connect a signal to lambda function

ODБOï

Hi,
I'm trying to connect a signal to a lambda function like this:

//main.cpp
FileLoader fl;
   QObject::connect(
        fl, &FileLoader::objChanged,
        [=]( const QString &newValue ) { qDebug()<< "lambda called..";}
    );

the signal is defined like this :

void  objChanged(QString)

this is the output :

C:\udp_inspector\main.cpp:25: erreur : no matching function for call to 'QObject::connect(FileLoader&, void (FileLoader::*)(QString), qMain(int, char**)::<lambda(QString)>)'
     QObject::connect(fl,FileLoader::objChanged,[=](QString newObj){qDebug()<<newObj;});
                                                                                      ^

Can someone tell me how to do this please ?

The first argument must be a pointer to QObject.
Change QObject::connect(fl, &FileLoader::objChanged, [=]( const QString &newValue ) { qDebug()<< "lambda called..";}); to QObject::connect(&fl, &FileLoader::objChanged, [=]( const QString &newValue ) { qDebug()<< "lambda called..";});
