QSharedPointer - does it work well when constructed independently?

[Septi]

Suppose there is one object in my program, and several shared pointers for it. Will they count references to the object, if they are not created with assigning value to one another, but by constructing each independently from simple pointer.

Like, this:

MyObject *object = new MyObject;
QSharedPointer <MyObject> a, b, c, d;
a = QSharedPointer (object);
b = QSharedPointer (object);
c = QSharedPointer (object);
d = QSharedPointer (object);

MyObject *object = new MyObject;
QSharedPointer <MyObject> a, b, c, d;
a = QSharedPointer (object);
b = QSharedPointer (object);
c = QSharedPointer (object);
d = QSharedPointer (object);

To copy to clipboard, switch view to plain text mode 

instead of this:

MyObject *object = new MyObject;
QSharedPointer <MyObject> a, b, c, d;
a = QSharedPointer (object);
b = a;
c = b;
d = c;

MyObject *object = new MyObject;
QSharedPointer <MyObject> a, b, c, d;
a = QSharedPointer (object);
b = a;
c = b;
d = c;

To copy to clipboard, switch view to plain text mode

The first example won't work since the shared pointers have no knowledge of each other and object will get deleted four times over.

Uh-oh, now I have to redesign my code a little. I thought they were counting references in some sort of static structure ((

Well, spud, thanks for clarifying it.
