Alex, vous avez raison. I'm an idiot. I had commented out the setSpacing()
calls, and forgotten about it. The code now looks like:

ParagraphRow::ParagraphRow(Row row,
                           QWidget* parent)
{
    QHBoxLayout* para_row_layout = new QHBoxLayout;
    para_row_layout->setSpacing(0);
    para_row_layout->setContentsMargins(0,0,0,0);
...
}

ParagraphList::ParagraphList(const QList<ParagraphRow *>& para_rows,
                             QWidget* parent)
                : QWidget(parent)
{
    QVBoxLayout* para_list_layout = new QVBoxLayout;
    para_list_layout->setSpacing(0);
    para_list_layout->setContentsMargins(0,0,0,0);
...
}

which gives the following result:

Thanks for the help, everyone.

I love Qt's layout system. It gives me hours of fun, everytime I try to use
it.
