GI.Pango.Structs.AttrClass

The PangoAttrClass 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 PangoAttribute.

Exported types

newtype AttrClass

Memory-managed wrapper type.

Constructors

AttrClass (ManagedPtr AttrClass)

Methods

Properties

copy

No description available in the introspection data.

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

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

clear #copy

getAttrClassCopy :: MonadIO m => AttrClass -> m (Maybe AttrClassCopyFieldCallback)

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

get attrClass #copy

setAttrClassCopy :: MonadIO m => AttrClass -> FunPtr C_AttrClassCopyFieldCallback -> m ()

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

set attrClass [ #copy := value ]

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 ]
