ViewPortExtension Add-on | Vaadin

Add functionality to Vaadin Components to sense if they are in visible viewport or not

Have you considered that there is no point for UI components that are not in visible iviewport to fetch data from backend and update themselves. This is essential for heavy dashboard apps. Thus I wrote this handy extension, which can extend Vaadin component to have isInViewPort() status and ViewPortStatusChangedEvent to help optimizing large dashboards.
