class Pango::FontMap
- Pango::FontMap
- GObject::Object
- Reference
- Object
Overview
A Pango::FontMap
represents the set of fonts available for a
particular rendering system.
This is a virtual object with implementations being specific to particular rendering systems.
Defined in:
lib/gi-crystal/src/auto/pango-1.0/font_map.crConstructors
Class Method Summary
-
.g_type : UInt64
Returns the type id (GType) registered in GLib type system.
Instance Method Summary
-
#==(other : self)
Returns
true
if this reference is the same as other. -
#changed : Nil
Forces a change in the context, which will cause any
Pango::Context
using this fontmap to change. -
#create_context : Pango::Context
Creates a
Pango::Context
connected to fontmap. -
#family(name : String) : Pango::FontFamily
Gets a font family by name.
-
#hash(hasher)
See
Object#hash(hasher)
-
#list_families(families : Enumerable(Pango::FontFamily)) : Nil
List all families for a fontmap.
- #list_families(*families : Pango::FontFamily)
-
#load_font(context : Pango::Context, desc : Pango::FontDescription) : Pango::Font | Nil
Load the font in the fontmap that is the closest match for desc.
-
#load_fontset(context : Pango::Context, desc : Pango::FontDescription, language : Pango::Language) : Pango::Fontset | Nil
Load a set of fonts in the fontmap that can be used to render a font matching desc.
-
#serial : UInt32
Returns the current serial number of fontmap.

Constructor Detail
Class Method Detail
Returns the type id (GType) registered in GLib type system.
Instance Method Detail
Returns true
if this reference is the same as other. Invokes same?
.
Forces a change in the context, which will cause any Pango::Context
using this fontmap to change.
This function is only useful when implementing a new backend for Pango, something applications won't do. Backends should call this function if they have attached extra data to the context and such data is changed.
Creates a Pango::Context
connected to fontmap.
This is equivalent to Pango::Context.new
followed by
Pango::Context#font_map=
.
If you are using Pango as part of a higher-level system,
that system may have it's own way of create a Pango::Context
.
For instance, the GTK toolkit has, among others,
gtk_widget_get_pango_context(). Use those instead.
List all families for a fontmap.
Note that the returned families are not in any particular order.
Pango::FontMap
also implemented the Gio::ListModel
interface
for enumerating families.
Load the font in the fontmap that is the closest match for desc.
Load a set of fonts in the fontmap that can be used to render a font matching desc.
Returns the current serial number of fontmap.
The serial number is initialized to an small number larger than zero when a new fontmap is created and is increased whenever the fontmap is changed. It may wrap, but will never have the value 0. Since it can wrap, never compare it with "less than", always use "not equals".
The fontmap can only be changed using backend-specific API, like changing fontmap resolution.
This can be used to automatically detect changes to a Pango::FontMap
,
like in Pango::Context
.
