Constructing GValues
Haskell-side representation of a GValue.
Constructors
| GValue (ManagedPtr GValue) |
class IsGValue a where Source #
A convenience class for marshaling back and forth between Haskell
values and GValues.
Instances
data GValueConstruct o Source #
A type holding a GValue with an associated label. It is
parameterized by a phantom type encoding the target type for the
GValue (useful when constructing properties).
Constructors
| GValueConstruct String GValue |
buildGValue :: GType -> (GValue -> a -> IO ()) -> a -> IO GValue Source #
A convenience function for building a new GValue and setting the initial value.
Setters and getters
take_stablePtr :: Ptr GValue -> StablePtr a -> IO () Source #
Like set_stablePtr, but the GValue takes ownership of the StablePtr
