Removing the last item in a layout or inserting a widget at the second-to-last spot?

[ChrisW67]

QWidget *newWidget = ...;
 
layout->insertWidget(layout->count() - 1, newWidget);

QWidget *newWidget = ...;

layout->insertWidget(layout->count() - 1, newWidget);

To copy to clipboard, switch view to plain text mode 

seems the obvious approach.

You can probably do away with the spacer item (I assume) altogether using the layout's size constraint.

Hey, thanks alot. I've checked for a layout->count() type function and missed it. I was looking for a size(), I've been working with the C++ standard library too long. =)
I also thought of widget->children().count(), but the parent might have non-layout children, and the layout itself doesn't own the children it has.

If I altered the layout's size constraint, and only have, say, 3 objects in the layout, if those widgets are less than the QScrollArea size (fixed minimum size), the QScrollArea would make the widget hover in the center, instead of at the top... or so I assumed, but another perusal of the documentations says otherwise (QScrollAreas have alignments, which I forgot about, plus it defaults to top-left and not the center).
