A helper function, qOverload, was added to mitigate this (in 5.7): http://doc-snapshots.qt.io/qt5-5.7/qtglobal.html#qOverload Anyway, you can make it decent enough if you organize a bit with an intermediate typedef: using valueChangedSignal = void(QSpinBox::*)(int); auto valueChangedPointer = static_cast<valueChangedSignal>(&QSpinBox::valueChanged); connect(ui->cacheSize, valueChangedPointer, this, &SyncWidget::changeCacheLimits); connect(ui->cacheAge, valueChangedPointer, this, &SyncWidget::changeCacheLimits); If you really really need the overloads, and you use them in connections a lot, maybe you could even provide the typedef (and the pointer, if you don't think it's too much) in your own classes. -- Alex (a.k.a. suy) | GPG ID 0x0B8B0BC2 http://barnacity.net/ | http://disperso.net _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
