A web engine configured for an ITF (IPTV Terminal Function), such as a STB (set-top-box), includes an application framework that enables display of applications. The application framework includes a memory for storing at least two applications, wherein the applications are arranged in a hierarchical tree structure in relation to each other. The application framework further includes an application manager. The application manager includes a receiving unit for receiving the event, e.g. a key press, and a controller for controlling the dispatching. The controller may include an event wrapper for wrapping and unwrapping the event and a dispatcher for transferring the wrapped event down through the application tree. For each application node including the root node, the application manager is configured to determine if an event should be processed by the current application.
