请问:如何从一个文本File构造一个QTextStream? [复制链接]

我用函数:QTextStream::QTextStream ( FILE * fileHandle, QIODevice::OpenMode openMode = QIODevice::ReadWrite )

具体如下：
QFile file;
file.open(QIODevice::ReadOnly);
stream(file);

结果报错：error C2064: term does not evaluate to a function taking 1 arguments

QFile file("file.txt");
file.open(QIODevice::Text |QIODevice::ReadOnly);
QTextStream in(&file);
QString strWord;
in >> strWord;
