TFontStyle Class Reference

class TFontStyle

Encapsulates a font style.

The font style information is comprised of:

the posture of the font upright or italic

the stroke weight of the font normal or bold

the print position of the font normal, subscript or superscript

Note that the underline and strike-through attributes are not included in this class, but are set in the graphics context.

TFontStyle()

IMPORT_C

TFontStyle

(

)

IMPORT_C	TFontStyle	(	TFontPosture	aPost,
			TFontStrokeWeight	aStrWgt,
			TFontPrintPosition	aPrintPos
		)

Constructs a TFontStyle object with the specified attributes.

Parameters

TFontPosture aPost	The posture attribute.
TFontStrokeWeight aStrWgt	The stroke weight attribute.
TFontPrintPosition aPrintPos	The print position attribute.

Member Functions Documentation

BitmapType()

TGlyphBitmapType

BitmapType

(

)

const [inline]

Gets the anti-aliasing setting for the font, as set by SetBitmapType().

Effects()

IMPORT_C TUint32

Effects

(

)

const

Gets the font effects flags. TFontStyle::SetEffects()

ExternalizeL(RWriteStream &)

IMPORT_C void

ExternalizeL

(

RWriteStream &

aStream

)

const

Externalises the font style to a write stream.

The presence of this function means that the standard templated operator<<() (defined in s32strm.h) is available to externalise objects of this class.

leave: KErrNoMemory This function may leave, if the write action causes the stream's resources to be exhausted.

Parameters

RWriteStream & aStream

The stream to which the font style is to be externalised.

InternalizeL(RReadStream &)

IMPORT_C void

InternalizeL

(

RReadStream &

aStream

)

Internalises a font style from a read stream.

The presence of this function means that the standard templated operator>>() (defined in s32strm.h) is available to internalise objects of this class.

leave: KErrNoMemory If there is a problem reading from the stream. If internalisation causes an out of memory error.

Parameters

RReadStream & aStream

The stream from which the font style is to be internalised

IsEffectOn(FontEffect::TEffect)

IMPORT_C TBool

IsEffectOn

(

FontEffect::TEffect

aEffect

)

const

Checks if a font effect is on. TFontStyle::SetEffects()

Parameters

FontEffect::TEffect aEffect

The font effect to be checked.

Posture()

IMPORT_C TFontPosture

Posture

(

)

const

Gets the posture attribute.

PrintPosition()

IMPORT_C TFontPrintPosition

PrintPosition

(

)

const

Gets the print position attribute.

SetBitmapType(TGlyphBitmapType)

void

SetBitmapType

(

TGlyphBitmapType

aBitmapType

)

[inline]

Sets whether the font should be drawn using anti-aliasing. If set, this value overrides the default setting (set by CFbsTypefaceStore::SetDefaultBitmapType()) for this font.

Anti-aliasing can only be used for scalable fonts. There is currently no anti-aliasing support for bitmapped fonts.

Parameters

TGlyphBitmapType aBitmapType

Indicates whether or not this font should be drawn using anti-aliasing.

SetEffects(TUint32)

IMPORT_C void

SetEffects

(

TUint32

aEffects

)

Sets the font effects flags. TFontStyle::Effects()

Parameters

TUint32 aEffects

SetEffects(FontEffect::TEffect, TBool)

IMPORT_C void	SetEffects	(	FontEffect::TEffect	aEffect,
			TBool	aOn
		)

Sets a font effect to the given state. TFontStyle::IsEffectOn()

Parameters

FontEffect::TEffect aEffect	The font effect to be set.
TBool aOn	True represents on, otherwise off.

SetPosture(TFontPosture)

IMPORT_C void

SetPosture

(

TFontPosture

aPosture

)

Sets the posture attribute.

Parameters

TFontPosture aPosture

The posture to be set.

SetPrintPosition(TFontPrintPosition)

IMPORT_C void

SetPrintPosition

(

TFontPrintPosition

aPrintPosition

)

Sets the print position attribute.

Parameters

TFontPrintPosition aPrintPosition

The print position to be set.

SetStrokeWeight(TFontStrokeWeight)

IMPORT_C void

SetStrokeWeight

(

TFontStrokeWeight

aStrokeWeight

)

Sets the stroke weight attribute.

Parameters

TFontStrokeWeight aStrokeWeight

The stroke weight to be set.

StrokeWeight()

IMPORT_C TFontStrokeWeight

StrokeWeight

(

)

const

Gets the stroke weight attribute.

operator==(const TFontStyle &)

IMPORT_C TBool

operator==

(

const TFontStyle &

aFontStyle

)

const

Compares a font style for equality.

Parameters

const TFontStyle & aFontStyle

The font style to be compared with this font style.
