Add QMetaMethod::fromSignal() function
Given a member function that's a signal, returns the corresponding QMetaMethod. Inspired by the implementation of the template-based QObject::connect(). The primary use case for this function is to have an effective and exact (not subject to shadowing) way of checking whether a known signal was connected to in reimplementations of QObject::connectNotify(QMetaMethod), avoiding string comparisons. Example: void MyObject::connectNotify(const QMetaMethod &signal) { if (signal == QMetaMethod::fromSignal(&MyObject::mySignal)) { // Someone connected to mySignal ... } } Change-Id: I5e4de434275fe543c004d569dcaa9ceda3442f03 Reviewed-by: Olivier Goffart <> Reviewed-by: Bradley T.
