Update text in a ListView

Question

I am trying update the text of an index in my ListView when text is typed into a TextField , but I don't know how to access the item to update the text. I know the index of the item, but I just cant seem to figure out how to update the text..

@FXML
ListView connections;

public ObservableList names = FXCollections.observableArrayList();

@FXML
public void onInputChanged(KeyEvent event){
    TextField fld = (TextField) event.getTarget();
    if(fld.getId().equals("txtName") && index > -1){

    }
}

Answer 1

names.set(index, fld.getText());

Answer 2

I think you need to use JavaFX Properties ie "SimpleStringProperty" to actually change the String in "names".

This link does explain it pretty accurately: https://gist.github.com/andytill/3116827

Hope it helps.
