Getting selected element from ListView

Question

I modify a ListView with the results from a database search in order to use that selection to make another DB request later on.

I want to get the field value of that ListView. What method can I use for that?

I just thought I can also add an event to the onclick and keep it on an attribute for the controller. Is that acceptable too?

Say with list view like this:

ListView<String> listView =new ListView<String>();

Getting selected element from ListView:

listView.getSelectionModel().getSelectedItem();

Tracking (Listening) the changes in list view selection:

listView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<String>() {
    @Override
    public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
        System.out.println("ListView selection changed from oldValue = " 
                + oldValue + " to newValue = " + newValue);
    }
});
