## Detailed Description

A Pango::FontFamily is used to represent a family of related font faces.

The faces in a family share a common design, but differ in slant, weight, width and other aspects.

## Constructor & Destructor Documentation

Pango::FontFamily::FontFamily | ( | FontFamily&& | src | ) |
| noexcept

Pango::FontFamily::~FontFamily | ( |  | ) |
| override noexcept

## Member Function Documentation

Glib::ustring Pango::FontFamily::get_name | ( |  | ) | const

Gets the name of the family.

The name is unique among all fonts for the font backend and can be used in a Pango::FontDescription to specify that a face from this family is desired.

Returns
  The name of the family. This string is owned by the family object and must not be modified or freed.

static GType Pango::FontFamily::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

PangoFontFamily* Pango::FontFamily::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const PangoFontFamily* Pango::FontFamily::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

PangoFontFamily* Pango::FontFamily::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Pango::FontFamily::is_monospace | ( |  | ) | const

A monospace font is a font designed for text display where the the characters form a regular grid.

For Western languages this would mean that the advance width of all characters are the same, but this categorization also includes Asian fonts which include double-width characters: characters that occupy two grid cells. Glib::unichar_iswide() returns a result that indicates whether a character is typically double-width in a monospace font.

The best way to find out the grid-cell size is to call Pango::FontMetrics::get_approximate_digit_width(), since the results of Pango::FontMetrics::get_approximate_char_width() may be affected by double-width characters.

Since pangomm 1.4:

Returns
  `true` if the family is monospace.

Glib::ArrayHandle< Glib::RefPtr<FontFace> > Pango::FontFamily::list_faces | ( |  | ) | const

Lists the different font faces that make up family.

The faces in a family share a common design, but differ in slant, weight, width and other aspects.

Returns
  an array of pointers to Pango::FontFace objects.

FontFamily& Pango::FontFamily::operator= | ( | FontFamily&& | src | ) |
| noexcept

## Friends And Related Function Documentation

Glib::RefPtr< Pango::FontFamily > wrap | ( | PangoFontFamily * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
