sf::Window inheritance [SOLVED]
« on: July 10, 2012, 10:08:15 am »
I've inherited sf::Window in one of my projects, however the compiler gives a bunch of warnings. Also I see sf::NotCopyable class inheritance in the warnings, no virtual destructor. To get to my question, is sf::Window not meant to be inherited?

Because I need a specialized sf::Window.

No, it's just not meant to be copied.

Here is the compiler output mentioned here.

Oh, ok. Nothing's wrong, you should just disable -Weffc++ if you don't want these warnings to show.
