QScrollArea widget is not expanding with a Flowlayout

Question

I have a ui with a QScrollArea Widget. The QScrollArea uses a Flowlayout. My problem is when I add widgets to my layout the scroll area begins to scroll and does not expand when it has room to expand. I want the scroll area to expand to its limit before the scroll bar appears first.

How can I get the scroll area to expand before the scroll bar appears?

What does the layout look like for the widget that the QScrollArea is sitting in? Is there a layout? – Aquarelle

@suslik The QScrollArea sits in a QFrame Widget. – Tupper

Answer 1

can you try doing setWidgetResizable(true) for your QScrollArea

ScrollArea->setWidgetResizable(true);

Answer 2

A couple of suggestions:

1. Ensure that the size policy of the scroll area itself is Expanding.

2. Set the "stretch" values of the size policy of the scroll area to a value greater than that of the other widgets in the same layout. Ie:

   QSizePolicy policy = pScrollArea->sizePolicy()
   
   policy.setVerticalStretch(1);
   policy.setHorizontalStretch(1);
   

   This assumes that the siblings of the scroll area (if any) have a stretch value of 0 (the default).

3. Subclass the scroll area and override the sizeHint() method.

Thanks for the suggestions. I've tried 1 and 2 and will work on 3 shortly. – Tupper
