nodegui VS Windows UI Library

This looks like it hasn't been maintained in years but there's a modern equivalent in NodeGUI [1] which also has React/Svelte/Vue implementations. Unfortunately it requires a custom build of Node that merges the libuv and Qt6 event loops so YMMV.

It actually inspired me to write my own implementation with Svelte on top of QuickJS and Qt Widgets but the task of wrapping the entire Qt6 API in Rust proved to be intractable once I found out that most methods weren't marked Q_INVOKABLE and thus couldn't be called via reflection (requiring manual wrapping). Providing a `Document.createElement` API that created Qt Widgets with working attributes and event handling worked surprisingly well though!

Hi, so this NodeGui library for building apps with native components is something I really want to get into, but, it does not work for me.. so I am starting this thread to check with yous (I depleted google results) if any one of you have tips or workarounds I can use. I wish to build a desktop app, but I really do not want to bundle a web browser for that purpose and NodeGui seems perfect.

Use NodeGui (or some equivalent tool) for this. Source: https://docs.nodegui.org/ This is needed because this entire project will run natively, by that I mean it will run with no browser, no local host and it no internet connection.

NodeGUI

Let's continue exploring Electron alternatives. This time, NodeGui. NodeGui uses Qt5 instead of Chromium, so we'll be leaving the familiar web development behind, but it tries to not be too far from it, as web development is what everyone knows.

(Disclaimer: My knowledge of Rust very limited, but I have quite a bit of experience with getting Qt/KDE classes to work with other languages.)

You are absolutely right. The effort to be acceptable bindings for Qt would be a tiny fraction of the cost compared to building a whole new Rust native GUI library.

Qt is huge set of libraries with an equally huge API. But there are a lot of shortcuts and smart ways of approaching the problem to get what you want out of Qt for minimum effort.

Bindings like PyQt and even PySide go for the nuclear option of generating bindings for the whole Qt API and trying to match the C++ API in style too. This is an absolutely massive huge task. Also, getting people to contribute to an open source bindings project is hard. Getting people to contribute to a bindings generator is even harder.

NodeGui https://github.com/nodegui/nodegui, Qt bindings for Nodejs, on the other hand takes a very different approach which in one way is low-tech but I think is actually very smart. I'll summerise the differences:

* It focuses on Qt Widgets first. This greatly reduces the amount of work to the parts that people actually need. (BTW, if you just want QML and Rust back-end then Jos van den Oever's work at https://invent.kde.org/sdk/rust-qt-binding-generator has probably got you covered already.)

There is actually a new GUI framework based out of Qt (a C++ GUI framework) that I have found recently : https://docs.nodegui.org/

I wish that was true, but even the new stuff, like their new frameworks, performs poorly while their older frameworks perform really well. That's brand new code, with no legacy codebase to care for.

The reason why I don't recommend Winui is the million bugs it has. See the github issues page. All Microsoft ui stuff sucks currently. But if you use WPF why not FluentWPF

Development for WinAppSdk and WinUI 3 is also very slow and Microsoft seems to not want to push it and invest more developers into it for some reason. They try to improve the framework, is just it's a small team. For example it was a headacke to apply the Mica backgrop and required unmanaged code, they made it simpler and reduced it to a line of code but it took months. I have 2 out of 7 issues fixed on WinAppSdk repository and 0 out of 8 issues fixed in the WinUI 3 repository (some of the older than a year). This are just my issues, there are many other opened by other developers. So yeah, it wasn't fun at all. PoweshellSDK had an issue with the Import-Module command and it wasn't fixed for more than a year and probably won't be ever fixed, but I'm glad I found a workaround, even more clean and more safe, otherwise I couldn't have added the posibility to uninstall and change Store apps.

Compared to UWP or WPF, WinUI 3 is somewhere between 100-200% slower and consumes 7-20 times as much RAM as the old frameworks (for certain operations).
