QList inside a QList

[gsmiko]

Hi jano_alex_es!

It is possible, the only problem is that QList::at returns a const reference to the item, use the [] operator instead. Of course, a new list should be added to my_list first.

QList<QList<QPointF> > my_list;
QList<QPointF> my_subList;
QPointF my_point(0, 10);
my_list.append(my_subList);
my_list[0].append(my_point);

QList<QList<QPointF> > my_list;
QList<QPointF> my_subList;
QPointF my_point(0, 10);
my_list.append(my_subList);
my_list[0].append(my_point);

To copy to clipboard, switch view to plain text mode 

It's not the best example, because my_point could be added to my_subList, and then my_subList to my_list.
