[SOLVED]Multidimensional array

[ranger0]

Hi guys,

I'm trying to use a multidimensional array:

@
QList<QList<QVariant> > info;
//Append QList<QVariant> works...
info.at(0).append(query->value(0));
@

When I try do append same data at info (line 3) I have the error: "error: passing 'const QList<QVariant>' as 'this' argument of 'void QList<T>::append(const T&) [with T = QVariant]' discards qualifiers"

Does anyone has a clue of how to fix this?

Thanks.

Seems like the method from which do execute the code (line 3) is inside a "const" method.

Methods with "const" keyword can read member variables (such as info), but not modify them!

at() returns const reference. Use operator [] instead to modify the list element (the append() modifies it).

It works!

Thank you Krysztorf Kawa!
