GI.Gdk.Structs.FrameTimings

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.
