qdebugstream-usage.cpp

QT4的utils库源码包.解压后运行./configure配置,然后make.使用时在.pro文件中加入两行:LIBS+=-L$$(CPPLIBS)-lutils及INCLUDEPATH+=$$(C

/* Example of how to create streams cout and error, but at the same time
   to redirect the std::cout and std:cerr both to the same stream as
   qDebug.
*/

#include <qdebugstream.h>
{
    // create your application
    QApplication app(argc, argv);
    // these redirect both cout/cerr
    QDebugStream qdsout(std::cout);
    QDebugStream qdserr(std::cerr);
    // now start using cout and cerr normally
    std::cerr << "Oops"; // this goes to your debugger output
