## Enumerations
enum | AttrType { ATTR_INVALID , ATTR_LANGUAGE , ATTR_FAMILY , ATTR_STYLE , ATTR_WEIGHT , ATTR_VARIANT , ATTR_STRETCH , ATTR_SIZE , ATTR_FONT_DESC , ATTR_FOREGROUND , ATTR_BACKGROUND , ATTR_UNDERLINE , ATTR_STRIKETHROUGH , ATTR_RISE , ATTR_SHAPE , ATTR_SCALE , ATTR_FALLBACK , ATTR_LETTER_SPACING , ATTR_UNDERLINE_COLOR , ATTR_STRIKETHROUGH_COLOR , ATTR_ABSOLUTE_SIZE , ATTR_GRAVITY , ATTR_GRAVITY_HINT , ATTR_FONT_FEATURES , ATTR_FOREGROUND_ALPHA , ATTR_BACKGROUND_ALPHA , ATTR_ALLOW_BREAKS , ATTR_SHOW , ATTR_INSERT_HYPHENS , ATTR_OVERLINE , ATTR_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 { SHOW_NONE = 0x0 , SHOW_SPACES = 1 << 0 , SHOW_LINE_BREAKS = 1 << 1 , SHOW_IGNORABLES = 1 << 2 }
| These flags affect how Pango treats characters that are normally not visible in the output. More...
enum | Direction { DIRECTION_LTR , 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 { GRAVITY_HINT_NATURAL , GRAVITY_HINT_STRONG , GRAVITY_HINT_LINE }
| The Pango::GravityHint defines how horizontal scripts should behave in a vertical context. More...
enum | CoverageLevel { COVERAGE_NONE , COVERAGE_FALLBACK , COVERAGE_APPROXIMATE , COVERAGE_EXACT }
| Used to indicate how well a font can represent a particular Unicode character point for a particular script. More...
enum | Style { STYLE_NORMAL , STYLE_OBLIQUE , STYLE_ITALIC }
| An enumeration specifying the various slant styles possible for a font. More...
enum | Variant { VARIANT_NORMAL , VARIANT_SMALL_CAPS }
| An enumeration specifying capitalization variant of the font. More...
enum | Stretch { STRETCH_ULTRA_CONDENSED , STRETCH_EXTRA_CONDENSED , STRETCH_CONDENSED , STRETCH_SEMI_CONDENSED , 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 | Weight { WEIGHT_THIN = 100 , WEIGHT_ULTRALIGHT = 200 , WEIGHT_LIGHT = 300 , WEIGHT_SEMILIGHT = 350 , WEIGHT_BOOK = 380 , WEIGHT_NORMAL = 400 , WEIGHT_MEDIUM = 500 , WEIGHT_SEMIBOLD = 600 , WEIGHT_BOLD = 700 , WEIGHT_ULTRABOLD = 800 , WEIGHT_HEAVY = 900 , WEIGHT_ULTRAHEAVY = 1000 }
| An enumeration specifying the weight (boldness) of a font. More...
enum | FontMask { FONT_MASK_FAMILY = 1 << 0 , FONT_MASK_STYLE = 1 << 1 , FONT_MASK_VARIANT = 1 << 2 , FONT_MASK_WEIGHT = 1 << 3 , FONT_MASK_STRETCH = 1 << 4 , FONT_MASK_SIZE = 1 << 5 , FONT_MASK_GRAVITY = 1 << 6 , FONT_MASK_VARIATIONS = 1 << 7 }
| The bits in a Pango::FontMask correspond to fields in a Pango::FontDescription that have been set. More...

## Typedef Documentation

## ◆ Glyph

typedef PangoGlyph Pango::Glyph

A Pango::Glyph represents a single glyph in the output form of a string.

## ◆ GlyphItem

typedef LayoutRun Pango::GlyphItem

A Pango::GlyphItem is a pair of a Pango::Items and the glyphs resulting from shaping the text corresponding to an item.

As an example of the usage of Pango::GlyphItem, the results of shaping text with Pango::Layout is a list of Pango::LayoutLine, each of which contains a list of Pango::GlyphItem.

## ◆ GlyphUnit

typedef PangoGlyphUnit Pango::GlyphUnit

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

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

## ◆ GlyphVisAttr

typedef PangoGlyphVisAttr Pango::GlyphVisAttr

A Pango::GlyphVisAttr is used to communicate information between the shaping phase and the rendering phase.

It's contents are still evolving.

## ◆ ListHandle_Item

typedef Glib::ListHandle<Item, ItemTraits> Pango::ListHandle_Item

## ◆ LogAttr

typedef PangoLogAttr Pango::LogAttr

A Pango::LogAttr stores information about the attributes of a single character.

## ◆ Matrix

typedef PangoMatrix Pango::Matrix

## ◆ SListHandle_Attribute

typedef Glib::SListHandle<Attribute, AttributeTraits> Pango::SListHandle_Attribute

## ◆ SListHandle_ConstLayoutLine

## Function Documentation

## ◆ init()

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.
