QSet Move Insertion of Explicitly Shared Objects (C++11 & QSharedData Paradigm)

[wysota]

The issue I am having is that when one of these objects is inserted into QSet, QSet duplicates the object when adding it to the set using the object's copy constructor instead of the move constructor.

That's the correct behaviour, if you ask me...

I want the object's data to be "moved into" the set... not copied in. I have tried using QSet<Object>.insert( std::move( object ) ), but no matter what I do the copy constructor is called instead of the move constructor.

How are you creating "object"?

Besides, if you have explicitly shared data, I don't see any serious benefits of "moving" the data. With explicit sharing you are only copying a pointer and bumping up the reference counter (1 or 2 machine instructions).
