BusyDelay changes the amount of time that must elapse between accessing user events before MacApp displays the busy cursor. BusyDelay calls BusyReset to examine the state flags changeToWatch and inControl in the cursor information record.
The newDelay parameter is the new value of the delay time in ticks; a value less than or equal to 0 does not change the delay time.
BusyDelay is called by the global routine BusyInstall when it installs the busy-cursor mechanism. You can call BusyDelay when you want to change the delay time that elapses before the watch cursor is displayed.
