Detailed Description

Snap-animation policy gate — decides if a transition merits animation and builds a MotionSpec<QRectF> for AnimatedValue::start().

Function Documentation

createSnapSpec()

PHOSPHORANIMATION_EXPORT std::optional< MotionSpec< QRectF > > PhosphorAnimation::SnapPolicy::createSnapSpec	(	const QRectF &	oldFrame,
		const QRectF &	newFrame,
		const SnapParams &	params,
		IMotionClock *	clock
	)

Returns nullopt when clock is null, newFrame is degenerate, or the move is below threshold with no size change.

Otherwise returns a MotionSpec with no callbacks (caller wires those).
