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

newtype NoOpObject Source #

Memory-managed wrapper type.

Constructors

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.

Arguments

:: (HasCallStack, MonadIO m, IsObject a)
=> a	`obj`: a `Object`
-> m NoOpObject	Returns: a default (non-functioning stub) `Object`

Provides a default (non-functioning stub) Object. Application maintainers should not use this method.
