    I fail to get QScrollArea dimensions, I tried geometry(), width(), height() and others but I always get understimated dimensions of the real borders.
    Ho can I do?

      you mean like
      QScrollArea f;
      f.viewport()->contentsRect();
      ?

        I have this code:

        • centralWidgetContainer = new QScrollArea(this);
          CentralWidget* centralWidget = new CentralWidget(centralWidgetContainer);
          centralWidgetContainer->setWidget(centralWidget);
          centralWidgetContainer->setMinimumHeight(this->height() - centralWidgetContainerSizeGap);
          centralWidgetContainer->setMidLineWidth(this->width());

        When I try (from inside CentralWidget, that extends QFrame) something like:

        • QRect rect = ((QScrollArea*)this->parent())->viewport()->contentsRect();

        I got a rect with very understimate height and width values (respect this->height() and this->width() of the code above).

          well I think QMainwindow centralwidget have a default layout so
          maybe its the one altering the rect.

          Do you try to reserve some space or what is the purpose?
