No, that only happens if you do everything inside one form.

So there is a way to assign different classes to different tabs?
Yes, at least two such ways. One is to design each tab as a separate widget and then create a QTabWidget in manual written code and add those tabs to the widget there. The other is to make each of your pages a custom widget (either through plugins or by promoting the base class to the custom class) and make a form containing QTabWidget and place those custom widget as pages on the form. The first approach is better because you end up with a simpler hierarchy of objects.
