Qt C++项目总结6：读写文本文件

写：

QString strFilePathName = "C:\abc.txt";
QFile data(strFilePathName);
if (data.open(QFile::WriteOnly | QIODevice::Text))//| QIODevice::Truncate
{
    QTextStream out(&data);
    out << "hello" << endl;
    out << "2nd line" << endl;
    out << "3rd line" << endl;
｝

QString strFilePathName = "C:\abc.txt";

QFile data(strFilePathName);

if (data.open(QFile::WriteOnly | QIODevice::Text))//| QIODevice::Truncate

{

QTextStream out(&data);

out << "hello" << endl;

out << "2nd line" << endl;

out << "3rd line" << endl;

｝
