Class inheriting sf::RenderWindow properties.

[KasHKoW]

Hi, I'm wondering if making a class sf::RenderWindow properties and adding a few vectors possibly of growing and sometimes depleting memory will be too expensive to actually have act as a sf::RenderWindow?

Could you clarify what you're wanting to do, I'm not quite sure what you mean.

Are you saying you want to inherit from RenderWindow and add a few vector members?

Or a class which has a member Renderwindow which it manages?

Or something else?

I want to make a class derived from sf::RenderWindow. I'm not sure if that's a good idea or if I should just have something that is somewhat an addon but not sf::RenderWindow. This is because I want to add a lot of vectors and I don't know if that will slow down the sf::RenderWindow since it is somewhat the backbone or foundation of the whole program.

You know with drawing functions, opening it, manipulating it... Sending it through functions etc.

Whether it is in a derived class or not, it will still be outside sf::RenderWindow itself, so it's doesn't matter.
You can have a derived class with GB of data, it makes no difference at all for the base class -- it doesn't know about this extra data.
