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? — MrFox, Jan 31 '13 at 20:59

can you try doing setWidgetResizable(true) for your QScrollArea

ScrollArea->setWidgetResizable(true);

A couple of suggestions:

Ensure that the size policy of the scroll area itself is Expanding.
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).
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. — andre, Feb 13 '13 at 14:20
