A user interface (UI) system where at a UI client engine is associated with an application, and a UI rendering engine is associated with the client engine. The UI client engine receives, from a UI client engine associated with an application, a UI component tree comprising: UI component nodes having associated predefined contextual rendering information, and a custom rendering element node having associated incomplete contextual rendering information; generating UI rendering instructions in accordance with the UI component tree by: for each UI component node, using the predefined contextual rendering information to generate UI component rendering instructions, for the custom rendering element node, retrieving custom rendering instructions generated by the application and generating incomplete rendering instructions based on the incomplete contextual rendering information; and combines the UI component rendering instructions, the incomplete rendering instructions and the retrieved custom rendering instructions; renders the UI in accordance with the generated UI rendering instructions.

Method of rendering a user interface

A user interface (UI) is presented in which a UI client engine is associated with an application, and a UI rendering engine is associated with the client engine. The UI rendering engine receives the scene graph and data items associated with elements of the scene graph, and processes a rendering thread to render a UI in accordance with the scene graph and the data items, independently of further input from the client UI engine.

The UI client engine processes a client thread to manage a scene graph. The UI rendering engine receives the scene graph and data items associated with elements of the scene graph, and processes a rendering thread to render a UI in accordance with the scene graph and the data items, independently of further input from the client UI engine.
