constructValueObjectValue :: IsValueObject o => GValue -> IO (GValueConstruct o)

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

getValueObjectValue :: (MonadIO m, IsValueObject o) => o -> m GValue

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

get valueObject #value
