[Qt-interest] Passing QList<QStringList> as arguments

[Malyushytsky, Alex]

As somebody mentioned  place where you put your includes is important.

>> ror: variable ‘QList<QStringList> rows’ has initializer but incomplete type

An error below might be related to usage forward declaration
(for example no includes yet, but compiler already need to know about type to proceed)

The easiest way to check it place all includes in the header file where you declare the function.

Those are my headers:

#include <QtGui>
#include <QList>
#include <QString>
#include <QStringList>

and still got he error.

Sounds like you did not copy over the needed #include's as well. Your
compiler has currently no idea what a QList<QStringList> is supposed to
be. You need to point it to the place where it can find that.
