Scrollable background with resizable Qt widgets on it

I would like to create a Qt window that

  1. can be scrolled/panned by dragging its background (scrollbars should not be shown)
  2. contains multiple sub-widgets at defined locations (which scroll with the background)
  3. the sub-widgets can be resized by pulling their border

What I managed so far is to create a QGraphicsView with setDragMode(QGraphicsView::ScrollHandDrag) http://doc.qt.io/qt-5/qgraphicsview.html#dragMode-prop. I then placed the sub-widgets on a QGraphicsScene, however, this didn't allow the sub-widgets to be resized by pulling their border. I also tried to inherit my custom sub-widget class from QDialog, which allows setSizeGripEnabled(true). However, this doesn't resize their content, and QDialog is probably not meant to be part of a QGraphicsView.

Any suggestions? It would also be ok if the sub-widgets behave like sub-windows that can also be dragged at their title bar, as long as they cannot be closed and they move when the background is dragged.

You can look aside QMdiArea class (Qt documentation: QMdiArea). By problem description it is what you need. Of course, you can use Graphics View Framework, but, i think, it will be more difficult. If you choose such approach, very useful will be class QGraphicsWidget (Qt documentation: QGraphicsWidget).
