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.

Code:

---

this.removeAll()

---

I got this error

Code:

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

I had something similar with the Java 1.4.2 version; I circumvented the problem by leaving at least one tab open (visible); my tabs are associated with text editors and my workaround was fine so I never looked at it again. We have to wait until Camickr reads this thread; he has the definitive answer, I'm sure about it; I even don't dare to report it as a bug because I'm not sure that what I did was correct or not.

kind regards,

The removeAll() method works fine for me using JDK6 on XP.

If you need more help then post a SSCCE that demonstrates the problem.

My code is too long to be pasted here.. I also use 4 class to make single window(caller, jframe, jpanel, jtabbedpane).
I have to post all the codes?

I'm using jdk1.6.0_16 in win xp, my IDE is eclipse

I also tried to remove the tab using iteration

Code:

---

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

---

It's just like josah say, I need to leave at least 1 tab to make it working.
I tried to add temporary tab so I can remove it at the adding tab process, but it still fails..

I did not ask for all the code. I asked for the SSCCE. The idea is for you to create a simple program to prove that the method does (or doesn't) work. If it works then you compare you demo code with your real code to see what is different. We are not here to debug your code for you.

Removed, what camickr said.

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

Code:

---

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

Code:

---

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

---

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

Code:

---

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

Code:

---

tabChat.addChangeListener

---

Is there something I can do to fix this?

Thanks

I got back to my old code and changed it: now all tabs can be removed and by golly it works. I don't remove them all at the same time, just each one, one by one individually. I could've sworn that it didn't work some time ago (that's why I left at least one tab in). After testing I changed it back again because in my case it doesn't really make sense to close/remove all tabs. For the record: I'm using Java 1.6 build 20.

kind regards,

Jos

I fixed my problem by just adding this

Code:

---

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

---

Thanks a lot :D
