[Qt-qml] Connecting to a property's C++ signals in QML

[ext-salonen.olli at nokia.com]

Hi,

Is there a way to connect to the signals of a QObject in QML if it has been set as a context property? I would like to do the following:

MyObject.h
----------------
Class MyObject {
  Q_OBJECT
signal:
  void connectMe();
};

main.cpp
----------------
...
QDeclarativeView view;
QDeclarativeContext* context = view.rootContext;
context->setContextProperty("myObject", new MyObject);

main.qml
-----------------
myObject.onConnectMe(): log.debug("triggered")

Is there a legal way to do that last line in QML?

If I just map the C++ object to QML through qmlRegisterType<MyObject>() and then write the QML as follows:

MyObject {
  onConnectMe: log.debug("triggered")
}

then I cannot control the construction of the object. It cannot even be constructed if the object has a mandatory constructor parameter.

Thanks in advance,
Olli
