Description

Font is an interface exported by fonts for use with Cairo. The actual type of the font will depend on the particular font technology Cairo was compiled to use.

Since: 1.18

Synopsis

newtype Font = Font (ManagedPtr Font)
noFont :: Maybe Font
class (GObject o, IsDescendantOf Font o) => IsFont o
toFont :: (MonadIO m, IsFont o) => o -> m Font
fontGetScaledFont :: (HasCallStack, MonadIO m, IsFont a) => a -> m (Maybe ScaledFont)

Exported types

newtype Font Source #

Memory-managed wrapper type.

Constructors

noFont :: Maybe Font Source #

A convenience alias for Nothing :: Maybe Font.

class (GObject o, IsDescendantOf Font o) => IsFont o Source #

Type class for types which can be safely cast to Font, for instance with toFont.

Instances

(GObject o, IsDescendantOf Font o) => IsFont o Source #
Instance details Defined in GI.PangoCairo.Interfaces.Font

toFont :: (MonadIO m, IsFont o) => o -> m Font Source #

Cast to Font, for types for which this is known to be safe. For general casts, use castTo.

Methods

fontGetScaledFont Source #

Arguments

:: (HasCallStack, MonadIO m, IsFont a)
=> a	`font`: a `Font` from a `FontMap`
-> m (Maybe ScaledFont)	Returns: the `ScaledFont` used by `font`, or `Nothing` if `font` is `Nothing`.

Gets the ScaledFont used by font. The scaled font can be referenced and kept using cairo_scaled_font_reference().
