FrameTimings

open class FrameTimings : FrameTimingsProtocol

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

A GdkFrameTimings object holds timing information for a single frame of the application’s displays. To retrieve GdkFrameTimings objects, use gdk_frame_clock_get_timings() or gdk_frame_clock_get_current_timings(). The information in GdkFrameTimings is useful for precise synchronization of video with the event or audio streams, and for measuring quality metrics for the application’s display, such as latency and jitter.

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

    For type-safe access, use the generated, typed pointer frame_timings_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 FrameTimings instance.

    Declaration

    Swift

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

    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 FrameTimings instance.

    Declaration

    Swift

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

    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 FrameTimings instance.

    Declaration

    Swift

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

    Parameters

    op

    gpointer to the underlying object

  • 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 FrameTimings instance.

    Declaration

    Swift

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

    Parameters

    op
