problem - printing in windows and linux

[newplayer]

Why can't I use function print() in linux ? In windows I can and in linux I can't:
my function:

void MyWindow::Print()
{
    QPrintDialog x (&printer,this);
    if (x.exec() == QDialog::Accepted)
    {
        textbox -> print (&printer);
    }
}

void MyWindow::Print()
{
    QPrintDialog x (&printer,this);
    if (x.exec() == QDialog::Accepted)
    {
        textbox -> print (&printer);
    }
}

To copy to clipboard, switch view to plain text mode 

mistake:

error: ‘class QTextEdit’ has no member named ‘print’

error: ‘class QTextEdit’ has no member named ‘print’

To copy to clipboard, switch view to plain text mode

possibly you use too old a Qt version under Linux (esp. a different one)?
This function was added in 4.3.
