MAnimationObserver Class Reference

class MAnimationObserver

Interface used by an animation to report events to the client application.

An animation can inform the client application of particular events through this mechanism. Only errors are reported in this way in v9.1, but more events may be added in future.

Use of this interface by the client application is optional.

Member Enumerations Documentation

Enum TEvent

Represents generic events which can be sent to the observer.

Enumerators

EDataProviderError	Indicates that an error has occurred in the data provider. For events of this type, aData is a pointer to a TInt error code.
EAnimationInitialized = 0x01	Indicates that the animator initialised (and therefore knows it's size)
EReserved = 0xFFFF	Any user defined animations introducing new events should use values greater than EReserved
