AccessibleRef

public struct AccessibleRef : 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 AccessibleRef type acts as a lightweight Swift reference to an underlying GtkAccessible instance. It exposes methods that can operate on this data type through AccessibleProtocol conformance. Use AccessibleRef only as an unowned reference to an existing GtkAccessible instance.

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

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