logger.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

#include <QDebug>
#include <QString>
#include <QDateTime>

#include "logger.h"
#include <QDebug>


QMap<QString, Logger*> Logger::sm_LogMap;


void Logger::myDebugHandler( QtMsgType type, const char *msg ) {
    Q_UNUSED(type);
    Logger* l = getLogger("debug");
    l->data(msg);
}

void Logger::info(QString str) {
    emit data(str);

    if ((str.length()>0) && (objectName() == "debug")) {
		qDebug() << "\nINFO: " <<  QDateTime::currentDateTime().toString() 
             << endl << str;
    }
}

    if (!sm_LogMap.contains(logname)) {
        Logger* log = new Logger(logname);

        }
    }
    return sm_LogMap[logname];
