GI.GObject.Structs.Parameter

The GParameter struct is an auxiliary structure used to hand parameter name/value pairs to objectNewv.

Exported types

newtype Parameter

Memory-managed wrapper type.

Constructors

Parameter (ManagedPtr Parameter)

Instances

WrappedPtr Parameter

Defined in GI.GObject.Structs.Parameter

Methods

wrappedPtrCalloc :: IO (Ptr Parameter)

wrappedPtrCopy :: Parameter -> IO Parameter

wrappedPtrFree :: Maybe (GDestroyNotify Parameter)

tag ~ AttrSet => Constructible Parameter tag

Defined in GI.GObject.Structs.Parameter

Methods

new :: MonadIO m => (ManagedPtr Parameter -> Parameter) -> [AttrOp Parameter tag] -> m Parameter

newZeroParameter :: MonadIO m => m Parameter

Construct a Parameter struct initialized to zero.

noParameter :: Maybe Parameter

A convenience alias for Nothing :: Maybe Parameter.

Properties

name

the parameter name

clearParameterName :: MonadIO m => Parameter -> m ()

Set the value of the “name” field to Nothing. When overloading is enabled, this is equivalent to

clear #name

getParameterName :: MonadIO m => Parameter -> m (Maybe Text)

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

get parameter #name

setParameterName :: MonadIO m => Parameter -> CString -> m ()

Set the value of the “name” field. When overloading is enabled, this is equivalent to

set parameter [ #name := value ]

value

the parameter value

getParameterValue :: MonadIO m => Parameter -> m GValue

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

get parameter #value
