Hello guys, it's my first post here. I started to play with SFML and I have quite strange problem. I want to write letters '1' or '0' in my board. I want it to show immediately after I press 1 or 0 but can't really do it well. Here's my void. It should draw 1 or 0 in a position immediately after I press1 or 0 and it actually does, but after I want to print another number the previous one is getting hidden.
void tablica::rysowanie_cyfr(sf::RenderWindow & window)
{
        int a = 50;
        int b = 50;
        sf::Event event;
        bool wait = true;
                for (int i = 0;  i<4; i++) {
                        for (int j = 0;  j<4; j++) {
                                sf::Text *text = new sf::Text;
                                text = set_properties(window);
                                while (wait) {
                                        while (window.pollEvent(event)) {
                                                if (event.type == sf::Event::KeyReleased) {
                                                        if (event.key.code == sf::Keyboard::Num1) {
                                                                text->setPosition(a, b);
                                                                text->setString("1");
                                                                wait = false;
                                                                window.draw(*text);
                                                       
                                                        }
                                                        else if (event.key.code == sf::Keyboard::Num0)
                                                        {
                                                                text->setPosition(a, b);
                                                                text->setString("0");
                                                                wait = false;
                                                                window.draw(*text);
                                                        }
                                                }
                                        }
                                }
                                delete text;
                                wait = true;
                                a += 100;
                                window.display();
                        }b += 100; a = 50;
        }
}
It is summoned in a main loop like this
if (wait == true) {
                        tabela.rysowanie_cyfr(window);
                }
 
wait is set at false and when i press a button I set wait as true.
Please, help me :(
Also sorry for my english it's not my native language. If you have problems with understanding my problem I can explain it futher.

You're doing setString("0") or setString("1") which will set the string to EXACTLY "0" or "1".
If you want to add numbers afterwards, you need to do text.setString(text.getString() + "whatevertextyouwanthere").

Also, PLEASE do not do

if (booleanVariable == true)

just do

if (booleanVariable)

It's just cleaner.
