Redraw

RedrawAtFixedRate renders the current view again and again at the given rate, as long as the view is shown. Use it for views which display a value that changes over time without a state change, like a clock or live measurements. It returns the given view unchanged.

func clock(wnd core.Window) core.View {
	return RedrawAtFixedRate(wnd, time.Second,
		Text(time.Now().Format(time.TimeOnly)),
	)
}

Functions

A rate faster than the frame rate of the application has no visible effect. Each redraw renders the whole view, so keep the rate as low as possible.
