Title: Making a sf::RenderWindow
Post by: DylanMorgan on February 16, 2017, 08:28:19 pm

Hey guys, so I have a game class where I have the private variable

sf::RenderWindow window;

I want to set the windows properties in the constructor of game and then so I can use the window throughout the game class. I will use a getWindow function if I do need to use the window elsewhere. However, I do not understand how to create the window outside of me defining it. I don't know if it is a simple mistake or... Any help is appreciated!

I am not sure if I have understood you correctly, but if you want want to (re)create your window, there's sf::Window::create (https://www.sfml-dev.org/documentation/2.4.2/classsf_1_1Window.php#a30e6edf2162f8dbff61023b9de5d961d) method dedicated to exactly this purpose.

You want to create the window in the constructor of the class instead of at the time of declaring the variable?

You can specify the parameters in the construction of it in the constructor's member initializer list:

class Game
{
public:
    Game();
private:
    sf::RenderWindow window;
}

Game::Game()
    : window(sf::VideoMode(800, 600), "Game")
{
}

or, as sjaustirni said, you can later create the window - or recreate an already-created window - by using window's create() method.
Same example as above but this time using the create method:

class Game
{
public:
    Game();
private:
    sf::RenderWindow window;
}

Game::Game()
{
    window.create(sf::VideoMode(800, 600), "Game");
}

Thank you for the replys guys :) I decided to use the window.create() function
