Please allow application to quit when last window is closed

[Noon_Chen]

@Caliguvara

try tell application (path to frontmost application as text) set WindowCount to get (count of windows) end tell if WindowCount is 0 then tell application (path to frontmost application as text) quit end tell end if end try

You can create an applescript widget in Global with the code above, it'll run in any app, maybe you need to add if - end if block to exclude some apps, such as BTT...

[Caliguvara]

This is one of the typical examples of an app that should run w/o any open window xD Totally forgot about that one, you're right!

[Noon_Chen]

Hi DrewVV,

For simplicity, I'll give a complete walkthru

1. Don't choose a specific app, instead, using conditional group so that you can specify the apps you want:
   
2. Specify the apps like the following:
   
   
3. Create an applescript widget with no assigned actions, no names, no icons, so that it will be invisible on touch bar but still running if the specified apps are at the top, then paste the code:
   
   

tell application (get path to frontmost application as text)
    if (count windows) = 0 then quit
end tell

4. Finished

Please note: if you've set to hide BTT touch bar for this app, or you want to use applications' origin touch bar layout, this will not work, because the code above doesn't even run. But there is a workaround, which is using launchd.

@Noon_Chen did a quite good job here, but it presumes that you have a MacBook Pro with Touch Bar (I think? Or does BTT display Touch Bar settings even on Devices without?). Here is how to achieve it without using the Touch Bar. Stepp 1 and two are the same, then:

3. Go to Named & Other Triggers

4. Create a New Trigger that activates if a specific Conditional Activation Group is activated.
   

   
   
   Don't forget to chose the CAG!
   
   

5. Add an action "Run Apple Script (async in background), and paste the script

    tell application (get path to frontmost application as text)
    	if (count windows) = 0 then quit
    end tell
    repeat until application (get path to frontmost application as text) is not "ABC" or "BCA" or "CBA"
    end repeat
   

Replace ABC, BCA and CBA with your apps, and it should work - didn't give it a field test though

Final Trigger should look like this:

[Noon_Chen]

Ha! Never noticed a trigger can be activated by CAG's status, you're right~

[Caliguvara]

Yupp. CAGs are System wide, not just Touch Bar related

[Caliguvara]

Another option, depending on how many apps you want to "treat" that way: make an App specific section (button left corner), and make ⌘W and the red button inside that application make run this script:

tell application "System Events"
	keystroke "w" using command down
end tell

delay 0.5

try
	tell application (get path to frontmost application as text)
		set WindowCount to get (count of windows)
	end tell
end try

if WindowCount is 0 then
	tell application (get path to frontmost application as text)
		quit
	end tell
end if

Here is how it should look like in BTT preferences:

Thank you, @Caliguvara. I tried various methods, including most suggestions on this discussion thread. The last one you suggested worked!

Some background for others: I need to close Safari when its last window closes, otherwise Safari is in a confused state with regard to the private browsing mode. Since it's only Safari, the second part of the script can be simplified to:

tell application "Safari"
	if (count windows) = 0 then quit
end tell

Let me hijack this thread as I want to achieve something similar:

For any application:
(1) Click on red x window button: Closes the window, and quits the app if it’s the last window. Ideally shows a “do you want to save/are you sure you want to close” dialogue before.

(2) Upon pressing cmd+F4 doing the same thing.

I am currently mapping cmd+F4 to the close window command using Karabiner, but it keeps the app running even after the last window was closed.

[hu_hao]

I tried this, but visual studio code, and calendar, note(mac os native app) did not work

and some other problem, If I open TextEdit, and write something, command + w,then prompt a close window"Do you want to keep", If I click "delete", the textEdit still alive

@Caliguvara Is there any way to fix this?

[jnb]

First of all, thanks everybody for this amazing input!

But I ran into a couple problems (with Monterey 12.6).
With a couple Apps in various situations I got not one window as a result, but two.
I was only seeing one though
In a couple Apps like Maps, Notes etc. it did not work at all.

I came up with a solution I want to share for everybody who wants to achieve this behavior.
For the time being it works incredibly well!

Cheers

tell application "System Events"
    set activeProcesses to first process where it is frontmost
	
    repeat with theProcess in activeProcesses
        if not background only of theProcess then
		
            tell theProcess
                set processName to name
                set theWindows to windows
            end tell
			
            set windowsCount to count of theWindows
        end if
    end repeat
end tell

if windowsCount is less than or equal to 1 then
	tell application (get path to frontmost application as text)
		quit
	end tell
else
	tell application "System Events"
		keystroke "w" using command down
	end tell
end if

Only time it does not work is, when the App is not the frontmost and I click the red button.

