Examples of UI

com.eclipsesource.tabris.ui.UI

For a Tabris UI one {@link UI} object exists. This object will be passed in you {@link UIConfiguration}implementation to add pages and actions. Think about it as the glue between you pages and actions.

com.vaadin.ui.UI
The topmost component in any component hierarchy. There is one UI for every Vaadin instance in a browser window. A UI may either represent an entire browser window (or tab) or some part of a html page where a Vaadin application is embedded.
The UI is the server side entry point for various client side features that are not represented as components added to a layout, e.g notifications, sub windows, and executing javascript in the browser.

When a new UI instance is needed, typically because the user opens a URL in a browser window which points to e.g. {@link VaadinServlet}, all {@link UIProvider}s registered to the current {@link VaadinSession} arequeried for the UI class that should be used. The selection is by default based on the UI init parameter from web.xml.

After a UI has been created by the application, it is initialized using {@link #init(VaadinRequest)}. This method is intended to be overridden by the developer to add components to the user interface and initialize non-component functionality. The component hierarchy must be initialized by passing a {@link Component} with the main layout or other content of the viewto {@link #setContent(Component)} or to the constructor of the UI.
