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.
|
noexcept |
|
overridenoexcept |
| Glib::RefPtr< Context > Pango::FontMap::create_context | ( | ) |
Creates a Pango::Context connected to fontmap.
This is equivalent to Pango::Context::new() followed by 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 Pango::Context. For instance, the GTK toolkit has, among others, gtk_widget_get_pango_context(). Use those instead.
Pango::Context, which should be freed with Glib::object_unref(). | Glib::RefPtr< FontFamily > Pango::FontMap::get_family | ( | const Glib::ustring & | name | ) |
| Glib::RefPtr< const FontFamily > Pango::FontMap::get_family | ( | const Glib::ustring & | name | ) | const |
| 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 Pango::FontMap, like in Pango::Context.
