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.

Member Function Documentation

Glib::RefPtr<FontFace> Pango::FontFamily::get_face ( const Glib::ustring & name = {} )

Gets the Pango::FontFace of family with the given name.

Since pangomm 1.46:

Parameters

name	The name of a face. If the name is `nullptr`, the family's default face (fontconfig calls it "Regular") will be returned.

Returns: The Pango::FontFace, or nullptr if no face with the given name exists.

Glib::RefPtr<const FontFace> Pango::FontFamily::get_face ( const Glib::ustring & name = {} ) const

Gets the Pango::FontFace of family with the given name.

Since pangomm 1.46:

Parameters

name	The name of a face. If the name is `nullptr`, the family's default face (fontconfig calls it "Regular") will be returned.

Returns: The Pango::FontFace, or nullptr if no face with the given name exists.

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.

bool Pango::FontFamily::is_variable ( ) const

A variable font is a font which has axes that can be modified to produce different faces.

Since pangomm 1.44:

Returns: true if the family is variable.

std::vector<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`
	)

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.
