type ParentTypes FontFace = Object ': ([] :: [Type])

class (GObject o, IsDescendantOf FontFace o) => IsFontFace o

Type class for types which can be safely cast to FontFace, for instance with toFontFace.

Instances

(GObject o, IsDescendantOf FontFace o) => IsFontFace o

Defined in GI.Pango.Objects.FontFace

toFontFace :: (MonadIO m, IsFontFace o) => o -> m FontFace

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

noFontFace :: Maybe FontFace

A convenience alias for Nothing :: Maybe FontFace.

Methods

describe

fontFaceDescribe

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a FontFace

-> m FontDescription

Returns: a newly-created FontDescription structure holding the description of the face. Use fontDescriptionFree to free the result.

Returns the family, style, variant, weight and stretch of a FontFace. The size field of the resulting font description will be unset.

getFaceName

fontFaceGetFaceName

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a FontFace.

-> m Text

Returns: the face name for the face. This string is owned by the face object and must not be modified or freed.

Gets a name representing the style of this face among the different faces in the FontFamily for the face. This name is unique among all faces in the family and is suitable for displaying to users.

isSynthesized

fontFaceIsSynthesized

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a FontFace

-> m Bool

Returns: whether face is synthesized.

Returns whether a FontFace is synthesized by the underlying font rendering engine from another face, perhaps by shearing, emboldening, or lightening it.

Since: 1.18

listSizes

fontFaceListSizes

Arguments

:: (HasCallStack, MonadIO m, IsFontFace a)

=> a

face: a FontFace.

-> m (Maybe [Int32])

List the available sizes for a font. This is only applicable to bitmap fonts. For scalable fonts, stores Nothing at the location pointed to by sizes and 0 at the location pointed to by nSizes. The sizes returned are in Pango units and are sorted in ascending order.
