FrameTimings

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.

Functions

getComplete bool getComplete(): Returns whether @timings are complete.
getFrameCounter long getFrameCounter(): Gets the frame counter value of the GdkFrameClock when this frame was drawn.
getFrameTime long getFrameTime(): Returns the frame time for the frame.
getFrameTimingsStruct GdkFrameTimings* getFrameTimingsStruct(bool transferOwnership): Get the main Gtk struct
getPredictedPresentationTime long getPredictedPresentationTime(): Gets the predicted time at which this frame will be displayed.
getPresentationTime long getPresentationTime(): Reurns the presentation time.
getRefreshInterval long getRefreshInterval(): Gets the natural interval between presentation times for the display that this frame was displayed on.
getStruct void* getStruct(): the main Gtk struct as a void*
ref_ FrameTimings ref_(): Increases the reference count of @timings.
unref void unref(): Decreases the reference count of @timings.
