I'm trying to use a multidimensional array:
QList<QList<QVariant> > info;
//Append QList<QVariant> works...
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?
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).
Thank you Krysztorf Kawa!
