Vaadin Widgets

Vaadin comes with a number of Vaadin-specific widgets in addition to the GWT widgets, some of which you can use in pure client-side applications. The Vaadin widgets have somewhat different feature set from the GWT widgets and are foremost intended for integration with the server-side components, but some may prove useful for client-side applications as well.

Java

public class MyEntryPoint implements EntryPoint {
    @Override
    public void onModuleLoad() {
        // Add a Vaadin button
        VButton button = new VButton();
        button.setText("Click me!");
        button.addClickHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent event) {
                mywidget.setText("Clicked!");
            }
        });
        RootPanel.get().add(button);
    }
}
