Starting with Java and .NET, I'm used to declaratively associating domain objects with user interface controls. It seems that in fact there is no established idomatic way to bidirectionally connect (not Qt) domain objects and Qt objects. The implementation of the signal slot mechanism in domain objects will obviously pollute the model of the main domain and introduce unwanted dependencies.
I know that database binding is available, but this is not my use case.
What is the practice of large Qt projects in this regard?
