GI.Pango.Structs.AttrClass

The AttrClass structure stores the type and operations for a particular type of attribute. The functions in this structure should not be called directly. Instead, one should use the wrapper functions provided for Attribute.

Exported types

newtype AttrClass

Memory-managed wrapper type.

Constructors

AttrClass (ManagedPtr AttrClass)

Instances

Eq AttrClass

Defined in GI.Pango.Structs.AttrClass

Methods

(==) :: AttrClass -> AttrClass -> Bool

(/=) :: AttrClass -> AttrClass -> Bool

WrappedPtr AttrClass

Defined in GI.Pango.Structs.AttrClass

Methods

wrappedPtrCalloc :: IO (Ptr AttrClass)

wrappedPtrCopy :: AttrClass -> IO AttrClass

wrappedPtrFree :: Maybe (GDestroyNotify AttrClass)

tag ~ 'AttrSet => Constructible AttrClass tag

Defined in GI.Pango.Structs.AttrClass

Methods

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

newZeroAttrClass :: MonadIO m => m AttrClass

Construct a AttrClass struct initialized to zero.

noAttrClass :: Maybe AttrClass

A convenience alias for Nothing :: Maybe AttrClass.

Methods

Overloaded methods

Properties

destroy

No description available in the introspection data.

clearAttrClassDestroy :: MonadIO m => AttrClass -> m ()

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

clear #destroy

getAttrClassDestroy :: MonadIO m => AttrClass -> m (Maybe AttrClassDestroyFieldCallback)

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

get attrClass #destroy

setAttrClassDestroy :: MonadIO m => AttrClass -> FunPtr C_AttrClassDestroyFieldCallback -> m ()

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

set attrClass [ #destroy := value ]

equal

No description available in the introspection data.

clearAttrClassEqual :: MonadIO m => AttrClass -> m ()

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

clear #equal

getAttrClassEqual :: MonadIO m => AttrClass -> m (Maybe AttrClassEqualFieldCallback)

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

get attrClass #equal

setAttrClassEqual :: MonadIO m => AttrClass -> FunPtr C_AttrClassEqualFieldCallback -> m ()

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

set attrClass [ #equal := value ]

type

the type ID for this attribute

getAttrClassType :: MonadIO m => AttrClass -> m AttrType

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

get attrClass #type

setAttrClassType :: MonadIO m => AttrClass -> AttrType -> m ()

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

set attrClass [ #type := value ]
