Class

PangoFontMap

Description [src]

abstract class Pango.FontMap : GObject.Object
  implements Gio.ListModel {
  /* No available fields */
}

A PangoFontMap represents the set of fonts available for a particular rendering system.

This is a virtual object with implementations being specific to particular rendering systems.

Instance methods

pango_font_map_changed

Forces a change in the context, which will cause any PangoContext using this fontmap to change.

since: 1.34

pango_font_map_create_context

Creates a PangoContext connected to fontmap.

since: 1.22

pango_font_map_get_family

Gets a font family by name.

since: 1.46

pango_font_map_get_serial

Returns the current serial number of fontmap.

since: 1.32.4

pango_font_map_list_families

List all families for a fontmap.

pango_font_map_load_font

Load the font in the fontmap that is the closest match for desc.

pango_font_map_load_fontset

Load a set of fonts in the fontmap that can be used to render a font matching desc.

pango_font_map_reload_font

Returns a new font that is like font, except that its size is multiplied by scale, its backend-dependent configuration (e.g. cairo font options) is replaced by the one in context, and its variations are replaced by variations.

since: 1.52

Please see GObject for a full list of methods.

Methods inherited from GListModel (5)
g_list_model_get_item

Get the item at position.

g_list_model_get_item_type

Gets the type of the items in list.

g_list_model_get_n_items

Gets the number of items in list.

g_list_model_get_object

Get the item at position.

g_list_model_items_changed

Emits the GListModel::items-changed signal on list.

Properties

Pango.FontMap:item-type

The type of items contained in this list.

Pango.FontMap:n-items

The number of items contained in this list.

Signals

Signals inherited from GObject (1)
GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Signals inherited from GListModel (1)
GListModel::items-changed

This signal is emitted whenever items were added to or removed from list. At position, removed items were removed and added items were added in their place.
