requestAnimationTick
requestAnimationTick(
owner,ms,paintOnly?):void
Defined in: src/anim/animation.ts:157
Ask for a re-render roughly ms from now, on a macrotask. Animated widgets
must use this instead of calling App.queueRender() from render() — that
queues a microtask, and a render that always re-queues itself forms an
unbroken microtask chain that starves timers and I/O.
paintOnly marks an animation that changes only appearance, never geometry
(a breathing focus ring, an attention glow, a spinner glyph, a color tween).
Such ticks request a Repaintable.queueRepaint, which reuses the prior
layout instead of relaying out the whole tree every frame — the difference
between a focused screen idling cheaply and re-measuring everything ~60×/s.
Leave it false for scalar tweens that may drive size/scroll.
The re-render is dispatched on the owner’s own App (reached via
owner.app), so multiple live apps — tests, the web backend — each drive
their own tree. A detached owner (no app) is a no-op: there’s nothing to
paint.
