How to Handle Window Close Events in SDL

How can I make my SDL window respond to close events, such as clicking the close button?

To make your SDL window respond to close events, you need to modify your event handling loop to detect when the SDL_QUIT event is triggered, which occurs when the window's close button is clicked. Here's how you can incorporate this into your code:

#include <SDL.h>
#include "Window.h"

int main(int argc, char** argv) {
  Window GameWindow;
  SDL_Event event;
  bool running = true;

  while (running) {
    while (SDL_PollEvent(&event)) {
      if (event.type == SDL_QUIT) {
        running = false; 
      }
    }
    GameWindow.Update();
  }

  SDL_Quit();
  return 0;
}

This modification introduces a boolean flag running that controls the main loop. The loop continues as long as running is true, but sets running to false when an SDL_QUIT event is detected, effectively closing the window.
