    Default Refresh jList

    Hey,

    so I'm stuck again, how to I refresh a jList? I have a textfield and an Add button. When I add text from the textfield to the database I would like to refresh the jList after the text is added to the database. How to I do it?

    Heres my jlist code:
    (Using netbeans swing design gui)
    Java Code:
    DefaultListModel model = new DefaultListModel();
    jList1 = new javax.swing.JList(model);
    
    jList1.setModel(new DefaultListModel() {
        DerbyCon der = new DerbyCon();
        ArrayList todo = der.getTodo();
        public int getSize() { return todo.size(); }
        public Object getElementAt(int i) { return todo.get(i); }
    });
    
    jList1.addMouseListener(new java.awt.event.MouseAdapter() {
        public void mouseClicked(java.awt.event.MouseEvent evt) {
            jList1MouseClicked(evt);
        }
    });
    
    jScrollPane2.setViewportView(jList1);

    Did you read the JList API? You will find a link to the Swing tutorial on "How to Use Lists" which has an example that does this.
