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.
