Should I use Qt containers or the std ones?
If you come from plain vanilla C++, you only know the C++ Standard
Library with its containers like std::vector. If you know how to use
them, you can accomplish your tasks pretty fast. But if you’re coming
from another language, the naming might be a bit odd. The Qt containers
offer both, C++ style and Java style naming of methods. So coming from
another language the Qt one’s might be easier to use.
