Detailed Description

Wraps GfxContext's shared wall-timer (clock #2, the default).

One TimerClock == one HighResolutionTimer acquired from a score::Timers pool at a given frequency, shared (coalesced) among every output rendering at that rate — mirroring the old GfxContext::m_manualTimers entry. The per-output fan-out (render() for each output that canRender()) lives in the tick closure that GfxContext hands to start(), exactly as the old on_manual_timer did.

Constructor & Destructor Documentation

TimerClock()

score::gfx::TimerClock::TimerClock	(	score::Timers &	timers,
		QObject *	owner,
		double	frequencyHz
	)

Parameters

timers	the (per-GfxContext) timer pool to acquire from
owner	QObject used as the queued-connection receiver context, so the tick runs on that object's thread (score's render thread) — identical to the old connect(timer, ..., this).
frequencyHz	the shared timer frequency (1000 / manualRenderingRate)

Member Function Documentation

kind()

Kind score::gfx::TimerClock::kind ( ) const

inlineoverridevirtualnoexcept

Implements score::gfx::RenderClock.

start()

void score::gfx::TimerClock::start ( std::function< void()>  tick )

overridevirtual

Begin delivering ticks.

tick is invoked once per render tick, on the render thread. The clock owns the tick source (timer, vsync registration, or hardware wait loop).

Implements score::gfx::RenderClock.

stop()

void score::gfx::TimerClock::stop ( )

overridevirtual

Stop delivering ticks and release the underlying tick source.

Implements score::gfx::RenderClock.
