More input components
It's time to continue with our trip. Vaadin has several built-in input components (or fields as they implement directly or indirectly the Field interface). All these components extend from AbstractField or AbstractSelect. Let's take a look at some of them.
Text area
TextArea is quite similar to TextField. The difference is that the user can enter multiline texts. Take a look at this sample application:
public class TextareaUI extends UI implements ValueChangeListener {
@Override
protected void init(VaadinRequest request) {
// our TextArea component
TextArea textArea = new TextArea(
"Enter some multi-lined text and press TAB:");
textArea.addValueChangeListener(this);
textArea.setImmediate(true);
VerticalLayout layout = new VerticalLayout();
layout.addComponent(textArea);
setContent(layout);
}
@Override
public void valueChange(ValueChangeEvent event) {
String userText = event.getProperty().getValue()
