## 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
}
| 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...

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

## Typedef Documentation

typedef PangoGlyph Pango::Glyph

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

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.

typedef PangoGlyphUnit Pango::GlyphUnit

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

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

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.

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

typedef PangoLogAttr Pango::LogAttr

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

typedef PangoMatrix Pango::Matrix

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

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

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

## 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.
