QSharedDataPointer detach too much ( don't call const )
-
Hello
example
https://pastebin.com/xL9yWhKeI never used QSharedDataPointer in my code but is is heavily used in Qt
My problem is that I found that QSharedDataPointer prefer non const operator for access raw pointer to object instead of const variant.
And at the end non const variant call detach() = cloning object
Look at my example and plz debug if conditionsI use compiler MSVC 2015, 2017
My problem is that for example QTextCursor use this constructions and it heavily call detach. And simple call const variant of method should fix this.
Anybody can explain this behaviour?
