range-loop

Finds places where you're using C++11 range-loops with non-const Qt containers (potential detach).

Fix it by marking the container const, or, since Qt 5.7, use qAsConst():

Example

for (auto i : qAsConst(list)) { ... }

Also warns if you're passing structs with non-trivial copy-ctor or non-trivial dtor by value, use const-ref so that the copy-ctor and dtor don't get called.

Fixits

This check supports adding missing & or const-& with:
