gobjectType :: VideoDirection -> IO GType

IsObject VideoDirection

IsVideoDirection VideoDirection

noVideoDirection :: Maybe VideoDirection

A convenience alias for Nothing :: Maybe VideoDirection.

class GObject o => IsVideoDirection o

Type class for types which can be safely cast to VideoDirection, for instance with toVideoDirection.

Instances

(GObject a, UnknownAncestorError Constraint VideoDirection a) => IsVideoDirection a

IsVideoDirection VideoDirection

toVideoDirection :: (MonadIO m, IsVideoDirection o) => o -> m VideoDirection

constructVideoDirectionVideoDirection :: IsVideoDirection o => VideoOrientationMethod -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “video-direction” property. This is rarely needed directly, but it is used by new.

getVideoDirectionVideoDirection :: (MonadIO m, IsVideoDirection o) => o -> m VideoOrientationMethod

Get the value of the “video-direction” property. When overloading is enabled, this is equivalent to

get videoDirection #videoDirection

setVideoDirectionVideoDirection :: (MonadIO m, IsVideoDirection o) => o -> VideoOrientationMethod -> m ()

Set the value of the “video-direction” property. When overloading is enabled, this is equivalent to

set videoDirection [ #videoDirection := value ]
