ValueLabel Add-on

Label that allows binding and value listeners in Vaadin 8.0

ValueLabel extends Label from Vaadin 8.0 and allows the developer to bind data to the component using Binder and to add value change listeners as well.

Sample code

		ValueLabel valueLabel = new ValueLabel(String.valueOf(valueInLabel));

		VerticalLayout layout = new VerticalLayout();
		layout.addComponent(valueLabel);
		setContent(layout);

		Binder<MyBean> binder = new Binder<>(MyBean.class);
		binder.bind(valueLabel, MyBean::getValue, MyBean::setValue);

		MyBean bean = new MyBean();
		bean.setValue("VALUE");

		binder.setBean(bean);

	private int value = 1;

	@Override
	protected void init(VaadinRequest request) {
		ValueLabel valueLabel = new ValueLabel(String.valueOf(value));
		valueLabel.addValueChangeListener(event -> Notification.show("Value Changed"));

		Button btnChangeValue = new Button("Change value", event -> valueLabel.setValue(String.valueOf(++value)));

		setContent(new VerticalLayout(valueLabel, btnChangeValue));
	}
