getCurrentTimings

open fun getCurrentTimings(): FrameTimings?

Gets the frame timings for the current frame.

getFps

open fun getFps(): <Error class: unknown class>

Calculates the current frames-per-second, based on the frame timings of @frame_clock.

getFrameCounter

open fun getFrameCounter(): <Error class: unknown class>

GdkFrameClock maintains a 64-bit counter that increments for each frame drawn.

getFrameTime

open fun getFrameTime(): <Error class: unknown class>

getHistoryStart

open fun getHistoryStart(): <Error class: unknown class>

Returns the frame counter for the oldest frame available in history.

getTimings

open fun getTimings(frameCounter: <Error class: unknown class>): FrameTimings?

Retrieves a GdkFrameTimings object holding timing information for the current frame or a recent frame.

onAfterPaint

fun onAfterPaint(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: () -> Unit): <Error class: unknown class>

This signal ends processing of the frame.

onBeforePaint

fun onBeforePaint(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: () -> Unit): <Error class: unknown class>

Begins processing of the frame.

onFlushEvents

fun onFlushEvents(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: () -> Unit): <Error class: unknown class>

Used to flush pending motion events that are being batched up and compressed together.

onLayout

fun onLayout(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: () -> Unit): <Error class: unknown class>

Emitted as the second step of toolkit and application processing of the frame.

onPaint

fun onPaint(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: () -> Unit): <Error class: unknown class>

Emitted as the third step of toolkit and application processing of the frame.

onResumeEvents

fun onResumeEvents(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: () -> Unit): <Error class: unknown class>

Emitted after processing of the frame is finished.

onUpdate

fun onUpdate(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: () -> Unit): <Error class: unknown class>

Emitted as the first step of toolkit and application processing of the frame.

requestPhase

open fun requestPhase(phase: FrameClockPhase)

Asks the frame clock to run a particular phase.
