Switch

ui.Switch creates a switch turning a *bool on and off, for a setting that applies at once: a click turns it over, as does Space while it has the keyboard focus, and its knob slides across. Changed reports a click.

ui.Row(c).Gap(12).Children(func() {
	ui.Text(c, "Wi-Fi").Grow(1)
	ui.Switch(c, &app.wifi).Label("Wi-Fi")
})

A switch shows no text of its own: give it a Label for assistive technology, or put it in a field, whose label names it and toggles it when clicked:

ui.Form(c, func() {
	ui.Field(c, "Sound", func() { ui.Switch(c, &app.sound) })
})

For a choice that applies when a form is saved, use a check box.

Without a look

ui.SwitchBase is a switch without a look, which you draw from the value: see custom widgets.

Accessibility

Assistive technology sees a switch, on or off, named by its Label or its field.
