    Default How to close all tabs in JTabbedPane?

    Hi, I'm making a small chat program. I'm having problem with JTabbedPane, I want to remove all tabs in the JTabbedPane when the chat window closed(setvisible=false).
    Then if the user click another user name it'll launch again the chat window(setvisible=true).

    I'm having problem with the code so I use the setvisible method instead of making new chat window JFrame.

    The problem is when I can't remove all the tabs.
    this.removeAll()

    I got this error

    Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1

    Is the JTabbedPane doesn't allow empty tab state? When I make the JTabbedPane first time, it doesn't have tab right?

    Hope someone can help me,
    thanks

    Looking at the stack trace I don't see a call to the removeAll method. Are you sure that is where the error is happening?

    I put the remove function in this clearTab function
    	public void clearTab()
    	{
    		int i;
     
    		//for (i = 0; i < this.getTabCount(); i++)
    		//this.remove(i);	
     
    		this.removeAll();
    	}

    I tried to remove by iteration too but it's error like that if I remove all the tab..

    I just wrote a small test program and used removeAll() with no problem.
    I must be something else causes the error.

    Can you make and post here a small program to demo the problem?

    I don't use my customized tab, just use normal JTabbedPane

    public class Main
    {	
    	public Main(){
    	}
     
    	public static void main(String[] args)
    	{
    		final Tampilan tpl = new Tampilan();
     
            javax.swing.SwingUtilities.invokeLater(new Runnable() {
                public void run() {
                    tpl.showLogin();
                }
            });
     
    	}

    Tampilan is too long, in short it just make the buddy list with JTree in it, it then call a function to make the message box

    	public void createMessageBox()
    	{	
    		messageBox = new MessageBox();
    	}

    the messagebox class I created is like this, I removed the code for decorating the box

    public class MessageBox extends JFrame
    {
    	private static final long serialVersionUID = 1L;
    	JTabbedPane tabChat;
    	JFrame openerFrame;
     
    	public MessageBox()
    	{
    		super();
    		this.setSize(450, 350);
    		this.setResizable(true);
    		this.setLocationRelativeTo(null);
    		this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
     
    		tabChat = new JTabbedPane();
    		tabChat.addChangeListener(new ChangeListener() { 
    			// This method is called whenever the selected tab changes
    			public void stateChanged(ChangeEvent evt) { 
    				JTabbedPane pane = (JTabbedPane)evt.getSource(); 
     
    				// Get current tab 
    				int sel = pane.getSelectedIndex(); 
    				setJudul(pane.getTitleAt(sel));
    		} });
    		this.add(tabChat);
    	}
     
    	public void setJudul(String judul)
    	{
    		this.setTitle(judul);
    	}
     
    	public void closeChat()
    	{
    		this.setVisible(false);
    		tabChat.removeAll();
    	}
     
    	public void openChat(String namaUserLawan)
    	{	
    		tabChat.add(namaUserLawan, new javax.swing.JLabel(""));
    		this.setVisible(true);
    	}
    }

    Btw because of testing the code I found out that removing the listener solves the problem
    tabChat.addChangeListener

    Is there something I can do to fix this?

    Thanks

    I fixed my problem by just adding this

    				if (sel > 0)
    				setJudul(pane.getTitleAt(sel))


    Thanks a lot

    Look at this part of the error message:
    Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1
    at java.util.Vector.elementAt(Vector.java:430)
    at javax.swing.JTabbedPane.getTitleAt(JTabbedPane.jav a:1091)
    at epistle.MessageBox$2.stateChanged(MessageBox.java: 79)
    It says that the listener at line 79 did a getTitleAt() with -1.
    Add code to test the value of the selected index.


    BTW 0 is a valid index.
