atomicModifyMutVar_# :: MutVar# d a -> (a -> a) -> State# d -> (# State# d, a, a #)ghc-internal GHC.Internal.Exts Modify the contents of a MutVar#, returning the previous contents and the result of applying the given function to the previous contents.
fontDescriptionGetVariant :: (HasCallStack, MonadIO m) => FontDescription -> m Variantgi-pango GI.Pango.Structs.FontDescription Gets the variant field of a PangoFontDescription. See fontDescriptionSetVariant.
fontDescriptionGetVariations :: (HasCallStack, MonadIO m) => FontDescription -> m (Maybe Text)gi-pango GI.Pango.Structs.FontDescription Gets the variations field of a font description. See fontDescriptionSetVariations. Since: 1.42
fontDescriptionSetVariant :: (HasCallStack, MonadIO m) => FontDescription -> Variant -> m ()gi-pango GI.Pango.Structs.FontDescription Sets the variant field of a font description. The Variant can either be VariantNormal or VariantSmallCaps.
fontDescriptionSetVariations :: (HasCallStack, MonadIO m) => FontDescription -> Maybe Text -> m ()gi-pango GI.Pango.Structs.FontDescription Sets the variations field of a font description. OpenType font variations allow to select a font instance by specifying values for a number of axes, such as width or weight. The format of the variations string is AXIS1=VALUE,AXIS2=VALUE... with each AXIS a 4 character tag that identifies a font axis, and each VALUE a floating point number. Unknown axes are ignored, and values are clamped to their allowed range. Pango does not currently have a way to find supported axes of a font. Both harfbuzz and freetype have API for this. See for example hb_ot_var_get_axis_infos. Since: 1.42
fontDescriptionSetVariationsStatic :: (HasCallStack, MonadIO m) => FontDescription -> Text -> m ()gi-pango GI.Pango.Structs.FontDescription Sets the variations field of a font description. This is like fontDescriptionSetVariations, except that no copy of variations is made. The caller must make sure that the string passed in stays around until desc has been freed or the name is set again. This function can be used if variations is a static string such as a C string literal, or if desc is only needed temporarily. Since: 1.42
