GI.Pango.Objects.FontFamily

Description

A PangoFontFamily is used to represent a family of related font faces.

The font faces in a family share a common design, but differ in slant, weight, width or other aspects.

Synopsis

Exported types

newtype FontFamily Source #

Memory-managed wrapper type.

class (GObject o, IsDescendantOf FontFamily o) => IsFontFamily o Source #

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

Instances

(GObject o, IsDescendantOf FontFamily o) => IsFontFamily o Source # 
Instance details

Defined in GI.Pango.Objects.FontFamily

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

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

Methods

getFace

fontFamilyGetFace Source #

Arguments

:: (HasCallStack, MonadIO m, IsFontFamily a) 
=> a

family: a PangoFontFamily

-> Maybe Text

name: the name of a face. If the name is Nothing, the family's default face (fontconfig calls it "Regular") will be returned.

-> m (Maybe FontFace)

Returns: the PangoFontFace, or Nothing if no face with the given name exists.

Gets the PangoFontFace of family with the given name.

Since: 1.46

getName

fontFamilyGetName Source #

Arguments

:: (HasCallStack, MonadIO m, IsFontFamily a) 
=> a

family: a PangoFontFamily

-> 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 PangoFontDescription to specify that a face from this family is desired.

isMonospace

fontFamilyIsMonospace Source #

Arguments

:: (HasCallStack, MonadIO m, IsFontFamily a) 
=> a

family: a PangoFontFamily

-> 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.

Since: 1.4

isVariable

fontFamilyIsVariable Source #

Arguments

:: (HasCallStack, MonadIO m, IsFontFamily a) 
=> a

family: a PangoFontFamily

-> m Bool

Returns: True if the family is variable

A variable font is a font which has axes that can be modified to produce different faces.

Such axes are also known as _variations_; see fontDescriptionSetVariations for more information.

Since: 1.44

listFaces

fontFamilyListFaces Source #

Arguments

:: (HasCallStack, MonadIO m, IsFontFamily a) 
=> a

family: a PangoFontFamily

-> 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.
