There might be some confusion about Qt the runtime (ie: compiled binaries) and the Qt SDK for development. Last I remember (admitedly, >8 years ago) the Qt SDK certainly was a multigigabyte download. In this case, you need the SDK to develop a UI with Qt, so I think the author's comparison is fair. > Consider Qt Creator IDE which is quite minimalist, without Qt which it requires to run, requires over 200 MB Actual fa…

But either way, 100 vs 200, same order of magnitude keep in mind that Qt Creator comes with a full clang for its C++ code model which is already 40-50 megabytes at least ; no decent C++ IDE can skip that. Regarding the Qt SDK size, what can take gigabytes is installing it for all android & iOS ... ABIs / versions. for a fast SDK i…

I made this comment when someone was talking about using GLFW and IMGUI to make an application with a openGL window and I think it applies here too, because it is easy to overlook the things that you will eventually need that are not trivial to add once you go down the road of using tools made for only very basic UIs. "I would bet that the easiest thing would be FLTK. You can use system colors and make an openGL wind…

Unfortunately, FLTK falls short in at least one important way: it doesn't implement accessibility, e.g. for blind users with screen readers. Godot and immediate-mode GUIs have the same problem. If I'm not mistaken, the most lightweight cross-platform UI toolkit that draws its own widgets (unlike wx or SWT) and implements accessibility is sciter [1]. It's a good thing the antivirus vendors (who seem to be sciter's big…

That's a closed source for pay gui built on html and css.

It probably would not be too difficult to hook into FLTK's label drawing, but this is a general comment about typical small to medium sized guis, originally as a reply to someone needing an internal tool built around an openGL window. Maybe it would be better to make a top level comment and mention that the game engine isn't accessible to blind users.

Interesting Article and also conversation here.

I think the future of interactive immersive VR work environments is looking very strong so using it for GUI apps seems like a good first step.

The author of this article said that he is not a web developer and he has a pro-application perspective. I think he misses the huge opportunity for web properties to also render into Virtual Reality.

Out of curiosity I looked at some of the examples in the Oculus Quest SDK. Basically Android+3D, effective but there is lots of room for improvement.

Are there examples of such advanced GUIs? (links to github)

Why is Hacker News not interested in JavaFX at all? Seriously.

It's not a Godot advertisement. The author is just excited about exploring the possibility of using a game engine for UI development. The point of this article isn't supposed to be a full dive into the nuts and bolts of using of Godot for UI development or anything, just a speculative piece about a novel use for this piece of technology. I doubt the author even knows the answers to a lot of the questions posed. It's…

The "excited about exploring the possibility of using a game engine for UI development" is fine, the "misrepresenting the alternatives" part, especially while ignoring all downsides of Godot, makes it look dodgy and detracts from the piece.

He’s been very clear about what he does and doesn’t know about the alternatives.

Does anyone know if Godot can play a live video stream with graphics drawn on top?

I did an Ask HN [1] about this topic a little while ago. Most relevant comment [2], from gunibert is here: The problem in a framework like GoDot is, that it is meant for Games. A game renders screens in 30/60 fps. A Desktop application like a Gtk application does exactly nothing if you dont interact with the application. If you click a button only the button gets re-rendered. This is more efficient then using somethi…

As mentioned in the article Godot has a low processor usage mode: > If true, the engine optimizes for low processor usage by only refreshing the screen if needed https://docs.godotengine.org/en/stable/classes/class_os.html...

Why would any engine re-render if it's not needed? It will still have benefits even on desktops.

I did a lot of tutorials on my YouTube channel on how to start making GUI applications with Godot. The visual scripting is really bad for now, so I would stick with GDScript (a Python like language) or C#. It is really a great piece of software to make something quick for non-technical people. I really recommend anyone to explore and play with it a bit and I'm sure you'll find a use for this amazing engine.

> visual scripting is really bad for now Are there any visual scripting languages that aren't terrible? The system in unreal works but every time I use it I find myself wanting a text editor (I have spent years learning to program well, be that C++ or shaders, just let me do that!).

If it's general purpose, then I agree that visual languages always seem to be an annoyance. If it's domain-specific, that's another story, since many domains are all about connecting blocks together. The most common use case is audio/video signal processing, where it works well if you're working above a certain level of abstraction.

Why would any software not use an established scripting language like Python or JavaScript? Isn't it just makework and reinventing the wheel (badly)?
