Constructor & Destructor Documentation

TOpenFontFaceAttribBase()

TOpenFontFaceAttribBase

(

)

[inline]

Default C++ constructor.

This sets all attribute fields to zero. As for other T classes, there is no need to explicitly clean-up objects derived from this class.

Member Functions Documentation

Coverage()

const TUint *

Coverage

(

)

const [inline]

Gets a pointer to the sets of flags that indicate the font's Unicode coverage.

Each flag that is set represents a supported Unicode range. The mapping is defined in the TrueType documentation under the OS/2 table.

Note: Some useful subsets are defined as anonymous enumerated constants at the end of this class, see ELatinSet etc.

SetCoverage()

HasCJK()

TBool

HasCJK

(

)

const [inline]

Tests for support of Chinese ideographic characters.

These are used in Chinese, Japanese and Korean.

Note: A return value of ETrue implies that the font has a usable set of characters. It does not imply exhaustive coverage.

HasCyrillic()

TBool

HasCyrillic

(

)

const [inline]

Tests for support of Cyrillic characters.

Note: A return value of ETrue implies that the font has a usable set of characters. It does not imply exhaustive coverage.

HasGreek()

TBool

HasGreek

(

)

const [inline]

Tests for support of Greek characters.

Note: A return value of ETrue implies that the font has a usable set of characters. It does not imply exhaustive coverage.

HasHangul()

TBool

HasHangul

(

)

const [inline]

Tests for support of Korean Hangul characters.

Korean may also make use of Chinese characters.

Note: A return value of ETrue implies that the font has a usable set of characters. It does not imply exhaustive coverage.

HasCJK()

HasKana()

TBool

HasKana

(

)

const [inline]

Tests for support of Japanese syllabic characters.

This function tests for the presence of Hiragana and Katakana syllabic characters in the font, collectively called kana. These characters are not sufficient for the Japanese language, which also makes use of Chinese characters.

Note: A return value of ETrue implies that the font has a usable set of characters. It does not imply exhaustive coverage.

HasCJK()

HasLatin()

TBool

HasLatin

(

)

const [inline]

Tests for support of Latin characters.

Note: A return value of ETrue implies that the font has a usable set of characters. It does not imply exhaustive coverage.

IsBold()

TBool

IsBold

(

)

const [inline]

Tests if the typeface is inherently bold.

IsItalic()

TBool

IsItalic

(

)

const [inline]

Tests if the typeface is inherently italic.

IsMonoWidth()

TBool

IsMonoWidth

(

)

const [inline]

Tests if all the characters have the same width.

IsSerif()

TBool

IsSerif

(

)

const [inline]

Tests if the typeface has serifs.

IsSymbol()

TBool

IsSymbol

(

)

const [inline]

Tests if the typeface contains symbols only.

Name()

TPtrC

Name

(

)

const [inline]

Gets the typeface's name.

SetBold(TBool)

void

SetBold

(

TBool

aBold

)

[inline]

Sets the bold attribute.

Parameters

TBool aBold

The bold attribute takes this value: ETrue or EFalse.

SetCoverage(TUint, TUint, TUint, TUint)

void	SetCoverage	(	TUint	aCoverage0,
			TUint	aCoverage1 = 0,
			TUint	aCoverage2 = 0,
			TUint	aCoverage3 = 0
		)	[inline]

Sets the coverage flags.

The flags are held in four 32 bit integers. Each flag that is set represents a range of Unicode characters that is supported by the typeface: Latin, Greek, Cyrillic etc. The mapping is defined in the TrueType documentation under the OS/2 table.

Note: Some useful subsets are defined as anonymous enumerated constants at the end of this class, see ELatinSet etc.

Parameters

TUint aCoverage0	The first set of coverage flags (bits 0-31).
TUint aCoverage1 = 0	The second set of coverage flags (bits 32-63).
TUint aCoverage2 = 0	The third set of coverage flags (bits 64-95).
TUint aCoverage3 = 0	The fourth set of coverage flags (bits 96-127).

SetItalic(TBool)

void

SetItalic

(

TBool

aItalic

)

[inline]

Sets the italic attribute.

Parameters

TBool aItalic

The italic attribute takes this value ETrue or EFalse.

SetMonoWidth(TBool)

void

SetMonoWidth

(

TBool

aMonoWidth

)

[inline]

Sets the mono-width attribute.

Parameters

TBool aMonoWidth

The mono-width attribute takes this value: ETrue or EFalse.

SetName(const TDesC &)

void

SetName

(

const TDesC &

aName

)

[inline]

Sets the name attribute.

Parameters

const TDesC & aName

Descriptor containing typeface name.

SetSerif(TBool)

void

SetSerif

(

TBool

aSerif

)

[inline]

Sets the serif attribute.

Parameters

TBool aSerif

The serif attribute takes this value ETrue or EFalse.

operator==(const TOpenFontFaceAttribBase &)

TBool

operator==

(

const TOpenFontFaceAttribBase &

aAttrib

)

const [inline]

Equality operator.

Compares this and a specified set of font attributes, including the coverage and the typeface name.

In version 6.1, and earlier, the return value was TInt.

Parameters

const TOpenFontFaceAttribBase & aAttrib

The font attributes to compare. This is an object of TOpenFontFaceAttribBase or of a derived class.
