What's the concept I should use to build "hierarchical" GUIs in Qt?

I've done a lot of WPF and am now, for the first time, trying to get a grasp of Qt, so far fairly successful.

However, in WPF, I'm used to encapsulate self-enclosed开发者_运维知识库 parts of GUIs in User Controls so that I can then easily re-use them across dialogs or rearrange an entire block without having to touch every single element. If, for example, I was building a main window that would show information about a hospital, about the area it is in and about its manager, I would encapsulate each of the three blocks in a User Control and my main window would just contain three instances of those controls.

With Qt, I was as yet unable to identify the concept I should use for this type of encapsulation. Should I be 'casting' those building blocks as custom widgets? My guess is that Qt has a concept for that which I can't find because I don't know what it's called.

Thanks for your help!

You would create custom classes based on QWidget or some other simple widget class (QFrame for instance). It's pretty standard practice, no need for another concept.
