How to remove all items or a single item from a combo box in LWUIT ?
Is there any functions like removeall()
?
解决方案
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.
其他提示
