Sorry for PR without opening an issue again...

Also I want to clarify why am I contributing to Bottles all of a sudden.
I currently working on my own GTK4/Adwaita application, and I look at Bottles code as an example a lot, and sometimes spotting some bugs like this
I don't use any of assets of course, and don't straight copy-paste any code, so I hope you're fine with that

[TheEvilSkeleton]

That's fine. To be fair, your MRs have been really useful so far and I really like them. Feel free to join our Discord server if you want some help with development :)

[RozeFound]

Hmm, I'll look into it

[RozeFound]

How does it look now?

[TheEvilSkeleton]

Honestly, I really like how "No Thumbnail" looks, but we'll have to discuss its looks in #2458

The rest looks great 👌

Well, that was not me who added that, it was in code just disabled

[TheEvilSkeleton]

Oh, 😅

[TheEvilSkeleton]

Hmm... it looks like it gets "stuck" when you remove an entry, but centers when you restart the app:

Screencast.from.2023-03-24.21-51-06.webm

Can you make it centered all the time?

[RozeFound]

That's weird...

[TheEvilSkeleton]

Yeah :/

[RozeFound]

oh. self.update() not called on entry removal, that's why

[RozeFound]

Sorry to make you test every little change... But this time I hope it'll work

[TheEvilSkeleton]

Don't worry about it. I do QA a lot, so I'm used to it :)

[TheEvilSkeleton]

I just tested it, and it looks good to me. I'll let it sit for a bit and wait until we figure out #2458... unless it takes a really long time

[TheEvilSkeleton]

Looks like there won't be any response anytime soon. I'll just merge it. Thank you once again!

@RozeFound I just noticed this in the original comment. If you want to test next time, click on the Details button in the "Build Flatpak" field at the bottom of the MR. It should look like this:

You won't see this button in this MR, as I just merged it. You can open another MR and try it there. Afterwards, press "Summary", and then click "bottles-x86_64" under "Artifacts". It should download a zip archive. Then, unzip it, and finally run flatpak install bottles.flatpak to install it. I highly recommend backing up ~/.var/app/com.usebottles.bottles before testing experimental builds.

When you're done testing, you can run flatpak remove --no-related com.usebottles.bottles//master to uninstall the experimental build.
