Text

open class Text : TextProtocol

AtkText should be implemented by AtkObjects on behalf of widgets that have text content which is either attributed or otherwise non-trivial. AtkObjects whose text content is simple, unattributed, and very brief may expose that content via atk_object_get_name instead; however if the text is editable, multi-line, typically longer than three or four words, attributed, selectable, or if the object already uses the ‘name’ ATK property for other information, the AtkText interface should be used to expose the text content. In the case of editable text content, AtkEditableText (a subtype of the AtkText interface) should be implemented instead.

AtkText provides not only traversal facilities and change notification for text content, but also caret tracking and glyph bounding box calculations. Note that the text strings are exposed as UTF-8, and are therefore potentially multi-byte, and caret-to-byte offset mapping makes no assumptions about the character length; also bounding box glyph-to-offset mapping may be complex for languages which use ligatures.

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

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

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

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

    Declaration

    Swift

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

    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 Text instance.

    Declaration

    Swift

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

    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 Text 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 Text 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 Text instance.

    Declaration

    Swift

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

    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 Text instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements TextProtocol AtkText does not allow reference counting.

    Declaration

    Swift

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

    Parameters

    other

    an instance of a related type that implements TextProtocol
