list issue

hi,
i have 3 buttons and a target jlist....each button runs its oen query to populate the list..so if i hit button 1 its populates the list with its items..

i'm using list.removeAll(); to clear the list and repopulate but it doesnt seem to work..so when i press button 1, it still jkeeps the items from button2 etc..

Mick Barry

JList does not have aremoveAll() method, what are calling removeAll() on exactly.
Sounds like you are not firing the appropriate event after removing

Mick Barry

if use DLM then use model.clear();

oh..i'm actually calling removeall() to clear and repopulate the items when the button is hit..so i need to use a datamodel?

Mick Barry

yes you need to remove the items from the model
another option would be to create a new model using setModel() or setListData()

this is what i've done..but it still doesnt clear the data

DefaultListModel modelList1 = new DefaultListModel();
final JList list1 = new JList(modelList1);
----

-- get data from database

--

ResultSet rs = pstmt.executeQuery();

modelList1.clear();

while (rs.next()) {

modelList1.add(0,rs.getString(1));
}
}
