FrameTimings

class FrameTimings(pointer: <Error class: unknown class><<Error class: unknown class>>)

A GdkFrameTimings object holds timing information for a single frame of the application’s displays.

To retrieve GdkFrameTimings objects, use method@Gdk.FrameClock.get_timings or method@Gdk.FrameClock.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.
