remove close button

[silversurfer2in]

Is there any way to remove the 'X' close button from JDialog
please help me i am stucked

You can't remove it but you can make it unresponsive by using:

dialog.setDefaultCloseOperation( JDialog.DO_NOTHING_ON_CLOSE );

i read on a thread that the way to do this is to remove the title bar and adding your own title bar
now the whole title bar can be removed by

setUndecorated(true)

but i dont know how to set my own title bar

i also tried the following code

public static void removeCloseButton(Component comp) {
    if (comp instanceof JMenu) {
      Component[] children = ((JMenu) comp).getMenuComponents();
      for (int i = 0; i < children.length; ++i)
        removeCloseButton(children[i]);
    }
    else if (comp instanceof AbstractButton) {
      Action action = ((AbstractButton) comp).getAction();
      String cmd = (action == null) ? "" : action.toString();
      if (cmd.contains("CloseAction")) {
        comp.getParent().remove(comp);
      }
    }
    else if (comp instanceof Container) {
      Component[] children = ((Container) comp).getComponents();
      for (int i = 0; i < children.length; ++i)
        removeCloseButton(children[i]);
    }
  }

but nothing worked out

to remove the X you firstly need to set java's L&F
JDialog.setDefaultLookAndFeelDecorated(true);

setting it 'before' the dialog is created.
then your removeCloseButton(..) works OK,
but java's L&F isn't overly popular

I tried it but its not working...
i am creating JDialog in a mouse listener event
my code goes like this

MouseListener mouseListener = new MouseAdapter() {
		
		 JDialog d = new JDialog(frame, "Human Resource");
		 
		   public void mouseEntered(MouseEvent me) {
			   JDialog.setDefaultLookAndFeelDecorated(true);
			   d.setSize(200,200);
			   

		        d.setLocation(me.getX(),me.getY());
		        d.setVisible(true);
		        removeCloseButton(d);

		   }

		   public void mouseExited(MouseEvent me) {
			   d.setVisible(false);
			
		   }
	 };
	 public static void removeCloseButton(Component comp) {
		    if (comp instanceof JMenu) {
		      Component[] children = ((JMenu) comp).getMenuComponents();
		      for (int i = 0; i < children.length; ++i)
		        removeCloseButton(children[i]);
		    }
		    else if (comp instanceof AbstractButton) {
		      Action action = ((AbstractButton) comp).getAction();
		      String cmd = (action == null) ? "" : action.toString();
		      if (cmd.contains("CloseAction")) {
		        comp.getParent().remove(comp);
		      }
		    }
		    else if (comp instanceof Container) {
		      Component[] children = ((Container) comp).getComponents();
		      for (int i = 0; i < children.length; ++i)
		        removeCloseButton(children[i]);
		    }
		  }

please check this and tell me

You didn't try it correctly.

noted previously:
"setting it 'before' the dialog is created."

in your code you create the dialog in the class,
then you set the default L&F in mouseEntered

what should be the look and feel... i have changed it to window feel

try {
    	    // Set L&F to window
    		UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");

        } 
        catch (UnsupportedLookAndFeelException e) {
           // handle exception
        }
        catch (ClassNotFoundException e) {
           // handle exception
        }
        catch (InstantiationException e) {
           // handle exception
        }
        catch (IllegalAccessException e) {
           // handle exception
        }

rest is same...and still its not working...please tell me...i will be very grateful

here's a working example

do NOT add any additional code to it, just copy/paste/compile/run,
and see that it removes the 'X', then play around with it.

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Testing
{
  public void buildGUI()
  {
    JDialog.setDefaultLookAndFeelDecorated(true);
    JDialog d = new JDialog();
    d.setModal(true);
    removeCloseButton(d);
    JPanel p = new JPanel(new GridBagLayout());
    JButton btn = new JButton("Exit");
    p.add(btn,new GridBagConstraints());
    d.getContentPane().add(p);
    d.setSize(400,300);
    d.setLocationRelativeTo(null);
    btn.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent ae){
        System.exit(0);
      }
    });
    d.setVisible(true);
  }

  public void removeCloseButton(Component comp) {
    if (comp instanceof JMenu) {
      Component[] children = ((JMenu) comp).getMenuComponents();
      for (int i = 0; i < children.length; ++i)
        removeCloseButton(children[i]);
    }
    else if (comp instanceof AbstractButton) {
      Action action = ((AbstractButton) comp).getAction();
      String cmd = (action == null) ? "" : action.toString();
      if (cmd.contains("CloseAction")) {
        comp.getParent().remove(comp);
      }
    }
    else if (comp instanceof Container) {
      Component[] children = ((Container) comp).getComponents();
      for (int i = 0; i < children.length; ++i)
        removeCloseButton(children[i]);
    }
  }
  public static void main(String[] args)
  {
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
      }
    });
  }
}
