Connecting to QML Signals. All QML signals are automatically available to C++, and can be connected to using QObject::connect() like any ordinary Qt C++ signal. In return, any C++ signal can be received by a QML object using signal handlers. Here is a QML component with a signal named qmlSignal that is QML Signal and Handler Event System | Qt 4.8 Because QML uses Qt, a signal defined in C++ also works as a QML signal. The signal may be emitted in QML code or called as a method. In addition, the QML runtime automatically creates signal handlers for the C++ signals. For more signal control, the connect() method and the Connections element may connect a C++ signal to another signal or method.
