Enumerations

enum  AttrType {

  AttrType::INVALID,

  AttrType::LANGUAGE,

  AttrType::FAMILY,

  AttrType::STYLE,

  AttrType::WEIGHT,

  AttrType::VARIANT,

  AttrType::STRETCH,

  AttrType::SIZE,

  AttrType::FONT_DESC,

  AttrType::FOREGROUND,

  AttrType::BACKGROUND,

  AttrType::UNDERLINE,

  AttrType::STRIKETHROUGH,

  AttrType::RISE,

  AttrType::SHAPE,

  AttrType::SCALE_FACTOR,

  AttrType::FALLBACK,

  AttrType::LETTER_SPACING,

  AttrType::UNDERLINE_COLOR,

  AttrType::STRIKETHROUGH_COLOR,

  AttrType::ABSOLUTE_SIZE,

  AttrType::GRAVITY,

  AttrType::GRAVITY_HINT,

  AttrType::FONT_FEATURES,

  AttrType::FOREGROUND_ALPHA,

  AttrType::BACKGROUND_ALPHA,

  AttrType::ALLOW_BREAKS,

  AttrType::SHOW,

  AttrType::INSERT_HYPHENS,

  AttrType::OVERLINE,

  AttrType::OVERLINE_COLOR

}
 The Pango::AttrType distinguishes between different types of attributes. More...

 
enum  Underline {

  Underline::NONE,

  Underline::SINGLE,

  Underline::DOUBLE,

  Underline::LOW,

  Underline::ERROR,

  Underline::SINGLE_LINE,

  Underline::DOUBLE_LINE,

  Underline::ERROR_LINE

}
 The Pango::Underline enumeration is used to specify whether text should be underlined, and if so, the type of underlining. More...

 
enum  Overline {

  Overline::NONE,

  Overline::SINGLE

}
 The Pango::Overline enumeration is used to specify whether text should be overlined, and if so, the type of line. More...

 
enum  ShowFlags {

  ShowFlags::NONE = 0x0,

  ShowFlags::SPACES = 1 << 0,

  ShowFlags::LINE_BREAKS = 1 << 1,

  ShowFlags::IGNORABLES = 1 << 2

}
 These flags affect how Pango treats characters that are normally not visible in the output. More...

 
enum  Direction {

  Direction::RTL,

  Direction::TTB_LTR,

  Direction::TTB_RTL,

  Direction::WEAK_LTR,

  Direction::WEAK_RTL,

  Direction::NEUTRAL

}
 The Pango::Direction type represents a direction in the Unicode bidirectional algorithm; not every value in this enumeration makes sense for every usage of Pango::Direction; for example, the return value of pango_unichar_direction() and pango_find_base_dir() cannot be Pango::Direction::WEAK_LTR or Pango::Direction::WEAK_RTL, since every character is either neutral or has a strong direction; on the other hand Pango::Direction::NEUTRAL doesn't make sense to pass to pango_itemize_with_base_dir(). More...

 
enum  GravityHint {

  GravityHint::NATURAL,

  GravityHint::STRONG,

  GravityHint::LINE

}
 The Pango::GravityHint defines how horizontal scripts should behave in a vertical context. More...

  Stretch::NORMAL,

  Stretch::SEMI_EXPANDED,

  Stretch::EXPANDED,

  Stretch::EXTRA_EXPANDED,

  Stretch::ULTRA_EXPANDED

}
 An enumeration specifying the width of the font relative to other designs within a family. More...

 
enum  FontMask {

  FontMask::FAMILY = 1 << 0,

  FontMask::STYLE = 1 << 1,

  FontMask::VARIANT = 1 << 2,

  FontMask::WEIGHT = 1 << 3,

  FontMask::STRETCH = 1 << 4,

  FontMask::SIZE = 1 << 5,

  FontMask::GRAVITY = 1 << 6,

  FontMask::VARIATIONS = 1 << 7

}
 The bits in a Pango::FontMask correspond to fields in a Pango::FontDescription that have been set. More...

 
enum  Gravity {

  Gravity::SOUTH,

  Gravity::EAST,

  Gravity::NORTH,

  Gravity::WEST,

  Gravity::AUTO

}
 The Pango::Gravity type represents the orientation of glyphs in a segment of text. More...

A Pango::GlyphUnit is used to store dimensions within Pango.

Dimensions are stored in 1/64ths of a point.

Function Documentation

void Pango::init ( )

Initialize pangomm.

You may call this more than once. You do not need to call this if you are using Gtk::Main, because it calls it for you.
