How can I get the date out of QFileInfo?

[d_stranz]

Second I changed the declaration for sizeItem to:
QTableWidgetItem *sizeItem = new QTableWidgetItem(tr("").arg(fdate.toString()));

And didn't I tell you in reply to your last post (in the "General Discussion" section) how to properly format a QString().arg() expression?

We aren't going to write your code for you, and you have to read and understand the answers so you can write it yourself.
