How to trap AutoHotkey to the window I want

[roysubs]

I see that a Chocolatey package for GhostScript is using the following AutoHotkey to automate their installation.

This seems to trap AutoHotkey so that it only sends keypresses into the correct Window.

What part of this code is controlling that please? Is it the "ControlSend"? I've never really figured out how to trap AutoHotkey into exactly the right place I want it to send keypresses.

Code: Select all

#Requires AutoHotkey v2.0
#NoTrayIcon
#SingleInstance Force
#Warn
SetTitleMatchMode "RegEx"
exe_re := "gs.+.exe"

If WinWait("ahk_exe " exe_re, "Next >", 20)
   ControlSend "{ENTER}",, "ahk_exe " exe_re
Else
   exit 1

If WinWait("ahk_exe " exe_re, "I Agree", 20)
   ControlSend "{ENTER}",, "ahk_exe " exe_re
Else
   exit 1

If WinWait("ahk_exe " exe_re, "Install", 20)
   ControlSend "{ENTER}",, "ahk_exe " exe_re
Else
   exit 1

If WinWait("ahk_exe " exe_re, "Finish", 20)
   ControlSend "{ENTER}",, "ahk_exe " exe_re
Else
   exit 1

if WinWait("ahk_exe " exe_re, "OK", 20)
   ControlSend "{ENTER}",, "ahk_exe " exe_re
Else
   exit 1

ExitApp

Yes, ControlSend sends keystrokes to a particular window. The very first line on its documentation page clearly states that.
