QTabWidget refuses to automatically resize

I am trying to have the following layout in qtcreator:

QWidget
  QSplitter
    QStackedWidget
      ...
    QStackedWidget
      QWidget (page)
        QTabWidget

Each control with is sizePolicyassigned a value Expanding. Despite this, neither the tab widget, nor anything else that I started on the page widgets, is not authorized.

I'm new to Qt, so forgive me if this is an obvious solution. Thank.

You need the following hierarchical note QLayout):

QWidget
  QSplitter
    QStackedWidget
      ...
    QStackedWidget
      QWidget (page)
        QLayout
          QTabWidget

So, the code looks something like this:

QLayout* MyLayout = new QVBoxLayout (MyPageWidget) ;
MyLayout -> setSpacing (0) ;
MyLayout -> setContentsMargins (0, 0, 0, 0) ;
MyLayout -> addWidget (MyTabWidget) ;
