It allows objects to communicate with each other without having to have knowledge of either ones internals. By inheriting from `QObject` and defining a few `Q_PROPERTY` macro's, the QT Meta Object Compiler (`moc`) does all the hard work for you. Inside a C++ class this all works handy dandy and is reasonable easy to follow, but when using QML it requires a bit more work. This small example shows you how to bind QML and C++ together using signals and slots, in QT 5.12. Thu, 25 Feb 2021 00:00:00 GMT Thu, 25 Feb 2021 00:00:00 GMT
