dangling unicode string?

[Guest]

Hi, I'm trying to display a unicode string on a QMessageBox from the QTableWidget horizontalHeaderItem,
using the code below:
@ wchar_t c[300];
QString s;
s = qtw->horizontalHeaderItem(0)->text();
s.toWCharArray(c);
QMessageBox::information(0,0,QString::fromWCharArray(c));
@
the horizontalHeaderItem's text is correctly drawn, however I get on the MessageBox a dangling unicode string containing the horizontalHeaderItem's text plus other dangling characters that are not part from the horizontalHeaderItem's text.
so what's wrong here? and how to solve that problem? thanks.

I can't see anything wrong with that code excerpt.

However, it could be simplified to:
@QString s = qtw->horizontalHeaderItem(0)->text();

//pointer remains valid, until ``s´´ is modified/deleted!
const wchar_t c = (const wchar_t) s.utf16();

QMessageBox::information(0,0,QString::fromUtf16((const ushort*)c));@
