as much.

Seems like such a simple thing though.. have you stumbled upon any code which will help me?

Hi Javatm, I've just had a play with JInternalFrame and as you said it does remove the minimize button.

But the main window remains open when you click minimize and close... are you suggesting i catch the event and pass it over to the parent? also i can't seem to find where i get rid of the title bar from the parent frame. One more thing, i have a LAF and it renders internal frames quite ugly...

I still prefer Object's proposed method at this stage.. as to avoid the above complications. Just like someone to post some code on how to get that working.

Try this :

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

public class Word extends JWindow {

public Word()
{
super("Word Processor . . .");

JDesktopPane p1 = new JDesktopPane();
JInternalFrame f1 = new JInternalFrame("",false,true,false,true);

JTextArea txt1 = new JTextArea();
txt1.setSize(300,300);

f1.add(new JScrollPane(txt1));
f1.show();
p1.add(f1);

getContentPane().setLayout( new BorderLayout() );
getContentPane().add( p1, BorderLayout.CENTER);

setSize(500, 500);
show();
}

public static void main (String args[])
{
Word x = new Word();
x.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

Sorry I remebered that we are JWindow for us to remove the Titlebar
Its like this actually :

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

public class Word extends JWindow {

public Word()
{
JDesktopPane p1 = new JDesktopPane();
JInternalFrame f1 = new JInternalFrame("Sample . . .",false,true,false,true);

JTextArea txt1 = new JTextArea();
txt1.setSize(300,300);

f1.add(new JScrollPane(txt1));
f1.show();
p1.add(f1);

getContentPane().setLayout( new BorderLayout() );
getContentPane().add( p1, BorderLayout.CENTER);

setSize(500, 500);
show();
}

public static void main (String args[])
{
Word x = new Word();

x.addWindowListener(
new WindowAdapter() {
public void windowClosing( WindowEvent e )
{
System.exit( 0 );
}
}
);
}
}

If you want to close the entire program just click on the "x" mark on the
Internal Frame w/ this codes :

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

public class Word extends JWindow {

public Word()
{
JDesktopPane p1 = new JDesktopPane();
JInternalFrame f1 = new JInternalFrame("Sample . . .",false,true,false,true);

JTextArea txt1 = new JTextArea();
txt1.setSize(300,300);

f1.add(new JScrollPane(txt1));
f1.show();
p1.add(f1);

f1.setDefaultCloseOperation(JInternalFrame.EXIT_ON_CLOSE);

getContentPane().setLayout( new BorderLayout() );
getContentPane().add( p1, BorderLayout.CENTER);

setSize(500, 500);
show();
}

public static void main (String args[])
{
Word x = new Word();
}
}

As what Object said " Think you'll need to handle painting the title bar yourself ".

This is hard to do thats why I'm giving you a much easier way.
