GI.Gtk.Objects.Accessible

The Accessible class is the base class for accessible implementations for Widget subclasses. It is a thin wrapper around Object, which adds facilities for associating a widget with its accessible object.

An accessible implementation for a third-party widget should derive from Accessible and implement the suitable interfaces from ATK, such as Text or Selection. To establish the connection between the widget class and its corresponding acccessible implementation, override the get_accessible vfunc in WidgetClass.

toAccessible :: (MonadIO m, IsAccessible o) => o -> m Accessible

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

noAccessible :: Maybe Accessible

A convenience alias for Nothing :: Maybe Accessible.

Methods

connectWidgetDestroyed

accessibleConnectWidgetDestroyed

Arguments

:: (HasCallStack, MonadIO m, IsAccessible a)

=> a

accessible: a Accessible

-> m ()

Deprecated: (Since version 3.4)Use accessibleSetWidget and its vfuncs.

This function specifies the callback function to be called when the widget corresponding to a GtkAccessible is destroyed.

getWidget

accessibleGetWidget

Arguments

:: (HasCallStack, MonadIO m, IsAccessible a)

=> a

accessible: a Accessible

-> m (Maybe Widget)

Returns: pointer to the Widget corresponding to the Accessible, or Nothing.

Gets the Widget corresponding to the Accessible. The returned widget does not have a reference added, so you do not need to unref it.

Since: 2.22

setWidget

accessibleSetWidget

Arguments

:: (HasCallStack, MonadIO m, IsAccessible a, IsWidget b)

=> a

accessible: a Accessible

-> Maybe b

widget: a Widget or Nothing to unset

-> m ()

Sets the Widget corresponding to the Accessible.

accessible will not hold a reference to widget. It is the caller’s responsibility to ensure that when widget is destroyed, the widget is unset by calling this function again with widget set to Nothing.

Since: 2.22

Properties

widget

No description available in the introspection data.

clearAccessibleWidget :: (MonadIO m, IsAccessible o) => o -> m ()

Set the value of the “widget” property to Nothing. When overloading is enabled, this is equivalent to

clear #widget

constructAccessibleWidget :: (IsAccessible o, IsWidget a) => a -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “widget” property. This is rarely needed directly, but it is used by new.

getAccessibleWidget :: (MonadIO m, IsAccessible o) => o -> m (Maybe Widget)

Get the value of the “widget” property. When overloading is enabled, this is equivalent to

get accessible #widget

setAccessibleWidget :: (MonadIO m, IsAccessible o, IsWidget a) => o -> a -> m ()

Set the value of the “widget” property. When overloading is enabled, this is equivalent to

set accessible [ #widget := value ]
