Class CICLAnimationDataProvider

class CICLAnimationDataProvider : public CAnimationDataProvider, public MICLAnimationDataLoaderObserver;

Description

Data provider for frame based animations.

This data provider expects to be provided with a file which can be interpreted as an animation using the Image Conversion Library (ICL). An example would be an animated GIF. The default data type for this provider is "bitmap".

• Animation example

IMPORT_C CICLAnimationDataProvider();

Description

Default constructor.

IMPORT_C ~CICLAnimationDataProvider();

Description

Destructor.

It is normal for an animation to take ownership of a data provider, and hence responsibility for destroying it.

IMPORT_C void SetFileL(RFs &aFs, const TFileName &aFileName);

Description

Specifies the file to load the animation from.

This must be called before constructing an animation with this data provider. It may be called again for other files at any point during the lifespan of the animation, in which case current animation will be stopped.

Parameters

RFs &aFs A session with the file server const TFileName &aFileName The path to the image file to be loaded

virtual IMPORT_C TPtrC8 DataType();

Description

Called from the animation to obtain the type of data to expect.

Return value

TPtrC8 An 8 bit identifier string

virtual void StartL();

Description

Implmenets CAnimationDataProvider::StartL()

You do not need to call this function unless you are writing a new animation type.
