QString strOut;
QTextStream streamOut(&strOut);
//打印多种进制数字
streamOut<<800;
```
实例二:
赋值给变量
```
QString strIn = QObject::tr("800 abcd 123.789999");
QTextStream streamIn(&strIn);
int numDec = 0;
QString strSub;
double dblReal = 0.0;
//输入到变量里
streamIn>>numDec>>strSub>>dblReal;
```
实例三:
读取文件
```
QFile file("D:\\code\\hello_qt\\http\\mainwindow.cpp");
file.open(QIODevice::ReadOnly);
QTextStream stream(&file);
while (!stream.atEnd()) {
qDebug()<>nCode;
if( 9 == nCode )
{
tsOut<< a.tr("程序结束。")<
';
