EnableAlpha(TBool)

TInt

EnableAlpha

(

TBool

aEnable = ETrue

)

[pure virtual]

Enables / disables alpha on composition target

Parameters

TBool aEnable = ETrue

SetExtent(const TRect &, TInt)

TInt	SetExtent	(	const TRect &	aRect,
			TInt	aScreen
		)	[pure virtual]

Defines extent of the composition target on a defined screen Does not affect on hit testing, keyboard focus etc. but is just additional information for composition

Parameters

const TRect & aRect
TInt aScreen

SetIsBackgroundAnim(TBool)

void

SetIsBackgroundAnim

(

TBool

ETrue

)

[pure virtual]

Makes this composition target system wide background surface

Parameters

TBool ETrue

SetOpacity(TReal32)

TInt

SetOpacity

(

TReal32

aOpacity

)

[pure virtual]

Set constant opacity (0..255) multiplier that will be applied to composition target <in practice, only 256 different shades supported>

Parameters

TReal32 aOpacity

SetRotation(TInt)

TInt

SetRotation

(

TInt

aRotationInDegrees

)

[pure virtual]

rotation of composition target <in practice, only 90 degree steps supported, value given will be rounded to closest rotation>

Parameters

TInt aRotationInDegrees

SetSourceRect(const TRect &)

TInt

SetSourceRect

(

const TRect &

aRect

)

[pure virtual]

Defines extent of the composition source rectangle

Parameters

const TRect & aRect
