GI.Atk.Objects.NoOpObject
Contents
Description
An AtkNoOpObject is an AtkObject which purports to implement all ATK interfaces. It is the type of AtkObject which is created if an accessible object is requested for an object type for which no factory type is specified.
Synopsis
- newtype NoOpObject = NoOpObject (ManagedPtr NoOpObject)
- class (GObject o, IsDescendantOf NoOpObject o) => IsNoOpObject o
- toNoOpObject :: (MonadIO m, IsNoOpObject o) => o -> m NoOpObject
- noNoOpObject :: Maybe NoOpObject
- noOpObjectNew :: (HasCallStack, MonadIO m, IsObject a) => a -> m NoOpObject
Exported types

class (GObject o, IsDescendantOf NoOpObject o) => IsNoOpObject o Source #
Type class for types which can be safely cast to NoOpObject, for instance with toNoOpObject.

toNoOpObject :: (MonadIO m, IsNoOpObject o) => o -> m NoOpObject Source #
Cast to NoOpObject, for types for which this is known to be safe. For general casts, use castTo.
noNoOpObject :: Maybe NoOpObject Source #
A convenience alias for Nothing :: Maybe NoOpObject.
