I don't know if they've changed their approach over the past year, but the last time I looked at Qt demos for the web, I was solidly unimpressed. At the time, they were making almost all of the same mistakes that Flutter is, and the devs I talked to seemed to be of the opinion that those problems wouldn't be fixed until browsers started adding brand new capabilities specifically for them. Looking now at the demos at https://www.qt.io/qt-examples-for-webassembly, a lot of the same problems are jumping out at me. A complete lack of accessibility features, poor handling of scroll events, large load times, unfocusable fields, lack of keyboard controls, etc... Halfway through playing with their pizza app, the page just froze and stopped responding to any clicks at all. Maybe those demos are outdated? Blazor and Rust are showing a lot of promise here, but from what I know about Qt I'm much less optimistic, because Qt is used to handling everything about rendering itself -- and as Flutter is showing that's just not a good approach to building web GUI frameworks. But (again, purely from what I've seen) trying to layer on a system where Qt is actually interacting with the DOM seems like it would require a somewhat difficult shift in its architecture. Maybe I'm misunderstanding the problem though. |
I found that hard to believe. But, clicking that link and trying the pizza demo... Yikes. It's not exaggerated at all.
