Detailed Description

This is used to set a glyph name or glyph id for a glyph with no unicode value. The unicode value kTextChar_SpecialGlyph or kTextChar_NonRomanSpecial is used in the story to indicate that this attribute should be used for the glyph id. When this attribute is constructed glyph name is nil and GlyphID is 0. Normally you will only set either the glyph name or the glyph id.

Member Function Documentation

virtual ValueType ITextAttrSpecialGlyph::Get ( ) const

pure virtual

Gets the glyph name for the attribute. May be nil if only ID is set.

Returns

ValueType glyph name set for a attribute

virtual AlternateValueType ITextAttrSpecialGlyph::GetGlyphID ( ) const

pure virtual

Get glyph id for attribute.

Returns

AlternateValueType glyph id for attribute.

virtual void ITextAttrSpecialGlyph::Set ( ValueType  flag )

pure virtual

Set to glyph name. The name is used first to find a glyph in the fonts. If no glyph is found the value set by SetGlyphID will be used. Calling this does not reset glyph id. These names are usually obtained from IPMFont::GetGlyphName. Glyph names are prefferable to glyph ids because when switching fonts glyph ids may not represent the same glyph but glyph names are more likely to represent the same glyph.

Parameters

flag	glyph name to set

virtual void ITextAttrSpecialGlyph::SetGlyphID ( AlternateValueType  g )

pure virtual

Set glyph id for attribute. This will set glyph name to nil. A glyph id is only reliable across font changes if the 2 fonts have the same font registry and font ordering.

Parameters

g	glyph id to set for attribute
