jList

For the love of sweet jesus I have spent the last hour trying to figure out how to add strings to a jList from a button. How can I do this?

Lets say I want to add "A" "B" "C" "D" to jList1 which has already been drawn on the form. Thanks

Next time try taking a look at the JDoc before asking such a question

Code:

---

// Create a JList that displays strings from an array

 String[] data = {"one", "two", "three", "four"};
 JList myList = new JList(data);

 // Create a JList that displays the superclasses of JList.class, by
 // creating it with a Vector populated with this data

 Vector superClasses = new Vector();
 Class rootClass = javax.swing.JList.class;
 for(Class cls = rootClass; cls != null; cls = cls.getSuperclass()) {
    superClasses.addElement(cls);
 }
 JList myList = new JList(superClasses);
 
 // The automatically created model is stored in JList's "model"
 // property, which you can retrieve

 ListModel model = myList.getModel();
 for(int i = 0; i < model.getSize(); i++) {
    System.out.println(model.getElementAt(i));
 }

your code compiles but the only thing is I have already added the jList to the project before hand so dynamically creating a new jList doesnt do anything. I tried doing:

Code:

---

jList1 = jList;

---

(The already created jList on the form is named 'jList1')

but nothing appears in the jListbox. What am I doing wrong?
