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.
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);
}
}
