Object

open class Object : GLibObject.Object, ObjectProtocol

This class is the primary class for accessibility support via the Accessibility ToolKit (ATK). Objects which are instances of AtkObject (or instances of AtkObject-derived types) are queried for properties which relate basic (and generic) properties of a UI component such as name and description. Instances of AtkObject may also be queried as to whether they implement other ATK interfaces (e.g. AtkAction, AtkComponent, etc.), as appropriate to the role which a given UI component plays in a user interface.

All UI components in an application which provide useful information or services to the user must provide corresponding AtkObject instances on request (in GTK+, for instance, usually on a call to gtk_widget_get_accessible ()), either via ATK support built into the toolkit for the widget class or ancestor class, or in the case of custom widgets, if the inherited AtkObject implementation is insufficient, via instances of a new AtkObject subclass.

See also: AtkObjectFactory, AtkRegistry. (GTK+ users see also GtkAccessible).

The Object type acts as a reference-counted owner of an underlying AtkObject instance. It provides the methods that can operate on this data type through ObjectProtocol conformance. Use Object as a strong reference or owner of a AtkObject instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Object instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<AtkObject>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Object instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<AtkObject>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Object instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Object instance.

    Declaration

    Swift

    @inlinable
override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object

    @inlinable
public init!(_ op: UnsafePointer<AtkObject>?)

    Parameters

    op

    pointer to the underlying object
