Programming is manipulating cryptic colorful text. That sadly seems to be the definition we are stuck with. You start to get into anything that involves drag & drop, you are inviting other programmers to assume you are not good enough with cryptic text.
Its just a stupid psychological thing. And I think it holds back software engineering.
Having used QtCreator to build a medium sized GUI, it was a pain. The XML it produces is too unwieldy to manually edit, so that's out (though I did edit it a few times to overcome bugs in QtCreator)
The QtCreator GUI itself is very robust but if you want to do something that's off the beaten path good luck, you're gonna be doing a lot of trial/error clicking and iteration. There were times when everything was "right" in QtCreator, and the result didn't work...
I would much prefer to use something like QtDeclarative if I do it again. It's easier to tell the computer exactly what I want, and then get exactly what I want, when the language for expressing what I want is concise and small.
It's more that drag and drop isn't really good for much when it comes to programming. You can build GUIs with it and some extremely simple tasks like email joruneys, but for anything else visual programming has proven to be pretty poor.
Analogously, the tools already available to computer users are tools that could harm the user if used improperly. To not empower users because they might harm themselves isn't progressive, it's paternalistic.
Since then, I've seen .NET within Visual Studio almost get to the same quality we had with Delphi in 1995, but still way off.
Now that everything's a web app wrapped in something like Electron, it should be so much easier to have tooling like this, but yet we're all still building hugely complicated HTML rendering pipelines for something that was a solved problem a couple of decades ago.
