Undecorated Frame (with title bar)

Question

Is there a way to put a title bar accross my frame but remove the small buttons in the right side of the title bar? I can't really have "undecorated" frames since the user has to be able to resize and move the frame, but I don't want them to be able to see the "X" to close the window. I have disabled it by setting the default close operation to do nothing, but I am sure I will get complaints when they click on that and nothing happens (the way they close it is the same way they opened it -- via a checkboxmenuitem), so I think if they don't see the red x in the upper right corner they will just assume they have to use the checkboxmenuitem (and uncheck it) but if they see it they will want it to close it for them. Any ideas? I had thought of overriding the frame to catch the close operation but then I have to hook that frame to every checkboxmenuitem and it would get really hairy.

If I'm reading this right you have a JCheckbox with a listener so that when it 'unchecks',
there's some sort of code generated prior to the child window closing.
If so, can't you just add a windowlistener to the child frame, and in windowClosing 'uncheck' the checkbox
something like this
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class ParentWindow extends JFrame implements ItemListener
  JCheckBox chk = new JCheckBox("Open new window");
  ChildWindow cw;
  public ParentWindow()
    setLocation(300,200);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    JPanel jp = new JPanel();
    chk.addItemListener(this);
    jp.add(chk);
    getContentPane().add(jp);
    pack();
  public void itemStateChanged(ItemEvent ie)
    int state = ie.getStateChange();
    if(state == ItemEvent.SELECTED)
      cw = new ChildWindow(this);
    if(state == ItemEvent.DESELECTED)
      //other cose associated with uncheck event
      cw.dispose();
  public static void main(String args[]){new ParentWindow().setVisible(true);}
class ChildWindow extends JFrame
  ParentWindow parent;
  public ChildWindow(ParentWindow pw)
    parent = pw;
    setLocation(300,200);
    setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
    addWindowListener(new WindowAdapter(){
      public void windowClosing(WindowEvent e){
        parent.chk.setSelected(false);}}); //<-----------------
    JPanel jp = new JPanel();
    jp.add(new JLabel("Child Window"));
    getContentPane().add(jp);
    pack();
    setVisible(true);
}
