GI.Pango.Structs.AttrFloat
Description
The #PangoAttrFloat structure is used to represent attributes with a float or double value.
- newtype AttrFloat = AttrFloat (ForeignPtr AttrFloat)
- newZeroAttrFloat :: MonadIO m => m AttrFloat
- noAttrFloat :: Maybe AttrFloat
- attrFloatAttr :: AttrLabelProxy "attr"
- attrFloatClearAttr :: MonadIO m => AttrFloat -> m ()
- attrFloatReadAttr :: MonadIO m => AttrFloat -> m (Maybe Attribute)
- attrFloatWriteAttr :: MonadIO m => AttrFloat -> Ptr Attribute -> m ()
- attrFloatReadValue :: MonadIO m => AttrFloat -> m Double
- attrFloatValue :: AttrLabelProxy "value"
- attrFloatWriteValue :: MonadIO m => AttrFloat -> Double -> m ()
