> 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?

The eco-system of companies selling components for every possible use case.

Most VB/Delphi shops would get early licenses from such companies. DevExpress is a surviving company from those days.

So you had a huge toolbox full with components for the majority of enterprise most common use cases.

As far as I am aware, there aren't any company selling components for Qt.

There are, but they're few and far between and certainly not as diverse as what you've described.
