  • Last time I've looked at Relm4 it was in the middle of global refactoring that required changes to all codebases. Is it stable(-r) now?

    Also what is this cross-platform you speak of, if we're talking about Gtk4? Compiling glib on Windows doesn't sound very cross-platform to me. Heck, Gtk4 doesn't sound very cross-platform if we're thinking about anything that's not Gnome.

  • > Built on GTK, Relm4 runs on bare metal with no additional runtime in between.

    So, not native in the sense of using or even resembling the native UI toolkit.

  • Interesting - If you're after cross platform Flutter/Dart seems a more cross platform solution (mobile, desktop and web), or Delphi/Lazarus without the web.

  • How does it help build idiomatic cross-platform apps? A cross-platform app can't really be idiomatic by definition, since different platforms have different idioms, both in terms of APIs and UI. If the project somehow solves this, I'd expect that to be explained. I couldn't find such an explanation on the website.

  • Why no examples of how "beautiful" this library is?

  • I used plain gtk-rs for my last project and there is definitely some friction between rust and the gobject system. I think for my next project I will give relm4 a try. Apparently you can always drop back to gtk-rs if needed.

  • This is Gnome/GTK, not cross-platform like I would have expected. A Linux-first approach. I’m happy that this is the world we’re in now but expect it still to be royal pain to get a build running on Windows. Huge congrats to everyone involved if not!

  • Reading the documentation, I just notice lots of familiarity with my own solution using haskell and gi-gtk4. I think that anybody that read https://bichanna.github.io/posts/tea-time/ will get the same ideas. This basically boils down to:

    1. Use a native widget system such as GTK (I evaluated Qt too)

    2. Wrap widgets into a component datatype that is aware on how to update the widget when the props/model changes.

    3. Define a dispatch closure that is passed to widget that accepts messages. Actions on the widgets should use this instead of mutating a reference.

    4. That dispatch closure is component aware and it will call the update function on all the widgets.

    There are some extra complications for long running computations but the model is a good base to build on. I wish the best to the relm team, most likely I will use them when programminmg in rust.
