Constructor & Destructor Documentation

CAknsColorTableItemDef(const TAknsItemType, const TAknsItemID &)

CAknsColorTableItemDef	(	const TAknsItemType	aType,
		const TAknsItemID &	aID
	)	[protected]

C++ constructor for internal use. Constructs color item definition object with given ID. Color array must be set separately.

Parameters

const TAknsItemType aType	Type of the definition object. While this is always EAknsITColorTable for CAknsColorTableItemDef objects, derived classes may specify other values.
const TAknsItemID & aID	Item ID of the new item definition.

~CAknsColorTableItemDef()

~CAknsColorTableItemDef

(

)

[virtual]

Destructor. If the object owns a color array, it is destroyed.

Colors()

IMPORT_C const TAknsColorTableEntry *

Colors

(

)

const

Returns pointer to color values.

Since: 2.0

NewL(const TAknsItemID &, const TInt, const TAknsColorTableEntry *const)

IMPORT_C CAknsColorTableItemDef *	NewL	(	const TAknsItemID &	aID,
			const TInt	aNumberOfColors,
			const TAknsColorTableEntry *const	aColors
		)	[static]

Two-phased constructor, complete initialization. Constructs a new color table item definition object.

Exceptions:: If allocation fails, function leaves with a system-wide error code.

Parameters

const TAknsItemID & aID	Item ID of the new object.
const TInt aNumberOfColors	Number of colors available in aColors.
const TAknsColorTableEntry *const aColors	Pointer to the first color. Internal pointer is set to point to the same place as the given one. Ownership of the color array stays with the caller and it must ensure that its lifetime is appropriate.

NewL(const TAknsItemID &)

IMPORT_C CAknsColorTableItemDef *

NewL

(

const TAknsItemID &

aID

)

[static]

Two-phased constructor, partial initialization. Constructs a new color table item definition object. Colors must be set separately by using SetColorsL or SetColors.

Exceptions:: If allocation fails, function leaves with a system-wide error code.

Parameters

const TAknsItemID & aID

Item ID of the new object.

NumberOfColors()

IMPORT_C TInt

NumberOfColors

(

)

const

Returns the number of colors.

Since: 2.0

SetColors(const TInt, const TAknsColorTableEntry *const)

IMPORT_C void	SetColors	(	const TInt	aNumberOfColors,
			const TAknsColorTableEntry *const	aColors
		)

Sets the colors, ownership of the color array stays with the caller. If this object already owns a color array, it is destroyed.

Since: 2.0

Parameters

const TInt aNumberOfColors	Number of colors in aColors.
const TAknsColorTableEntry *const aColors	Pointer to the first color. The caller still owns the color array and must ensure that its lifetime is appropriate.

SetColorsL(const TInt, const TAknsColorTableEntry *const)

IMPORT_C void	SetColorsL	(	const TInt	aNumberOfColors,
			const TAknsColorTableEntry *const	aColors
		)

Sets the colors, content of the array is copied to an internal array. If this object already owns a color array, it is destroyed.

Since: 2.0

Exceptions:: If allocation fails, returns with an error code.

Parameters

const TInt aNumberOfColors	Number of colors in aColors.
const TAknsColorTableEntry *const aColors	Pointer to the first color.
