A Pango::FontMap represents the set of fonts available for a particular rendering system.
This is an abstract base class with implementations being specific to particular rendering systems.

◆ create_context()
Glib::RefPtr<Context> Pango::FontMap::create_context |
( |
| ) |
|
Creates a PangoContext
connected to fontmap.
This is equivalent to [ctor Pango.Context.new] followed by [method Pango.Context.set_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 PangoContext
. For instance, the GTK toolkit has, among others, gtk_widget_get_pango_context(). Use those instead.
- Since pangomm 1.22:
- Returns
- The newly allocated
PangoContext
, which should be freed with Glib::object_unref().

◆ get_serial()
guint Pango::FontMap::get_serial |
( |
| ) |
const |
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 PangoFontMap
, like in PangoContext
.
- Since pangomm 1.32.4:
- Returns
- The current serial number of fontmap.
◆ get_type()
static GType Pango::FontMap::get_type |
( |
| ) |
|
|
static |
Get the GType for this class, for use with the underlying GObject type system.
◆ gobj() [1/2]
PangoFontMap* Pango::FontMap::gobj |
( |
| ) |
|
|
inline |
Provides access to the underlying C GObject.
◆ gobj() [2/2]
const PangoFontMap* Pango::FontMap::gobj |
( |
| ) |
const |
|
inline |
Provides access to the underlying C GObject.
◆ gobj_copy()
PangoFontMap* Pango::FontMap::gobj_copy |
( |
| ) |
|
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
◆ list_families()
List all families for the fontmap.
- Returns
- an array of pointers to Pango::FontFamily objects.
◆ load_font()
Load the font in the fontmap that is the closest match for desc.
- Parameters
-
context | The PangoContext the font will be used with. |
desc | A PangoFontDescription describing the font to load. |
- Returns
- The newly allocated
PangoFont
loaded, or nullptr
if no font matched.
◆ load_fontset()
Load a set of fonts in the fontmap that can be used to render a font matching desc.
- Parameters
-
context | The PangoContext the font will be used with. |
desc | A PangoFontDescription describing the font to load. |
language | A PangoLanguage the fonts will be used for. |
- Returns
- The newly allocated
PangoFontset
loaded, or nullptr
if no font matched.

bool |

related |
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.
