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.
disownGValue :: GValue -> IO (Ptr GValue) Source #
Disown a GValue, i.e. do not unref the underlying object when
the Haskell object is garbage collected.
newGValueFromPtr :: Ptr GValue -> IO GValue Source #
Construct a Haskell wrapper for the given GValue, making a
copy.
unsetGValue :: Ptr GValue -> IO () Source #
Unset the GValue, freeing all resources associated to it.
Packing GValues into arrays
packGValueArray :: [GValue] -> IO (Ptr GValue) Source #
Pack the given list of GValues contiguously into a C array
unpackGValueArrayWithLength :: Integral a => a -> Ptr GValue -> IO [GValue] Source #
Unpack an array of contiguous GValues into a list of GValues.
mapGValueArrayWithLength :: Integral a => a -> (Ptr GValue -> IO c) -> Ptr GValue -> IO () Source #
Map over the GValues inside a C array.
Setters and getters
set_stablePtr :: GValue -> StablePtr a -> IO () Source #
Set the value of GValue containing a StablePtr
get_stablePtr :: GValue -> IO (StablePtr a) Source #
Get the value of a GValue containing a StablePtr
take_stablePtr :: Ptr GValue -> StablePtr a -> IO () Source #
Like set_stablePtr, but the GValue takes ownership of the StablePtr
