QScrollArea ->setWidget(this) doesn't produce a ScrollArea. Why?

[wysota]

Change the "widgetResizable" property of the scroll area to true. Also bear in mind your construction is very weird (or at least unusual). You allow test2 to be created with a parent and then you place it inside some other widget (the scroll area) that reparents the widget to itself. Furthermore there is no reference to the window (scroll area) outside the test2 object which leads to a certain memory leak.

Diph already pointed out the source of error: I forgot that I don't get the QScrollArea fro free when I have it inside a Widget, I need to add the QScrollArea and not the Widget to the layout.

I have Destructors which delete every object created including the scroll area from the test2 destructor equivalent in my non-test code. Or is there something else about memory leaks I should be aware of?

So when exactly do you delete the scroll area object? Actually I see the question is meaningless as you didn't want the scroll area to be a top level widget, despite what your code says...

[planetLars]

I delete the scrollbar when the class2-equivalent gets destroyed. And class2 gets deleted when the main application gets destroyed. I wanted my class2-equivalent be a self contained widget which (I can place anywhere and which) brings its own scroll area without the user having to fuss with scrollbars.

Don't you think it should inherit QScrollArea or QAbstractScrollArea then?

This was a question. I ponder it further. Thanks. Good Night.
