dynamic matrix of QStrings

I think the problem is not QObject (where is it anyway? I don't see any QObjects here), but instead this:

this[r].resize(columns);

this[r].resize(columns);

To copy to clipboard, switch view to plain text mode 

As "this" is a pointer, you're trying to use an index operator on a pointer, which doesn't make any sense. Either use at() or dereference "this" first:

(*this)[r].resize(columns);

(*this)[r].resize(columns);

To copy to clipboard, switch view to plain text mode

Oops... you are right...
Now I see that QVector is not a QObjet...
But I thought (obviously was wrong) that in Qt4 all cllases derived QObject.
Hmm, I better read the docs again...
Sorry about that. (wrong info).

QVector is a template class itself, so it couldn't be a QObject.

Naaa... QObject is quite heavy, so it's better to avoid it if you don't need it. Besides, you could do multiple inheritance then ("Remember, multiple inheritance is a beautiful thing!" )

You are right of course, didn't really think it through...
