I have a custom collection which implements ListModel
. When this collection changes, i need to notify the JList
. Typically you'd fireListDataChanged
, but this is not a method implemented by ListModel
.
How should I go about modifying my code to automatically update the JList
?
JList here:
this.selectedInterfacesJList.setModel(new TufinInterfaceCollection());
Collection here:
public class TufinInterfaceCollection extends AbstractCollection<TufinInterface> implements ListModel<String> {
ArrayList<TufinInterface> list=new ArrayList();
private final ArrayList listeners=new ArrayList();
@Override
public boolean remove(Object o) {
return list.remove(o); //To change body of generated methods, choose Tools | Templates.
}
@Override
public boolean add(TufinInterface e) {
return list.add(e); //To change body of generated methods, choose Tools | Templates.
}
public TufinInterface get(int i){
return list.get(i);
}
@Override
public Iterator<TufinInterface> iterator() {
return list.iterator();
}
@Override
public int size() {
return list.size();
}
@Override
public int getSize() {
return size();
}
@Override
public String getElementAt(int i) {
return get(i).toString();
}
@Override
public void addListDataListener(ListDataListener ll) {
this.listeners.add(ll);
}
@Override
public void removeListDataListener(ListDataListener ll) {
this.listeners.remove(ll);
}
}
