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.

Methods

connectWidgetDestroyed

Instances

((~) * signature (m ()), MonadIO m, IsAccessible a) => MethodInfo * AccessibleConnectWidgetDestroyedMethodInfo a signature

Methods

overloadedMethod :: MethodProxy AccessibleConnectWidgetDestroyedMethodInfo a -> signature -> s

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

data AccessibleGetWidgetMethodInfo

Instances

((~) * signature (m (Maybe Widget)), MonadIO m, IsAccessible a) => MethodInfo * AccessibleGetWidgetMethodInfo a signature

Methods

overloadedMethod :: MethodProxy AccessibleGetWidgetMethodInfo a -> signature -> s

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

data AccessibleSetWidgetMethodInfo

Instances

((~) * signature (Maybe b -> m ()), MonadIO m, IsAccessible a, IsWidget b) => MethodInfo * AccessibleSetWidgetMethodInfo a signature

Methods

overloadedMethod :: MethodProxy AccessibleSetWidgetMethodInfo a -> signature -> s

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.
