Detailed Description

A transient container of character format attributes, including font-dependent and font-independent attributes.

The font-independent attributes are stored in a TFontPresentation object. Rich and global text objects store character formatting using character format layers (see class CCharFormatLayer). The TCharFormat class is used to store the relevant attribute values when setting or sensing a CCharFormatLayer. It is normally used in combination with a TCharFormatMask, to specify which attributes are relevant to the function concerned.

Member Attribute Documentation

iFontPresentation

TFontPresentation iFontPresentation

Font independent character format attributes.

iFontSpec

TFontSpec iFontSpec

Device independent font specification.

iLanguage

TInt32 iLanguage

Specifies the language of individual characters for proofing. Used for example when spell checking a document which contains text in more than one language, so that the program recognises the text as being in another language. Language is also a paragraph format attribute. If the language setting of a character is different from the language setting of the containing paragraph, the character's setting takes precedence.

Constructor & Destructor Documentation

TCharFormat ( )

IMPORT_CTCharFormat()

Allocates and constructs a TCharFormat object. The font-independent attributes are initialised with default values. The language is initialised to zero. The font (iFontSpec) is set to be proportional and serif and to have a height of 200 twips. The typeface name is not initialised.

TCharFormat ( const TDesC &, TInt )

IMPORT_CTCharFormat(const TDesC &aTypefaceName,
TIntaHeight
)

The C++ constructor is used to construct the TCharFormat object with a font (typeface name and font height). The font-independent attributes are initialised to default values; for details, see class TFontPresentation. The language is initialised to zero.

ParameterDescription
aTypefaceNameSpecifies the typeface name.
aHeightSpecifies the font height in twips.

Member Function Documentation

IsEqual ( const TCharFormat &, const TCharFormatMask & )

IMPORT_C TBoolIsEqual(const TCharFormat &aFormat,
const TCharFormatMask &aMask
)const

Compares selected attribute values for equality. Only the attributes specified in the mask are involved in the comparison.

ParameterDescription
aFormatContains the attribute values to compare.
aMaskBitmask specifying the attributes to compare.

Returns: ETrue if the two format containers have the same values for the attributes specified in the mask, EFalse if not.

IsEqual ( const TCharFormat & )

IMPORT_C TBoolIsEqual(const TCharFormat &aFormat)const

Compares all attribute values for equality.

ParameterDescription
aFormatContains the attribute values to compare.

Returns: ETrue if the two format containers have the same values for all attributes, EFalse if not.
