Component

open class Component : ComponentProtocol

AtkComponent should be implemented by most if not all UI elements with an actual on-screen presence, i.e. components which can be said to have a screen-coordinate bounding box. Virtually all widgets will need to have AtkComponent implementations provided for their corresponding AtkObject class. In short, only UI elements which are not GUI elements will omit this ATK interface.

A possible exception might be textual information with a transparent background, in which case text glyph bounding box information is provided by AtkText.

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

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

    For type-safe access, use the generated, typed pointer component_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 Component instance.

    Declaration

    Swift

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

    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 Component instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 Component 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 Component instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 Component instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements ComponentProtocol AtkComponent does not allow reference counting.

    Declaration

    Swift

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

    Parameters

    other

    an instance of a related type that implements ComponentProtocol
