Changing Tray Icon when script is paused - scripting

Question

I have googled a bit, but I'm not able to find how to do this. I need custom icon when script is paused/suspended. I know how to change it on key press, but I need same functionality like when you suspend it with right mouse click in System Tray. When you do that standard AHK icon will have red background, if paused and it will change letter to "S" if suspended. My script needs to change to custom icon when it's paused/suspended, when you right-click on the icon in Tray and suspend it. No key press activation needed, eventually script need to detect when I pause/resume it and change to different custom icons.

Answer 1

You can change the tray icon at any time, so you can do so before you pause and return it back to normal when you unpause the script like so:
; start of script
Menu, Tray, Icon, normal.ico
; pause icon
Menu, Tray, Icon, paused.ico
Pause, On
; return to normal
Menu, Tray, Icon, normal.ico
Pause, Off
See https://www.autohotkey.com/docs/commands/Menu.htm#Icon
Edit: make your own tray menu, very basic code you need to expand to turn it on/off, simply to illustrate
Menu, Tray, Icon, normal.ico, , 1
Menu, tray, NoStandard ; removes edit, pause, reload etc
; other menu options
Menu, tray, Add, &Suspend Hotkeys , MenuHandler
Menu, tray, Icon,&Suspend Hotkeys , %A_AhkPath%, 3 ; default suspend icon
Menu, tray, Add, &Pause Script , MenuHandler
Menu, tray, Icon,&Pause Script , %A_AhkPath%, 4 ; default pause icon
;
MenuHandler:
;
If (A_ThisMenuItem = "&Pause Script")
{
Menu, Tray, Icon, paused.ico
Pause
Return
}
