Thanks guys for your answers. I found what I was seeking. And what about parentheses and QMetaMethod that I wanted to concretize what I mean under new syntax of connection.
As new connect method is: QMetaObject::Connection QObject::connect(const QObject * sender, const QMetaMethod & signal, const QObject * receiver, const QMetaMethod & method, Qt::ConnectionType type = Qt::AutoConnection) so I have written in parantheses: (using QMetaMethod).

If I ignore the parentheses above, the answer is yes. If I include the parentheses, I have to ask: what does QMetaMethod have to do with the new connection syntax? I'm not sure you understand what you're asking. > For example, QComboBox::currentIndexChanged... There are two signals with > int and QString... > > Or for such connection user *must* use old syntax? You need to cast the pointer-to-member-function to the type that you want. You do that via static_cast or by assigning it to a PMF variable. void (QComboBox:: *signal)(int) = &QComboBox::currentIndexChanged; connect(comboBox, signal, this, &MyClass::doSomething); -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