Is it possible to get the process of the app, where I clicked the red button, instead of going for the frontmost window?

[hu_hao]

When use Chrome or vscode, I want to quit only after all tabs closed,

hi, how can I exclude some apps in this apple script?

[jnb]

That should be done easy by using a conditional activation group in BTT.
The (+)-Button on the bottom left.

Then you edit the conditions and add a filter with 'App name' is not 'Google Chrome'

[hu_hao]

Hi, when I'm using TextEdit.app, a native in macOS, if write sth in TextEdit,press command + w ， there will be a prompt for the file name, then the prompt will lag and block due to this script, how to resolve this? @jnb

[jnb]

Hi @hu_hao

I don't know your script anymore. Because i changed it quite a lot till know.
But I don't have this problem. So just update with the latest preset I shared here:

Red Button of the last window quits the Application

Description of what you are sharing Opt-in for Apps! Only works for Apps you choose and add to the Conditional List. See How-to for more information. . What the preset is for: If there is only one window left, the App will quit, when the red button of the window is clicked. . How it works: If you want to add an Application, which should quit with the last open window, you have to do the following steps. Click on the Named Trigger 'Close that App'. Click in the right panel on the butt…

and you should be fine.

I also extended the script to work better with different kind of Settings-Windows of different apps, which did not close as long as BTT was running with this preset.

But keep in mind, that you kind of backup the list of apps.

Hope that helps.

Cheers!

Ps. It even works for apps, that are not front-most

[Meave]

Using this method led to the following bug (Reported here). What is your advice?

Describe the bug
Red Window Button does not properly after defining Automations & Named & Other Triggers:

1. Red Window Button does not work at all after quitting BetterTouchTool (e.g., BTT crashes and closed automatically)
2. Clicking on Red Window Button in an app, randomly closes other apps' windows!
3. Clicking on Red Window Button in web browsers' private/incognito windows closes tabs instead windows!
4. Clicking on Red Window Button in Microsoft Edge shows a menu instead of closing the window!

Screenshots
Clicking on Red Window Button in the Activity Monitor app closes Firefox! (Note: Activity Monitor is the active window):

Clicking on Red Window Button in Microsoft Edge shows a menu instead of closing the window:

Device information:

• Type of Mac: MacBook Air M1
• macOS version: 12.6.3 (21G419)
• BetterTouchTool version: 4.023 (2240)

Additional information:
The following Apple Script is defined to run when clicking on Red Window Button based on this topic:

tell application "System Events"
    set activeProcesses to first process where it is frontmost
	
    repeat with theProcess in activeProcesses
        if not background only of theProcess then
		
            tell theProcess
                set processName to name
                set theWindows to windows
            end tell
			
            set windowsCount to count of theWindows
        end if
    end repeat
end tell

if windowsCount is less than or equal to 1 then
	tell application (get path to frontmost application as text)
		quit
	end tell
else
	tell application "System Events"
		keystroke "w" using command down
	end tell
end if

Hi Meave, as far as I can tell from your screenshots you did not install the script as I described in the first place.

The script does not work when you just put the Applescript on the Leftclick-Red-Button-Action.

My LeftclickBA looks like this:

So first thing the script needs is, that it will be activated. This makes sure that this window is the frontmost window. Otherwise it won't work and closes the other apps, that are actually active

[jnb]

I just realized that this is a different thread than I expected.
I had my problems with this script too. So I developed a preset which got rid of most of the quirks (not all though).

Try to install the preset and see if it works better for you:

Red Button of the last window quits the Application

Description of what you are sharing Opt-in for Apps! Only works for Apps you choose and add to the Conditional List. See How-to for more information. . What the preset is for: If there is only one window left, the App will quit, when the red button of the window is clicked. . How it works: If you want to add an Application, which should quit with the last open window, you have to do the following steps. Click on the Named Trigger 'Close that App'. Click in the right panel on the butt…

One example for the quirks are, that some settings windows from Menubar-Apps are never registered as frontmost and do not close with the red button. For example 'AlDente' in my case. So whenever I need to change anything in this app I have to deactivate/activate BTT.

[jnb]

Another thing.
You can always open the Hovered/Focused UI Element Viewer to see what windows is registered as frontmost/hovered.
You get there by clicking on your trigger > Advanced Conditions (right panel) > Hovered/Focused UI Element Viewer.

Cheers
