Diagrams.Backend.HsQML.DiagramObj.Type

The DiagramObj type, together with a corresponding DefaultClass instance that defines the necessary methods and signals for use by QML.

Documentation

newtype DiagramObj a

The type to which the parts of a diagram are rendered. The end result of rendering is always a DiagramObj (). The monoid instance sequences actions on the same argument, with noop as identity. As DiagramObj is a wrapper over a function to IO, Functor, Applicative, Monad, and MonadIO instances are defined in an expected way.
