GI.Pango.Objects.FontFamily
Description
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.
Synopsis
- newtype FontFamily = FontFamily (ManagedPtr FontFamily)
- class (GObject o, IsDescendantOf FontFamily o) => IsFontFamily o
- toFontFamily :: (MonadIO m, IsFontFamily o) => o -> m FontFamily
- fontFamilyGetFace :: (HasCallStack, MonadIO m, IsFontFamily a) => a -> Maybe Text -> m (Maybe FontFace)
- fontFamilyGetName :: (HasCallStack, MonadIO m, IsFontFamily a) => a -> m Text
- fontFamilyIsMonospace :: (HasCallStack, MonadIO m, IsFontFamily a) => a -> m Bool
- fontFamilyIsVariable :: (HasCallStack, MonadIO m, IsFontFamily a) => a -> m Bool
- fontFamilyListFaces :: (HasCallStack, MonadIO m, IsFontFamily a) => a -> m [FontFace]

Arguments

|
| -> Maybe Text |
|
| -> m (Maybe FontFace) | Returns: the |
Gets the FontFace of family with the given name.

getName
Arguments
| :: (HasCallStack, MonadIO m, IsFontFamily a) | |
| => a |
|
| -> 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 Source #
Arguments
| :: (HasCallStack, MonadIO m, IsFontFamily a) | |
| => a |
|
| -> m Bool | Returns: |
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
Arguments
| :: (HasCallStack, MonadIO m, IsFontFamily a) | |
| => a |
|
| -> m Bool | Returns: |
A variable font is a font which has axes that can be modified to produce different faces.
Since: 1.44
listFaces
Arguments
| :: (HasCallStack, MonadIO m, IsFontFamily a) | |
| => a |
|
| -> 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.
