AfterL(MSmilActive *, const TSmilTime &, TBool)

void	AfterL	(	MSmilActive *	iActive,
			const TSmilTime &	aDelay,
			TBool	aLazy = EFalse
		)	[pure virtual]

Invoke the ActivateL() method of iActive when delay aDelay has passed.

Parameters

MSmilActive * iActive
const TSmilTime & aDelay
TBool aLazy = EFalse

Alt()

TPtrC

Alt

(

)

const [pure virtual]

Alt tag

CancelActive(MSmilActive *)

void

CancelActive

(

MSmilActive *

aActive

)

[pure virtual]

Cancel a pending request

Parameters

MSmilActive * aActive

GetParam(const TDesC &)

TPtrC

GetParam

(

const TDesC &

aName

)

const [pure virtual]

Get media parameter, or empty TPtrC if not found

Parameters

const TDesC & aName

GetRectangle()

TRect

GetRectangle

(

)

const [pure virtual]

Returns the rectangle (region) where the media is supposed to be rendered on.

GetRegion()

MSmilRegion *

GetRegion

(

)

const [pure virtual]

Returns the region where this media is supposed to be rendered on. May be NULL.

MediaBegin()

TSmilTime

MediaBegin

(

)

const [pure virtual]

Returns begin time of media relative to presentation begin time.

MediaEnd()

TSmilTime

MediaEnd

(

)

const [pure virtual]

Returns end time of media relative to presentation begin time.

Presentation()

CSmilPresentation *

Presentation

(

)

const [pure virtual]

Redraw()

void

Redraw

(

)

[pure virtual]

Invoked by renderer to ask redrawing of area covered by the media. This should be invoked when (visual) media appears, there are changes to it, and when it is removed.

RendererAtEndL()

void

RendererAtEndL

(

)

[pure virtual]

Invoked by a MSmillMediaRenderer object when the associated media ends (end of the file or stream is reached). Renderer should also move to frozen state at this point (that is, to keep showing the last frame).

RendererDurationChangedL()

void

RendererDurationChangedL

(

)

[pure virtual]

Invoked by a MSmillMediaRenderer object when there is a change in (known) state of its intrinsic values. For example, duration of video clip is not typically known until it is at least partially decoded. This method should be invoked by the renderer when this information becomes available.

Src()

TPtrC

Src

(

)

const [pure virtual]

Media URL

Type()

TPtrC

Type

(

)

const [pure virtual]

Type attribute. Should be used to override the media type checking in the media factory, for example should cause factory to try opening the image as gif.
