GI.Pango.Structs.AttrFontFeatures
Description
The PangoAttrFontFeatures structure is used to represent OpenType
font features as an attribute.
Since: 1.38
Synopsis
- newtype AttrFontFeatures = AttrFontFeatures (ManagedPtr AttrFontFeatures)
- newZeroAttrFontFeatures :: MonadIO m => m AttrFontFeatures
- attrFontFeaturesNew :: (HasCallStack, MonadIO m) => Text -> m Attribute
- getAttrFontFeaturesAttr :: MonadIO m => AttrFontFeatures -> m Attribute
- clearAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> m ()
- getAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> m (Maybe Text)
- setAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> CString -> m ()

Methods

Arguments

| => Text |
|
| -> m Attribute | Returns: the newly allocated
|
Create a new font features tag attribute.
You can use this attribute to select OpenType font features like small-caps, alternative glyphs, ligatures, etc. for fonts that support them.

Properties
attr
the common portion of the attribute
getAttrFontFeaturesAttr :: MonadIO m => AttrFontFeatures -> m Attribute Source #
Get the value of the “attr” field.
When overloading is enabled, this is equivalent to
get attrFontFeatures #attr
features
the featues, as a string in CSS syntax
clearAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> m () Source #
Set the value of the “features” field to Nothing.
When overloading is enabled, this is equivalent to
clear #features
getAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> m (Maybe Text) Source #
Get the value of the “features” field.
When overloading is enabled, this is equivalent to
get attrFontFeatures #features
setAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> CString -> m () Source #
Set the value of the “features” field.
When overloading is enabled, this is equivalent to
setattrFontFeatures [ #features:=value ]
