Re: Access a QVariant (of a custom class) in QML



I was getting the impression this was a C++ issue and not a C++/QML mixing issue.


In general you want to set all your pointers to NULL in the constructor as a matter of course, because you should be deleting them in the destructor and that could potentially get called before the secondary objects have all be constructed/initialized.  Good to learn the hard way though.

Re: Access a QVariant (of a custom class) in QML

just to report that back, as we now discussed two pages in a resolved thread:
declaring the signal objects as QObject* is still neccessary for QML to access them, so the solution of this thread by Kyle is valid.
The other issues (discussed after the solution) all derived from passing invalid (not initialized) pointers to QML.
