GI.Pango.Structs.AttrIterator
Contents
Description
The #PangoAttrIterator structure is used to represent an iterator through a #PangoAttrList. A new iterator is created with pango_attr_list_get_iterator(). Once the iterator is created, it can be advanced through the style changes in the text using pango_attr_iterator_next(). At each style change, the range of the current style segment and the attributes currently in effect can be queried.
- newtype AttrIterator = AttrIterator (ForeignPtr AttrIterator)
- noAttrIterator :: Maybe AttrIterator
- attrIteratorDestroy :: MonadIO m => AttrIterator -> m ()
- attrIteratorGetAttrs :: MonadIO m => AttrIterator -> m [Attribute]
- attrIteratorGetFont :: MonadIO m => AttrIterator -> FontDescription -> Maybe Language -> [Attribute] -> m ()
- attrIteratorNext :: MonadIO m => AttrIterator -> m Bool
- attrIteratorRange :: MonadIO m => AttrIterator -> m (Int32, Int32)
