Many C++ classes in Qt utilize a data sharing mechanism to maximize resource usage and minimize copying of data. ... A reference count. The data. When a shared object is created, it sets the reference count to 1. The reference count is incremented whenever a new object references the shared data, and decremented when the object dereferences the shared data. ... These classes have a detach() function that can be called if you want your object to get a private copy of the shared data. ...
