QTabBar & QTabWidget

In a complicated scenario when you have several Q classes like view ,scene ,widgets...and in a scene you have to show a widget and a tab....whats the right way to do that....any adivce is welcomed...and also QTab widget shud be used in this scenario or QTab bar is better...

Sorry I think I didn't undestand you so well, but I think you can use QMdiArea that allow you to use differents widgets in it.

Take a look at QtDemo -> Main Windows -> MDI.
