GI.Pango.Structs.AttrFontDesc

The AttrFontDesc structure is used to store an attribute that sets all aspects of the font description at once.

Exported types

newtype AttrFontDesc

Memory-managed wrapper type.

Constructors

AttrFontDesc (ManagedPtr AttrFontDesc)

Instances

WrappedPtr AttrFontDesc

Methods

wrappedPtrCalloc :: IO (Ptr AttrFontDesc)

wrappedPtrCopy :: AttrFontDesc -> IO AttrFontDesc

wrappedPtrFree :: Maybe (FunPtr (Ptr AttrFontDesc -> IO ()))

tag ~ AttrSet => Constructible AttrFontDesc tag

Defined in GI.Pango.Structs.AttrFontDesc

Methods

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

newZeroAttrFontDesc :: MonadIO m => m AttrFontDesc

Construct a AttrFontDesc struct initialized to zero.

noAttrFontDesc :: Maybe AttrFontDesc

A convenience alias for Nothing :: Maybe AttrFontDesc.

Methods

new

attrFontDescNew

Arguments

:: (HasCallStack, MonadIO m)

=> FontDescription

desc: the font description

-> m Attribute

Returns: the newly allocated Attribute, which should be freed with attributeDestroy.

Create a new font description attribute. This attribute allows setting family, style, weight, variant, stretch, and size simultaneously.

Properties

attr

the common portion of the attribute

getAttrFontDescAttr :: MonadIO m => AttrFontDesc -> m Attribute

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

get attrFontDesc #attr

desc

the font description which is the value of this attribute

clearAttrFontDescDesc :: MonadIO m => AttrFontDesc -> m ()

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

clear #desc

getAttrFontDescDesc :: MonadIO m => AttrFontDesc -> m (Maybe FontDescription)

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

get attrFontDesc #desc

setAttrFontDescDesc :: MonadIO m => AttrFontDesc -> Ptr FontDescription -> m ()

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

set attrFontDesc [ #desc := value ]
