Sets the delay that will occur after each control-modifying command.
SetControlDelay DelayCommand Example: SetControlDelay 100 Function Example: SetControlDelay(100)
Time in milliseconds. Use -1 for no delay at all and 0 for the smallest possible delay. If unset, the default delay is 20.
A short delay (sleep) is done automatically after every Control function that changes a control. This is done to improve the reliability of scripts because a control sometimes needs a period of "rest" after being changed by one of these functions. The rest period allows it to update itself and respond to the next command that the script may attempt to send to it.
Specifically, SetControlDelay affects the following functions: ControlAddItem, ControlChoose, ControlChooseString, ControlClick, ControlDeleteItem, ControlEditPaste, ControlFindItem, ControlFocus, ControlHide, ControlHideDropDown, ControlMove, ControlSetChecked, ControlSetEnabled, ControlSetTab, ControlSetText, ControlShow, ControlShowDropDown.
ControlSend is not affected; it uses SetKeyDelay.
Although a delay of -1 (no delay at all) is allowed, it is recommended that at least 0 be used, to increase confidence that the script will run correctly even when the CPU is under load.
A delay of 0 internally executes a Sleep(0), which yields the remainder of the script's timeslice to any other process that may need it. If there is none, Sleep(0) will not sleep at all.
If the CPU is slow or under load, or if window animation is enabled, higher delay values may be needed.
The built-in variable A_ControlDelay contains the current setting and can also be assigned a new value instead of calling SetControlDelay.
Every newly launched thread (such as a hotkey, custom menu item, or timed subroutine) starts off fresh with the default setting for this command. That default may be changed by using this command in the auto-execute section (top part of the script).
