Hi,

Hmmmm I don't tryed it. Ok. Then my 2nd solution. Instead of using a
Vector use a DefaultListModel. It does the same like a Vector, but
better. You can add any Object to the model. If the Object has a
toString() method, this String will be shown in the List. You use
yourList.setModel(yourModel) to add the data. Later simply use
model.add(yourObject);.
To remove all use model.removeAllElements();
But this will crash if no elements are in the model. Test this with
model.isEmpty(); And read the documentation about DefaultListModel. It's
very useful. ;-) Much success with your list....
Michael
