Architecture

New Windowing API

public class Vaadin6App extends Application {

public void init() { setMainWindow(createWindow()); }

public Window getWindow(String name) { Window window = super.getWindow(name); if (window == null) { window = createWindow(); window.setName(name); addWindow(window); } return window; }

private Window createWindow() { Window window = new Window("Vaadin 6 Application"); window.addComponent(new TextField("What is your name")); window.addComponent(new Button("Do not push me")); return window; }

}

@Title("Vaadin 7 Application")public class Vaadin7uiUI extends UI {

public void init(VaadinRequest request) { addComponent(new TextField("What is your name")); addComponent(new Button("Do not push me")); }

Form form = new Form();form.setItemDataSource( new BeanItem<Employee>(employee));

form.setFormFieldFactory(new FormFieldFactory() {

GridLayout form = new GridLayout(2,2) {

TextField firstName = new TextField("First name"); TextField lastName = new TextField("Last name"); TextField salary = new TextField("Salary"); DateField birthDate = new DateField("Birth date");

{ birthDate.setResolution(Resolution.DAY); setSpacing(true); addComponent(firstName); addComponent(lastName); addComponent(birthDate); addComponent(salary); } };

BeanFieldGroup<Employee> fieldGroup = new BeanFieldGroup<Employee>(Employee.class); fieldGroup.bindMemberFields(form); fieldGroup.setItemDataSource(new BeanItem<Employee>(employee));

Demo

public interface ButtonRpc extends ServerRpc { public void click(MouseEventDetails details);}

private ButtonRpc rpc = RpcProxy.create(ButtonRpc.class, this);

public void onClick(ClickEvent event) { rpc.click( new MouseEventDetails(event));}

JavaScriptAdd-ons

getPage().getJavaScript().addCallback("myCallback", new JavaScriptCallback() { public void call(JSONArray arguments) throws JSONException { // Do something with the arguments } });

Publish API from Java

window.myCallback('foo', 100);

Use from JavaScript

window.com_example_MyWidget = function() { var element = $(this.getWidgetElement());

// Draw a plot for any server-side (plot data) state change this.onStateChange = function() { $.plot(element, this.getState().series, {grid: {clickable: true}}); }

// Communicate local events back to server-side component element.bind('plotclick', function(event, point, item) { if (item) {

var onPlotClick = this.getCallback("plotClick"); onPlotClick(item.seriesIndex, item.dataIndex); } });}

Widget implementation in JavaScript

public class MyWidget extends AbstractJavaScriptComponent {

public MyWidget() { registerCallback("plotClick", new JavaScriptCallback() { public void call(JSONArray arguments) throws JSONException { // Do something with the event } }); }

public static class MyWidgetState extends ComponentState { public List<List<List<Double>>> plotSeriesData = new ArrayList<List<List<Double>>>(); // getters & setters }

}
