Particular types of attributes derive this class. It holds the range in which the value in the type-specific part of the attribute applies. Attributed text is used in a number of places in pango. It is used as the input to the itemization process and also when creating a Pango::Layout. Constructor & Destructor Documentation Pango::Attribute::Attribute (   )    Constructs an invalid attribute. Pango::Attribute::Attribute ( const Attribute&    src )  Pango::Attribute::Attribute ( PangoAttribute*    castitem, bool    take_copy = true )  [explicit] Pango::Attribute::~Attribute (   )  Member Function Documentation AttrColor Pango::Attribute::create_attr_background ( guint16    red, guint16    green, guint16    blue )  [static]   Create a new background color attribute. Parameters: red  The red value (ranging from 0 to 65535). green  The green value (ranging from 0 to 65535). blue  The blue value (ranging from 0 to 65535). Returns: An attribute of type AttrColor. AttrString Pango::Attribute::create_attr_family ( const Glib::ustring&    family )  [static]   Create a new font family attribute. Parameters: family  The family or comma separated list of families. Returns: An attribute of type AttrString. AttrFontDesc Pango::Attribute::create_attr_font_desc ( const FontDescription&    desc )  [static]   Create a new font description attribute. This attribute allows setting family, style, weight, variant, stretch, and size simultaneously. Parameters: desc  The font description. Returns: An attribute of type AttrFontDesc. AttrColor Pango::Attribute::create_attr_foreground ( guint16    red, guint16    green, guint16    blue )  [static]   Create a new foreground color attribute. Parameters: red  The red value (ranging from 0 to 65535). green  The green value (ranging from 0 to 65535). blue  The blue value (ranging from 0 to 65535). Returns: An attribute of type AttrColor. AttrLanguage Pango::Attribute::create_attr_language ( const Language&    language )  [static]   Create a new language tag attribute. Parameters: language  The language tag. Returns: An attribute of type AttrLanguage. AttrInt Pango::Attribute::create_attr_rise ( int    rise )  [static]   Create a new baseline displacement attribute. Parameters: rise  The amount that the text should be displaced vertically, in 10'000ths of an em. Positive values displace the text upwards. Returns: An attribute of type AttrInt. AttrFloat Pango::Attribute::create_attr_scale ( double    scale_factor )  [static]   Create a new font size scale attribute. The base font for the affected text will have its size multiplied by scale_factor. Parameters: scale_factor  Factor to scale the font. Returns: An attribute of type AttrFloat. AttrShape Pango::Attribute::create_attr_shape ( const Rectangle&    ink_rect, const Rectangle&    logical_rect )  [static]   Create a new shape attribute. A shape is used to impose a particular ink and logical rect on the result of shaping a particular glyph. This might be used, for instance, for embedding a picture or a widget inside a PangoLayout. Parameters: ink_rect  Ink rectangle to assign to each character. logical_rect  Logical rectangle assign to each character. Returns: An attribute of type AttrShape. AttrInt Pango::Attribute::create_attr_size ( int    size )  [static]   Create a new font-size attribute. Parameters: size  The font size, in 1000ths of a point. Returns: An attribute of type AttrInt. AttrInt Pango::Attribute::create_attr_stretch ( Stretch    stretch )  [static]   Create a new font stretch attribute. Parameters: stretch  The stretch. Returns: An attribute of type AttrInt. AttrInt Pango::Attribute::create_attr_strikethrough ( bool    strikethrough )  [static]   Create a new font strike-through attribute. Parameters: strikethrough  True indicates the text should be struck-through. Returns: An attribute of type AttrInt. AttrInt Pango::Attribute::create_attr_style ( Style    style )  [static]   Create a new font slant style attribute. Parameters: style  The slant style. Returns: An attribute of type AttrInt. AttrInt Pango::Attribute::create_attr_underline ( Underline    underline )  [static]   Create a new underline-style object. Parameters: underline  The underline style. Returns: An attribute of type AttrInt. AttrInt Pango::Attribute::create_attr_variant ( Variant    variant )  [static]   Create a new font variant attribute (normal or small caps). Parameters: variant  The variant. Returns: An attribute of type AttrInt. AttrInt Pango::Attribute::create_attr_weight ( Weight    weight )  [static]   Create a new font weight attribute. Parameters: weight  The weight. Returns: An attribute of type AttrInt. bool Pango::Attribute::equal ( const Attribute&    attr2 )  const   Compare two attributes for equality. This compares only the actual value of the two attributes and not the ranges that the attributes apply to. Parameters: attr2  Another Pango::Attribute. Returns: true if the two attributes have the same value. unsigned int Pango::Attribute::get_end_index (   )  const   Gets the end index of the range. The character at this index is not included in the range. Returns: The end index of the range. unsigned int Pango::Attribute::get_start_index (   )  const   Gets the start index of the range. Returns: The start index of the range. AttrType Pango::Attribute::get_type (   )  const   Gets the type ID for this attribute. Returns: The type ID for this attribute or ATTR_INVALID if the attribute is invalid. PangoAttribute* const Pango::Attribute::gobj (   )  const [inline]   Reimplemented in Pango::AttrString, Pango::AttrLanguage, Pango::AttrColor, Pango::AttrInt, Pango::AttrFloat, Pango::AttrFontDesc, and Pango::AttrShape. PangoAttribute* Pango::Attribute::gobj (   )  [inline]   Reimplemented in Pango::AttrString, Pango::AttrLanguage, Pango::AttrColor, Pango::AttrInt, Pango::AttrFloat, Pango::AttrFontDesc, and Pango::AttrShape. Attribute& Pango::Attribute::operator= ( const Attribute&    src )  AttrType Pango::Attribute::register_type ( const Glib::ustring&    name )  [static]   Allocate a new attribute type ID. Parameters: name  An identifier for the type (currently unused). Returns: The new type ID. void Pango::Attribute::set_end_index ( const unsigned int&    value )    Sets the end index of the range. The character at this index is not included in the range. Parameters: end_index  The new end index. void Pango::Attribute::set_start_index ( const unsigned int&    value )    Sets the start index of the range. Parameters: start_index  The new start index.
