{- | Copyright : Will Thompson, Iñaki García Etxebarria and Jonas Platte License : LGPL-2.1 Maintainer : Iñaki García Etxebarria (inaki@blueleaf.cc) The 'GI.Pango.Objects.FontMap.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. To create an implementation of a 'GI.Pango.Objects.FontMap.FontMap', the rendering-system specific code should allocate a larger structure that contains a nested 'GI.Pango.Objects.FontMap.FontMap', fill in the \<structfield>klass\<\/structfield> member of the nested 'GI.Pango.Objects.FontMap.FontMap' with a pointer to a appropriate 'GI.Pango.Structs.FontMapClass.FontMapClass', then call @/pango_font_map_init()/@ on the structure. The 'GI.Pango.Objects.FontMap.FontMap' structure contains one member which the implementation fills in. -} #define ENABLE_OVERLOADING (MIN_VERSION_haskell_gi_overloading(1,0,0) \ && !defined(__HADDOCK_VERSION__)) module GI.Pango.Objects.FontMap ( -- * Exported types FontMap(..) , IsFontMap , toFontMap , noFontMap , -- * Methods -- ** changed #method:changed# #if ENABLE_OVERLOADING FontMapChangedMethodInfo , #endif fontMapChanged , -- ** createContext #method:createContext# #if ENABLE_OVERLOADING FontMapCreateContextMethodInfo , #endif fontMapCreateContext , -- ** getSerial #method:getSerial# #if ENABLE_OVERLOADING FontMapGetSerialMethodInfo , #endif fontMapGetSerial , -- ** getShapeEngineType #method:getShapeEngineType# #if ENABLE_OVERLOADING FontMapGetShapeEngineTypeMethodInfo , #endif fontMapGetShapeEngineType , -- ** listFamilies #method:listFamilies# #if ENABLE_OVERLOADING FontMapListFamiliesMethodInfo , #endif fontMapListFamilies , -- ** loadFont #method:loadFont# #if ENABLE_OVERLOADING FontMapLoadFontMethodInfo , #endif fontMapLoadFont , -- ** loadFontset #method:loadFontset# #if ENABLE_OVERLOADING FontMapLoadFontsetMethodInfo , #endif fontMapLoadFontset , ) where import Data.GI.Base.ShortPrelude import qualified Data.GI.Base.ShortPrelude as SP import qualified Data.GI.Base.Overloading as O import qualified Prelude as P import qualified Data.GI.Base.Attributes as GI.Attributes import qualified Data.GI.Base.ManagedPtr as B.ManagedPtr import qualified Data.GI.Base.GClosure as B.GClosure import qualified Data.GI.Base.GError as B.GError import qualified Data.GI.Base.GVariant as B.GVariant import qualified Data.GI.Base.GValue as B.GValue import qualified Data.GI.Base.GParamSpec as B.GParamSpec import qualified Data.GI.Base.CallStack as B.CallStack import qualified Data.GI.Base.Properties as B.Properties import qualified Data.Text as T import qualified Data.ByteString.Char8 as B import qualified Data.Map as Map import qualified Foreign.Ptr as FP import qualified GHC.OverloadedLabels as OL import qualified GI.GObject.Objects.Object as GObject.Object import {-# SOURCE #-} qualified GI.Pango.Objects.Context as Pango.Context import {-# SOURCE #-} qualified GI.Pango.Objects.Font as Pango.Font import {-# SOURCE #-} qualified GI.Pango.Objects.FontFamily as Pango.FontFamily import {-# SOURCE #-} qualified GI.Pango.Objects.Fontset as Pango.Fontset import {-# SOURCE #-} qualified GI.Pango.Structs.FontDescription as Pango.FontDescription import {-# SOURCE #-} qualified GI.Pango.Structs.Language as Pango.Language -- | Memory-managed wrapper type. newtype FontMap = FontMap (ManagedPtr FontMap) foreign import ccall "pango_font_map_get_type" c_pango_font_map_get_type :: IO GType instance GObject FontMap where gobjectType = c_pango_font_map_get_type -- | Type class for types which can be safely cast to `FontMap`, for instance with `toFontMap`. class (GObject o, O.IsDescendantOf FontMap o) => IsFontMap o instance (GObject o, O.IsDescendantOf FontMap o) => IsFontMap o instance O.HasParentTypes FontMap type instance O.ParentTypes FontMap = '[GObject.Object.Object] -- | Cast to `FontMap`, for types for which this is known to be safe.
