Cursor Manager

The CursorManager controls the exact visual blink interval algorithm without relying on UI-layer components (like React useEffect).

Constructor

new CursorManager(onTick: () => void)

Accepts a single onTick callback, which immediately instructs the overlay renderer proxy to redraw the page canvas when the visibility shifts.

Properties

BLINK_INTERVAL_MS

static readonly BLINK_INTERVAL_MS = 530;

The physical loop timer in milliseconds (530ms accurately simulates native Windows/Chrome styling).

isVisible

get isVisible(): boolean

Flag indicating whether the paint cycle should render a solid block or clear the pixels natively.

Methods

start()

start(): void

Begins the setInterval synchronization phase. Overrides any pre-existing timers safely.

stop()

stop(): void

Clears the active timer. Triggered organically when the Editor is blurred/deselected.

reset()

reset(): void

Fires on every keystroke. Forces isVisible = true and perfectly restarts the 530ms clock. This guarantees that typing rapidly never encounters an "invisible cursor" frame cycle, perfectly mimicking native browser input behavior.

resetSilent()

resetSilent(): void

Identical to reset(), but suppresses the onTick UI repaint. Used specifically when the Engine anticipates an immediate Layout Flush natively (preventing double-render flash crashes).
