Examples of com.vaadin.navigator.Navigator

com.vaadin.navigator.Navigator
A navigator utility that allows switching of views in a part of an application.
The view switching can be based e.g. on URI fragments containing the view name and parameters to the view. There are two types of parameters for views: an optional parameter string that is included in the fragment (may be bookmarkable).
Views can be explicitly registered or dynamically generated and listening to view changes is possible.
Note that {@link Navigator} is not a component itself but comes with{@link SimpleViewDisplay} which is a component that displays the selectedview as its contents. @author Vaadin Ltd @since 7.0
