No description available in the introspection data.

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 ]
