GI.Pango.Structs.AttrShape

The AttrShape structure is used to represent attributes which impose shape restrictions.

Exported types

newtype AttrShape

Constructors

AttrShape (ManagedPtr AttrShape)

Instances

WrappedPtr AttrShape

Methods

wrappedPtrCalloc :: IO (Ptr AttrShape)

wrappedPtrCopy :: AttrShape -> IO AttrShape

wrappedPtrFree :: Maybe (FunPtr (Ptr AttrShape -> IO ()))

(~) AttrOpTag tag AttrSet => Constructible AttrShape tag

Methods

new :: MonadIO m => (ManagedPtr AttrShape -> AttrShape) -> [AttrOp AttrShape tag] -> m AttrShape

newZeroAttrShape :: MonadIO m => m AttrShape

Construct a AttrShape struct initialized to zero.

noAttrShape :: Maybe AttrShape

Methods

new

attrShapeNew

Arguments

:: (HasCallStack, MonadIO m)

=> Rectangle

inkRect: ink rectangle to assign to each character

-> Rectangle

logicalRect: logical rectangle to assign to each character

-> m Attribute

Returns: the newly allocated Attribute, which should be freed with attributeDestroy.

Create a new shape attribute. A shape is used to impose a particular ink and logical rectangle on the result of shaping a particular glyph. This might be used, for instance, for embedding a picture or a widget inside a Layout.
