GI.Atk.Objects.Misc

A set of utility functions for thread locking. This interface and all his related methods are deprecated since 2.12.

Exported types

newtype Misc

Memory-managed wrapper type.

Constructors

Misc (ManagedPtr Misc)

Instances

GObject Misc

Defined in GI.Atk.Objects.Misc

Methods

gobjectType :: IO GType

HasParentTypes Misc

Defined in GI.Atk.Objects.Misc

type ParentTypes Misc

Defined in GI.Atk.Objects.Misc

type ParentTypes Misc = Object ': ([] :: [Type])

class (GObject o, IsDescendantOf Misc o) => IsMisc o

Type class for types which can be safely cast to Misc, for instance with toMisc.

Instances

(GObject o, IsDescendantOf Misc o) => IsMisc o

Defined in GI.Atk.Objects.Misc

toMisc :: (MonadIO m, IsMisc o) => o -> m Misc

Cast to Misc, for types for which this is known to be safe. For general casts, use castTo.

noMisc :: Maybe Misc

A convenience alias for Nothing :: Maybe Misc.

Methods

getInstance

miscGetInstance

Arguments

:: (HasCallStack, MonadIO m)

=> m Misc

Returns: The singleton instance of AtkMisc for this application.

Deprecated: Since 2.12.

Obtain the singleton instance of AtkMisc for this application.

Since: 1.13

threadsEnter

miscThreadsEnter

Arguments

:: (HasCallStack, MonadIO m, IsMisc a)

=> a

misc: an AtkMisc instance for this application.

-> m ()

Deprecated: Since 2.12.

Take the thread mutex for the GUI toolkit, if one exists. (This method is implemented by the toolkit ATK implementation layer; for instance, for GTK+, GAIL implements this via GDK_THREADS_ENTER).

Since: 1.13

threadsLeave

miscThreadsLeave

Arguments

:: (HasCallStack, MonadIO m, IsMisc a)

=> a

misc: an AtkMisc instance for this application.

-> m ()

Deprecated: Since 2.12.

Release the thread mutex for the GUI toolkit, if one exists. This method, and atk_misc_threads_enter, are needed in some situations by threaded application code which services ATK requests, since fulfilling ATK requests often requires calling into the GUI toolkit. If a long-running or potentially blocking call takes place inside such a block, it should be bracketed by atk_misc_threads_leave/atk_misc_threads_enter calls. (This method is implemented by the toolkit ATK implementation layer; for instance, for GTK+, GAIL implements this via GDK_THREADS_LEAVE).

Since: 1.13
