Graphics -Quick Start

Graphics -Quick StartThe Graphics package provides Symbian devices with a means of visual -communication. It is responsible for providing a system-wide interface with -the physical display(s) and handles input events from physical input devices -such as keypads and touch screens. -

There are two variants of the graphics architecture in Symbian^3. These -are referred to as ScreenPlay (sometimes -also called the New Graphics Architecture or NGA) and the non-ScreenPlay -variant (sometimes called the non-NGA variant). The Graphics guide -documentation covers both variants. When the documentation applies to only -one variant, it is clearly stated at the top of the page.

System Model

The -following diagram shows the Graphics package within the Symbian^3 System Model. -The System Model is a high-level overview of the Symbian architecture. The -components are grouped to show their relationships to each other. Within the -Graphics package, components are grouped into collections, which are shown -as white boxes in the diagram. The Graphics documentation is organized according -to the System Model structure.

Although the System Model provides a -useful way of grouping the large number of components that make up the Graphics -package, it does not completely reflect the architectural relationships between -the components.

- The Graphics package in the Symbian Foundation System -Model - -

This documentation -only covers collections and components that are relevant to application developers.

Technologies

For information on the -two architectures, see The -ScreenPlay Architecture and The -Non-ScreenPlay Architecture.
The graphics architecture -enables device creators to take advantage of graphics processing hardware -when it is available, and to use software implementations when it is not. -For more information, see Graphics -Hardware Acceleration.
Symbian provides support -for a number of APIs defined and administered by the Khronos group. These -enable the authoring and playback of dynamic media on a wide variety of platforms -and devices. For more information, see Khronos -API Support .
Application developers -use the Window Server client-side library to control windows and respond to -key and pointer events in their applications. For more information, see Window Server Client-Side -Library.
