class Pango::FontFamily


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

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

Constructor Detail

def #

Initialize a new FontFamily.

def*, item_type : UInt64? = nil, n_items : UInt32? = nil) #

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.

Instance Method Detail

def face(name : String?) : Pango::FontFace? #

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

def is_monospace : Bool #

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. g_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#approximate_digit_width, since the results of Pango::FontMetrics#approximate_char_width may be affected by double-width characters.

def is_variable : Bool #

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

Such axes are also known as variations; see Pango::FontDescription#variations= for more information.

def item_type : UInt64 #

def list_faces : Nil #

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.

Note that the returned faces are not in any particular order, and multiple faces may have the same name or characteristics.

Pango::FontFamily also implemented the Gio::ListModel interface for enumerating faces.

def n_items : UInt32 #

def name : String #

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.
