Sets the delay, in seconds, between animation steps for an indeterminate progress indicator.
- macOS 10.0–10.6Deprecated
The number of seconds between animation steps. By default, the animation delay is set to 1/12 of a second (5.0/60.0). Setting the delay to a double value larger than 5.0/60.0 slows the animation, while setting the delay to a smaller value speeds it up. A determinate progress indicator does not use the animation delay value.
