<![CDATA[Problem with new connect syntax]]>Hello,

Here is the new syntax :

@ QObject::connect(m_actionAbout, &QAction::triggered,
qApp, &QApplication::aboutQt);@

But dsnt work :/

@FenPrincipale.cpp:69: erreur : C2664: 'QMetaObject::Connection QObject::connect(const QObject *,const char *,const QObject *,const char ,Qt::ConnectionType)' : cannot convert parameter 2 from 'void (__thiscall QAction:: )(bool)' to 'const char *'
There is no context in which this conversion is possible@

Can you help ? thanks

So things like sender() or connectNotify() won't work. (And even a disconnect?)

<code>QObject::connect(m_actionAbout, &QAction::triggered, { qApp->aboutQt(); });</code>
