Building SDL2 from Source (GCC and Make)

Creating Multiple Windows with SDL2

How can I create multiple windows in an SDL2 application?

SDL2 allows you to create multiple windows within a single application. Here's an example of how to create two windows:

#include <SDL.h>

int main(int argc, char* argv[]) {
  SDL_Init(SDL_INIT_VIDEO);

  SDL_Window* window1{SDL_CreateWindow(
    "Window 1",
    SDL_WINDOWPOS_UNDEFINED,
    SDL_WINDOWPOS_UNDEFINED,
    800, 600, SDL_WINDOW_SHOWN
  )};

  SDL_Window* window2{SDL_CreateWindow(
    "Window 2",
    SDL_WINDOWPOS_UNDEFINED,
    SDL_WINDOWPOS_UNDEFINED,
    400, 300, SDL_WINDOW_SHOWN
  )};

  SDL_Event event;
  bool quit = false;
  while (!quit) {
    while (SDL_PollEvent(&event)) {
      if (event.type == SDL_QUIT) {
        quit = true;
      }
    }
  }

  SDL_DestroyWindow(window1);
  SDL_DestroyWindow(window2);
  SDL_Quit();

  return 0;
}

In this example, we create two windows using SDL_CreateWindow, each with different titles and sizes. The windows are displayed simultaneously, and the event loop handles events for both windows.

Remember to destroy each window using SDL_DestroyWindow before quitting the application.

You can also create and manage windows dynamically during the application's runtime based on your specific requirements.
