How to remove all items or a single item from a combo box in LWUIT ?

Is there any functions like removeall() ?

해결책

Use getModel().removeItem(index) and remove the item's from ComboBox. See the sample code,

ComboBox c = new ComboBox(vector); // you can use ListModel or String[] instead of vector

// for remove single item in combobox
c.getModel().removeItem(index); // pass the removable index number

If you want to remove all item means set the empty ListModel on combobox.setModel(model) or pass the empty Vector on ComboBox constructor.
