While you can create one on your own, any lib that doesn't have a tree widget isn't ready for primetime IMO. Obviously others may have a different opinion. Also, I don't believe there is any way to embed a webview at this point which is often necessary to embed things like charts or other widgets you don't want to create on your own.
GUI toolkits are like MS Word... as the saying goes, everybody only uses 10% but everyone uses a different 10%. This is one of the major things that makes it so hard to have a truly world-class widget set. Making "a" widget set is easy. Making a great one is staggeringly enormous.
I agree - which is why it seems like a better idea to either write bindings to an existing one or use something like Tauri/flutter/etc. It will be VERY hard to both 1) create an adequate UI paradigm in Rust -AND- 2) have a complete widget set large enough to create any business app
Also, tableview/datagrid, complete with support for sorting and reordering items and columns.
It’s shockingly difficult to find newer UI frameworks with this, even though it’s one of the most important desktop UI widgets for a lot of use cases. Win32, Cocoa, GTK, and Qt Widgets have it though, and that’s part of why those toolkits continue to get used.
