Because QtCreator isn't up to the job compared even with Delphi 1 for Windows 3.x, but sadly the younger generations never got to use it professionally.
Delphi and Visual Basic, were like the Smalltalk/Lisp Machine (I am exaggerating a bit) of the RAD programming generation.
Try to create a database frontend or image manipulation program in QtCreator just with the GUI designer.
The UI part of a database frontend is trivial and the code is very minimal in Qt (but there still code involved, for sure).
An image manipulation program, what does Delphi provide out of the box for this? I would assume that if you have anything non-trivial, you'd have some custom code to write? I mean, they can hardly have built-in components for every possible use case so I don't have to write any code. What am I missing here?
