QList inside a QList

[jano_alex_es]

Hi,

I have a QList integrated with other QList<QPointF>, but it's impossible to add elements to the second QList.

For instance, the next code does not compile (2 overloads have no legal conversion for "this" pointer), but it should...

//Please note the blank space between the two ">"
QList<QList<QPointF> > my_list;
QPointF my_point(0, 10);
my_list.at(0).append(my_point);

//Please note the blank space between the two ">"
QList<QList<QPointF> > my_list;
QPointF my_point(0, 10);
my_list.at(0).append(my_point);

To copy to clipboard, switch view to plain text mode 

then... how can I add elements to a lists of lists in qt? is it possible?
