how to get current path in qt

method 1:

cout << QDir::currentPath().toUtf8().constData(); //home/tjiang/Workspace/TestQT/build-TestCGAL-Desktop_Qt_5_3_0_GCC_64bit-Debug

method 2:

define a macro in pro file

message($${PWD}) #/home/tjiang/Workspace/TestQT/TestCGAL#message($(PWD)) #/home/tjiangDEFINES += CGAL_EIGEN3_ENABLEDDEFINES += PROJECT_PATH=\\\"$${PWD}\\\"

then use this macro to define a variable in cpp file

    QString projectPath(PROJECT_PATH);    cout << projectPath.toUtf8().constData();
