GI.Pango.Objects.FontFamily

The FontFamily structure is used to represent a family of related font faces. The faces in a family share a common design, but differ in slant, weight, width and other aspects.

Exported types

newtype FontFamily

Memory-managed wrapper type.

Constructors

FontFamily (ManagedPtr FontFamily)

Instances

GObject FontFamily

Methods

gobjectType :: FontFamily -> IO GType

class GObject o => IsFontFamily o

Type class for types which can be safely cast to FontFamily, for instance with toFontFamily.

Instances

(GObject a, (UnknownAncestorError FontFamily a :: Constraint)) => IsFontFamily a

IsFontFamily FontFamily

Defined in GI.Pango.Objects.FontFamily

toFontFamily :: (MonadIO m, IsFontFamily o) => o -> m FontFamily

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

noFontFamily :: Maybe FontFamily

A convenience alias for Nothing :: Maybe FontFamily.

Methods

getName

fontFamilyGetName

Arguments

:: (HasCallStack, MonadIO m, IsFontFamily a)

=> a

family: a FontFamily

-> m Text

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

Gets the name of the family. The name is unique among all fonts for the font backend and can be used in a FontDescription to specify that a face from this family is desired.

isMonospace

fontFamilyIsMonospace

Arguments

:: (HasCallStack, MonadIO m, IsFontFamily a)

=> a

family: a FontFamily

-> m Bool

Returns: True if the family is monospace.

A monospace font is a font designed for text display where the the characters form a regular grid. For Western languages this would mean that the advance width of all characters are the same, but this categorization also includes Asian fonts which include double-width characters: characters that occupy two grid cells. unicharIswide returns a result that indicates whether a character is typically double-width in a monospace font.

The best way to find out the grid-cell size is to call fontMetricsGetApproximateDigitWidth, since the results of fontMetricsGetApproximateCharWidth may be affected by double-width characters.

listFaces

fontFamilyListFaces

Arguments

:: (HasCallStack, MonadIO m, IsFontFamily a)

=> a

family: a FontFamily

-> m [FontFace]

Lists the different font faces that make up family. The faces in a family share a common design, but differ in slant, weight, width and other aspects.
