## 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 }
| The Pango::AttrType distinguishes between different types of attributes. More...
enum | Underline { UNDERLINE_NONE, UNDERLINE_SINGLE, UNDERLINE_DOUBLE, UNDERLINE_LOW, UNDERLINE_ERROR }
| The Pango::Underline enumeration is used to specify whether text should be underlined, and if so, the type of underlining. 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 | 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 }

## 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

typedef Glib::SListHandle< Glib::RefPtr<const LayoutLine>, LayoutLineTraits > Pango::SListHandle_ConstLayoutLine

## ◆ SListHandle_LayoutLine

typedef Glib::SListHandle< Glib::RefPtr<LayoutLine>, LayoutLineTraits > Pango::SListHandle_LayoutLine

## 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.
