I’ve used Godot, which works great but I’m wondering if there are other ways.
Does anyone have experience using Qt with Rust and Qt Designer?
Are there any other drag and drop options that you think are viable?
Not sure what you are trying to do but drag&drop UI design is not as popular as it was back in the 90s mainly because modern applications and games often need to run on a variety of window and screen sizes so they need to be more dynamic than the graphical approach to building them can handle both in terms of sizes and aspect ratios and also in terms of omitting and replacing UI elements on smaller screens.
It’s not immediately clear what it is you’re trying to achieve, but if you were able to solve it in Godot then you can probably solve it with Bevy it’s an ECS based game engine for Rust.
I’ve been incredibly impressed with it so far, and they’ve got a rapid rate of development so it’s improving fast.
The recent v0.15 release integrated support for picking that includes specific events for drag and drop:

You can find some UI examples here, none specifically show drag and drop as far as I can see. There are separately some examples of picking that you might want to look at
