Description

The AttrShape structure is used to represent attributes which impose shape restrictions.

Synopsis

newtype AttrShape = AttrShape (ManagedPtr AttrShape)
newZeroAttrShape :: MonadIO m => m AttrShape
noAttrShape :: Maybe AttrShape
attrShapeNew :: (HasCallStack, MonadIO m) => Rectangle -> Rectangle -> m Attribute
getAttrShapeAttr :: MonadIO m => AttrShape -> m Attribute
clearAttrShapeCopyFunc :: MonadIO m => AttrShape -> m ()
getAttrShapeCopyFunc :: MonadIO m => AttrShape -> m (Maybe AttrDataCopyFunc_WithClosures)
setAttrShapeCopyFunc :: MonadIO m => AttrShape -> FunPtr C_AttrDataCopyFunc -> m ()
clearAttrShapeData :: MonadIO m => AttrShape -> m ()
getAttrShapeData :: MonadIO m => AttrShape -> m (Ptr ())
setAttrShapeData :: MonadIO m => AttrShape -> Ptr () -> m ()
clearAttrShapeDestroyFunc :: MonadIO m => AttrShape -> m ()
getAttrShapeDestroyFunc :: MonadIO m => AttrShape -> m (Maybe DestroyNotify)
setAttrShapeDestroyFunc :: MonadIO m => AttrShape -> FunPtr C_DestroyNotify -> m ()
getAttrShapeInkRect :: MonadIO m => AttrShape -> m Rectangle
getAttrShapeLogicalRect :: MonadIO m => AttrShape -> m Rectangle

newZeroAttrShape :: MonadIO m => m AttrShape Source #

Construct a AttrShape struct initialized to zero.

noAttrShape :: Maybe AttrShape Source #

A convenience alias for Nothing :: Maybe AttrShape.

Methods

new

attrShapeNew Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Rectangle	`inkRect`: ink rectangle to assign to each character
-> Rectangle	`logicalRect`: logical rectangle to assign to each character
-> m Attribute	Returns: the newly allocated `Attribute`, which should be freed with `attributeDestroy`.

Create a new shape attribute. A shape is used to impose a particular ink and logical rectangle on the result of shaping a particular glyph. This might be used, for instance, for embedding a picture or a widget inside a Layout.

Properties

attr

the common portion of the attribute

getAttrShapeAttr :: MonadIO m => AttrShape -> m Attribute Source #

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

get attrShape #attr

copyFunc

copy function for the user data

clearAttrShapeCopyFunc :: MonadIO m => AttrShape -> m () Source #

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

clear #copyFunc

getAttrShapeCopyFunc :: MonadIO m => AttrShape -> m (Maybe AttrDataCopyFunc_WithClosures) Source #

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

get attrShape #copyFunc

setAttrShapeCopyFunc :: MonadIO m => AttrShape -> FunPtr C_AttrDataCopyFunc -> m () Source #

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

set attrShape [ #copyFunc := value ]

data

user data set (see pango_attr_shape_new_with_data())

clearAttrShapeData :: MonadIO m => AttrShape -> m () Source #

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

clear #data

getAttrShapeData :: MonadIO m => AttrShape -> m (Ptr ()) Source #

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

get attrShape #data

setAttrShapeData :: MonadIO m => AttrShape -> Ptr () -> m () Source #

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

set attrShape [ #data := value ]

destroyFunc

destroy function for the user data

clearAttrShapeDestroyFunc :: MonadIO m => AttrShape -> m () Source #

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

clear #destroyFunc

getAttrShapeDestroyFunc :: MonadIO m => AttrShape -> m (Maybe DestroyNotify) Source #

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

get attrShape #destroyFunc

setAttrShapeDestroyFunc :: MonadIO m => AttrShape -> FunPtr C_DestroyNotify -> m () Source #

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

set attrShape [ #destroyFunc := value ]

inkRect

the ink rectangle to restrict to

getAttrShapeInkRect :: MonadIO m => AttrShape -> m Rectangle Source #

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

get attrShape #inkRect

logicalRect

the logical rectangle to restrict to

getAttrShapeLogicalRect :: MonadIO m => AttrShape -> m Rectangle Source #

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

get attrShape #logicalRect
