Question

I’m using Netbeans to create a JList and an event listener.
I want to retrieve the object the user selected, when it’s selected.
So far I’ve got this:

private void listKurserValueChanged(javax.swing.event.ListSelectionEvent evt) {
    System.out.println("" + ((listKurser)evt.getSource()));
}

However, I’m getting “cannot find symbol” at listKurser, which is the JList.

What is wrong?

Answer 1

Try

private void listKurserValueChanged(javax.swing.event.ListSelectionEvent evt) {
    System.out.println("" + ((JList)evt.getSource()));

    JList changedList = (JList)evt.getSource();
    if (listKurser == changedList) {
        //listKurser was changed
    }
}
