View Server Tutorial

The UI Control Framework (CONE) provides CCoeAppUi that provides an interface to the View Server, which enables seamless switching between different views across various applications.

Introduction

The UI framework built on Cone/uikon can make a choice to use the View Server.

The view architecture allows applications to make and receive requests to show a particular view of their data. It allows applications to have integration between their user interfaces. This particularly allows the user to navigate through the UI on the basis of the task they are working on, rather than perceiving separate applications. For example, an application provides a view of a given Contact, any other application may display a contact using that view.

Views are UI controls that are derived from the MCoeView abstract view interface and display application data. Typically views are top-level window-owning controls. Each view is given a unique identifier of type TVwsViewId . TVwsViewId is a combination of the UID of the application and the UID of the view within the application. An application participating in the view switching must complete the steps given in the procedure section.
