if (c == removeCommand){
int index =
list.getSelectedIndex();
if (index != -1){
list.delete(index);
} else {
// no item selected
}
}
if (c == okCommand){
int index =
list.getSelectedIndex();
if (index != -1){
list.insert(index,
textbox.getString(), null);
} else {
// list might be empty
list.append(textbox.getString(),
null);
}
display.setCurrent(list);
