Description

The AttrSize structure is used to represent attributes which set font size.

Synopsis

newtype AttrSize = AttrSize (ManagedPtr AttrSize)
newZeroAttrSize :: MonadIO m => m AttrSize
attrSizeNew :: (HasCallStack, MonadIO m) => Int32 -> m Attribute
attrSizeNewAbsolute :: (HasCallStack, MonadIO m) => Int32 -> m Attribute
getAttrSizeAbsolute :: MonadIO m => AttrSize -> m Word32
setAttrSizeAbsolute :: MonadIO m => AttrSize -> Word32 -> m ()
getAttrSizeAttr :: MonadIO m => AttrSize -> m Attribute
getAttrSizeSize :: MonadIO m => AttrSize -> m Int32
setAttrSizeSize :: MonadIO m => AttrSize -> Int32 -> m ()

newZeroAttrSize :: MonadIO m => m AttrSize Source #

Construct a AttrSize struct initialized to zero.

Methods

new

attrSizeNew Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Int32	`size`: the font size, in `PANGO_SCALEths` of a point.
-> m Attribute	Returns: the newly allocated `Attribute`, which should be freed with `attributeDestroy`.

Create a new font-size attribute in fractional points.

newAbsolute

attrSizeNewAbsolute Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Int32	`size`: the font size, in `PANGO_SCALEths` of a device unit.
-> m Attribute	Returns: the newly allocated `Attribute`, which should be freed with `attributeDestroy`.

Create a new font-size attribute in device units.

Since: 1.8

Properties

whether the font size is in device units or points. This field is only present for compatibility with Pango-1.8.0 (AttrTypeAbsoluteSize was added in 1.8.1); and always will be False for AttrTypeSize and True for AttrTypeAbsoluteSize.

getAttrSizeAbsolute :: MonadIO m => AttrSize -> m Word32 Source #

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

get attrSize #absolute

setAttrSizeAbsolute :: MonadIO m => AttrSize -> Word32 -> m () Source #

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

set attrSize [ #absolute := value ]

attr

the common portion of the attribute

getAttrSizeAttr :: MonadIO m => AttrSize -> m Attribute Source #

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

get attrSize #attr

size

size of font, in units of 1/SCALE of a point (for AttrTypeSize) or of a device uni (for AttrTypeAbsoluteSize)

getAttrSizeSize :: MonadIO m => AttrSize -> m Int32 Source #

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

get attrSize #size

setAttrSizeSize :: MonadIO m => AttrSize -> Int32 -> m () Source #

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

set attrSize [ #size := value ]
