GI.Pango.Objects.EngineLang
Contents
Description
The EngineLang class is implemented by engines that
customize the rendering-system independent part of the
Pango pipeline for a particular script or language. For
instance, a custom EngineLang could be provided for
Thai to implement the dictionary-based word boundary
lookups needed for that language.
Synopsis
- newtype EngineLang = EngineLang (ManagedPtr EngineLang)
- class GObject o => IsEngineLang o
- toEngineLang :: (MonadIO m, IsEngineLang o) => o -> m EngineLang
- noEngineLang :: Maybe EngineLang
Exported types

toEngineLang :: (MonadIO m, IsEngineLang o) => o -> m EngineLang Source #
Cast to EngineLang, for types for which this is known to be safe. For general casts, use castTo.
noEngineLang :: Maybe EngineLang Source #
A convenience alias for Nothing :: Maybe EngineLang.
