class Pango::Fontset

Overview

A Pango::Fontset represents a set of Pango::Font to use when rendering text.

A Pango::Fontset is the result of resolving a Pango::FontDescription against a particular Pango::Context. It has operations for finding the component font for a particular Unicode character, and for finding a composite set of metrics for the entire fontset.

Constructor Detail

def self.new #

Initialize a new Fontset.


Class Method Detail

def self.g_type : UInt64 #

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


Instance Method Detail

def font(wc : UInt32) : Pango::Font #

Returns the font in the fontset that contains the best glyph for a Unicode character.


def foreach(func : Pango::FontsetForeachFunc, data : Pointer(Void)?) : Nil #

Iterates through all the fonts in a fontset, calling @func for each one.

If @func returns true, that stops the iteration.


def metrics : Pango::FontMetrics #

Get overall metric information for the fonts in the fontset.
