How to retrieve the script 'mainwindow' title?

[c7aesa7r]

i have some scripts running and they contains more than one gui, one of these guis is use to identify the script, the gui title is dynamic being changed according to some settings

atm this is how im searching for the 'main' GUI:

Code: Select all

WinGet, Id, List, ahk_pid %Pid%

Loop, %Id%
{
	Id := Id%A_Index%
	WinGetTitle, Title, ahk_id %Id%
	If (SubStr(Title, 1, 3) = "#0x") {
		;main GUI found
	}
}

i was reading the docs, and found that there's a 'Main Window'
https://www.autohotkey.com/docs/Program.htm#title

is possible to modify/get the title of this specific window? the script itself would modify the title and another different script would read its title

One easy way to do this is to apply a prefix to the title, then you can easily find it and extract the code or whatever is unique about it from the title

Code: Select all

prefix := "UniquePrefix - "
code := "0xFF123456"

gui,show,,% prefix code   ;shows a window the the title UniquePrefix - 0xFF123456

SetTitleMatchMode,1 ;requires the title matching to be at the start

WinGetTitle,title,UniquePrefix  ;onlys gets a window that has this unique prefix

if (RegExMatch(title,prefix "(.*)",code))  ;if a valid window then extract all the string after the prefix
	msgbox % "Found title!`n`n" title "`n`nCode is '" code1  "'"   ;value is stored in code1 variable

exitapp

This method returns only one window title, when you have multiple windows (from different scripts) with the prefix, how to proceed?

Yes, just use WinSetTitle/WinGetTitle as with any other window.

As with any other hidden window, if you don't show the main window first (with something like ListLines), you will need DetectHiddenWindows On.

Keep in mind that if you change the main window's title, #SingleInstance will not work and Reload will not terminate the old instance.

Also, if each script has only one unique instance, you can uniquely identify each script's main window by a combination of the script's full path and ahk_class AutoHotkey.
