Accessible

open class Accessible : AccessibleProtocol

GtkAccessible is an interface for describing UI elements for Assistive Technologies.

Every accessible implementation has:

  • a “role”, represented by a value of the [enumGtk.AccessibleRole] enumeration
  • an “attribute”, represented by a set of [enumGtk.AccessibleState], [enumGtk.AccessibleProperty] and [enumGtk.AccessibleRelation] values

The role cannot be changed after instantiating a GtkAccessible implementation.

The attributes are updated every time a UI element’s state changes in a way that should be reflected by assistive technologies. For instance, if a GtkWidget visibility changes, the GTK_ACCESSIBLE_STATE_HIDDEN state will also change to reflect the [propertyGtk.Widget:visible] property.

The Accessible type acts as an owner of an underlying GtkAccessible instance. It provides the methods that can operate on this data type through AccessibleProtocol conformance. Use Accessible as a strong reference or owner of a GtkAccessible instance.

  • ptr 
    Untyped pointer to the underlying `GtkAccessible` instance.

    For type-safe access, use the generated, typed pointer accessible_ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

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

    Declaration

    Swift

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

    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 Accessible instance.

    Declaration

    Swift

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

    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 Accessible instance.

    Declaration

    Swift

    @inlinable
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 Accessible instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional 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 Accessible instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Accessible instance.

    Declaration

    Swift

    @inlinable
public init!(_ op: UnsafeMutablePointer<GtkAccessible>?)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from the underlying C data type. GtkAccessible does not allow reference counting, so despite the name no actual retaining will occur. i.e., ownership is transferred to the Accessible instance.

    Declaration

    Swift

    @inlinable
public init(retaining op: UnsafeMutablePointer<GtkAccessible>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements AccessibleProtocol GtkAccessible does not allow reference counting.

    Declaration

    Swift

    @inlinable
public init<T>(_ other: T) where T : AccessibleProtocol

    Parameters

    other

    an instance of a related type that implements AccessibleProtocol

  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to AccessibleProtocol.

    Declaration

    Parameters

    cPointer
