I'm implementing mobile viewer for our Geographic Information System (GIM gim.tahal-gal.com/gim2xu/). Some things I thought to move to C++ level, but I met the fact that I can't use in C++ code objects created in QML. Why? Why natural interoperability of QT QML is broken in QT SDK?
I spend few days to understand the problem when I found this this thing in SDK release note:
"Interoperability between identical object instances from both the C++ and QML APIs is not supported. For example, passing a Point geometry object from QML to C++ and performing geometry operations on that Point in C++ is not supported."
Why I can't cast QML Layer to C++ Layer? It is the same objects!!!!
Is this commercial or technical issue?
