Member Function Documentation
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, gdk_pango_context_get_for_screen(), and gtk_widget_get_pango_context(). Use those instead.
- Returns
- The newly allocated Pango::Context, which should be freed with Glib::object_unref().
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.
- Returns
- The current serial number of fontmap.

Provides access to the underlying C GObject.
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.
std::vector<Glib::RefPtr<FontFamily> > Pango::FontMap::list_families | ( | ) | const |
List all families for the fontmap.
- Returns
- an array of pointers to Pango::FontFamily objects.
Glib::RefPtr<Font> Pango::FontMap::load_font | ( | const Glib::RefPtr< Context >& | context, |
const FontDescription& | desc | ||
) | const |
Load the font in the fontmap that is the closest match for desc.
- Parameters
-
context The Pango::Context the font will be used with. desc A Pango::FontDescription describing the font to load.
- Returns
- The newly allocated Pango::Font loaded, or
nullptr
if no font matched.
Glib::RefPtr<Fontset> Pango::FontMap::load_fontset | ( | const Glib::RefPtr< Context >& | context, |
const FontDescription& | desc, | ||
const Language& | language | ||
) | const |
Load a set of fonts in the fontmap that can be used to render a font matching desc.
- Parameters
-
context The Pango::Context the font will be used with. desc A Pango::FontDescription describing the font to load. language A Pango::Language the fonts will be used for.
- Returns
- The newly allocated Pango::Fontset loaded, or
nullptr
if no font matched.

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.
