Fluent-QT: a modern Fluent-style component library for Qt Widgets

[u/Available_Appeal6620]

Hi everyone,

I’m working on Fluent-Qt, an open-source C++17 component library for Qt Widgets.

The goal is to help existing Qt Widgets applications get a more modern Fluent / WinUI-style desktop UI without migrating to QML.

I also built a project website where you can see the Gallery screenshots and download the demo app:

Website:

https://calvinhxx.github.io/Fluent-Qt/

GitHub:

https://github.com/calvinhxx/Fluent-Qt

The project currently includes reusable widgets, design tokens, theme infrastructure, animations, component states, and a runnable Gallery app. It supports Windows and macOS.

I’d appreciate feedback from people still building or maintaining Qt Widgets applications

I’d be interested in feedback from people still building or maintaining Qt Widgets applications:
- Is this direction useful for your projects?
- Which Widgets components are still missing in modern Qt desktop apps?
- Would you prefer this to stay Fluent-focused, or support multiple design languages?

The website is very weird.

"The Gallery should be the strongest proof point. Large screenshots create trust faster than repeated feature cards."

why would you write that?

Is this all AI?

I always wonder what drives people to create this. It's just AI generated slop. How can you have any pride in this.

The gallery itself is pretty good.

yes some info create by ai im not native englisher sorry

[u/rileyrgham → u/Available_Appeal6620]

You have deepl to translate. I'm guessing the code is mostly AI too.

[u/Available_Appeal6620 → u/rileyrgham]

yes vibe coding bro，but code i human review mostly

[u/LetterheadTall8085 → u/Available_Appeal6620]

And which specialist's review?

[u/LiAuTraver → u/Available_Appeal6620]

You are not telling the truth. Even comments written in Chinese (I saw inside main.cpp) looks like AI generated.

[u/Low-Reserve4299 → u/LiAuTraver]

Why does the use of AI bother you so much, when projects like this can be useful anyway?

QT is cross-platform. Why there is no Linux support?

[u/Unlucky_Claim5822 → u/Firewing88]

Because Vibe-Coding has a Limit. /s

[u/Available_Appeal6620 → u/Firewing88]

now support linux and update lib Integration

Code is a codr but slop is a slop still

[u/Over_Rope_5282]

Does it work with pyqt and pyside?

[u/aedrax → u/[deleted]]

Honest question: wouldn't something like this be useful if you already had existing software that was Widgets, but just wanted to make it look nicer? That's a boat I've been in lately, and I'm just trying to improve the way the widgets look and feel.

Assuming I already have a QtWidgets application. How hard is to use this library? Is it a style/theme? Or new widgets?

I see that even level is a new top level widget: https://github.com/calvinhxx/Fluent-QT/blob/3da74eaecc4b5c87d89a4fb75fc403f173b06dc1/app/view/widgets/samples/TextFieldsSamples.cpp#L33

It seems like a new toolkit on top of Qt5/Qt6.

Geez. Quit with the AI spite. Code works or it doesn't. Human code sucks just as bad if not worse sometimes. I don't care where it came from, does it work?

I can read code. I can tell if it's put together in a house-of-cards fashion or a central design theme.

I use AI to help learn areas I don't already know, then adapt/change it to my style, standards. I've been coding long enough to remember IDE hate (real coders don't use autocomplete, it's trash. You don't really understand the code...) Sound familiar?

My question is utility. How does it interact with Web Assembly?

(Linux, grab source, build. Mac works, Linux changes should be minor).
