Description

When I open Processing (let's say the default theme is theme A), change to a different theme (let's call this theme B), close Processing and open it again, theme A shows instead of theme B.

Expected Behavior

Theme B should appear after relaunch instead of theme A.

Current Behavior

Theme A appears after relaunch instead of theme B.

Steps to Reproduce

1. Open Processing
2. Change theme
3. Close Processing
4. Open Processing again

Your Environment

• Processing version: 4.0.1
• Operating System and OS version: Windows 10 21H2
• Other information:

UPDATE

I'm so stupid lmao. Steps to fix:

1. Open Tools -> Theme Selector
   
2. Choose your theme (I like this one)
   
3. The theme should apply.
   
4. Click on "-> Save theme.txt to sketchbook for editing"
   
5. Bada-bing-bada-boom, you can relaunch Processing while keeping in mind that your theme won't be lost!

Not stupid at all—that should be working without you having to save the theme file explicitly like that.

Is there something that might be resetting your preferences file when you restart? i.e. is this a public or school lab machine?

Comment from @Matto58 in #590:

its my own computer that i had for years now that i use for my personal stuff

Apologies, I thought I'd unlocked this one when I reopened it.

If you remove the theme.txt file and restart, are you able to select a different theme and have it stick? In past releases, the only way to set the theme was to write that file, but changes were made to no longer require it. So I'm just trying to figure out what might be going wrong. (If you're using a beta instead of 4.0.1, that would do it too…)

FYI: I am using a non-beta version

Here's before I delete it:

Here's after I delete and restart:

Here's after I set a new theme without explicitely saving theme.txt:

And here's after a restart:

If you change any other settings, do they remain set after a restart? (i.e. change the font size in Preferences; what happens?)

So to answer your question: Nope.

Just checking - is this being worked on? Sorry if I'm being a little rude!

At the moment I don't have anything to work on—I can't reproduce the problem. The theme is stored in the preferences file, so I was asking about changing other preferences to see if it was a problem there. Since those preferences are working, I'm stumped because I can't find another machine that has the issue. I've tried 3 that I use for testing and all of them are working fine.

If anyone else runs into this problem and can shed some light, please help—I'd obviously like to fix it but there's nothing to fix at the moment.

One more thing to check: after you change the theme, check preferences.txt (the location for the file is listed in the Preferences window) for the line that starts with theme=. It should read something like theme=Minerals/kyanite.txt (though that's the default, so hopefully it reads something different).

Next, look for a folder named theme in your Processing installation, and make sure the specified file is still there. For instance, for Minerals/kyanite.txt that means that there's a folder called Minerals inside theme, and that inside Minerals is a file named kyanite.txt.

I can have the exact same problem.

I have found the cause of the problem on my machine: Preferences are not saved at all when closing the window with the close button on the right of the window title bar or by using Alt-F4, however they are correctly saved when closing with Menu bar -> File -> Quit or Ctrl-Q. I have verified that with preferences.txt.
I think the save method of the Preferences is not executed in the first situation.

I am using:

• Processing version: 4.0.1
• Operating System and OS version: Windows 10 22H2

Thanks, that's helpful… With that, I can at least have it explicitly save the preferences each time there's a theme change. It's overkill but better than it being sometimes broken.

That fix is in the source, so it'll be in the next release (4.0.3 or 4.1) when available. Or if you'd like to give it a try, see about building the source and let me know.

Thanks for the fix, I think this will work for a theme change (I didn't manage to test the fix), but I want to point out that this will not solve the problem for font size (and other preferences).

Preferences not saving is a totally new/separate issue that I'd not heard of before. Can you file an issue for it? For the original poster here, other preferences are working fine, this is only about the theme itself not saving when changed.

I'd like to correct you: in this comment, it says nope, saving other preferences don't work, as a reply to this comment
