Detailed Description

Member Function Documentation

◆ describe()

FontDescription Pango::FontFace::describe ( ) const

Returns the family, style, variant, weight and stretch of a Pango::FontFace.

The size field of the resulting font description will be unset.

Returns: A Pango::FontDescription holding the description of the face.

◆ get_family() [1/2]

Glib::RefPtr< FontFamily > Pango::FontFace::get_family ( )

Gets the Pango::FontFamily that face belongs to.

Since pangomm 1.46:

Returns: The Pango::FontFamily.

◆ get_family() [2/2]

Glib::RefPtr< const FontFamily > Pango::FontFace::get_family ( ) const

Gets the Pango::FontFamily that face belongs to.

Since pangomm 1.46:

Returns: The Pango::FontFamily.

◆ get_name()

Glib::ustring Pango::FontFace::get_name ( ) const

Gets a name representing the style of this face.

Note that a font family may contain multiple faces with the same name (e.g. a variable and a non-variable face for the same style).

Returns: The face name for the face. This string is owned by the face object and must not be modified or freed.

◆ get_type()

static GType Pango::FontFace::get_type ( )

static

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

◆ gobj() [1/2]

PangoFontFace * Pango::FontFace::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const PangoFontFace * Pango::FontFace::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

PangoFontFace * Pango::FontFace::gobj_copy ( )

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

◆ is_synthesized()

bool Pango::FontFace::is_synthesized ( ) const

Returns whether a Pango::FontFace is synthesized.

This will be the case if the underlying font rendering engine creates this face from another face, by shearing, emboldening, lightening or modifying it in some other way.

Since pangomm 1.18:

Returns: Whether face is synthesized.

◆ list_sizes()

std::vector< int > Pango::FontFace::list_sizes ( ) const

List the available sizes for a font.

This is only applicable to bitmap fonts. For scalable fonts this returns an empty array. The sizes returned are in Pango units and are sorted in ascending order.

◆ operator=()

FontFace & Pango::FontFace::operator= ( FontFace && src )
