Qt Creator/Designer problems with Tab Widget

[JonB]

Using Qt Creator/Designer (4.8.1, Linux). Trying to put a Tab Widget (QTabWidget) on the layout and having problems accessing the individual tabs (QWidgets).

The designer creates hierarchy:

tabWidget (QTabWidget)
    tab (QWidget)
    tab_2 (QWidget)

I need each tab to be a QScrollArea, which can then have the tab QWidgets as the widget to scroll.

I have spent way too long trying to make the end application work right where we retain the existing hierarchy and start adding the QScrollAreas as a child widget (via a layout) of the existing tab QWidget ones. (Things go wrong with scrolling. I spent a day trying to get it right, I can't carry on like this.).

Now, I searched and all the examples of using QTabWidget (not designed from Qt Creator, but that's what there is) for scrolling say the hierarchy only should be:

tabWidget (QTabWidget)
    scroll (QScrollArea)
        tab (QWidget)
    scroll_2 (QScrollArea)
        tab_2 (QWidget)

So they make the QTabWidget child be QScrollArea, not plain QWidgets. I have tried this by "hacking" the final code and that works great for the scrolling, so that's what I'd like to do.

But how to achieve it from Designer? I need the Morph into... context menu item for each QWidget tab. But when I select the tab (click on label), the context menu only gives me Page 1 of 2 > Delete or Promote to.... No Morph on the tabs, only for the whole tab widget. I cannot make the tabs be selected in the Object inspector by clicking in the main area. I can click on them in Object inspector, but that context menu does not offer Morph. ?

If you really want to object to my desire for QTabWidget > QScrollArea > QWidget instead of QTabWidget > QWidget > QLayout > QScrollArea > QWidget please say so, but as I said I tried that and for whatever reason did not get the scrolling behaviour right.
