C++ und SDL Grafikfenster 5

Das fünfte SDL Grafikfenster erzeugt einen roten Hintergrund…

Quellcode für C++ und das SDL Grafikfenster 5:

#include <SDL2/SDL.h>
#include <iostream>

int main(int argc, char* argv[]) {
    // Initialize SDL
    if (SDL_Init(SDL_INIT_VIDEO) != 0) {
        std::cout << "Error initializing SDL: " << SDL_GetError() << std::endl;
        return 1; // Exit with error code
    }

    // Create a window
    SDL_Window* window = SDL_CreateWindow("Fensterprogramm 5", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 800, 600, SDL_WINDOW_SHOWN);
    if (!window) {
        std::cout << "Error creating window: " << SDL_GetError() << std::endl;
        return 1; // Exit with error code
    }

    // Create a renderer for the window
    SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);
    if (!renderer) {
        std::cout << "Error creating renderer: " << SDL_GetError() << std::endl;
        return 1; // Exit with error code
    }

    bool quit = false;

    while (!quit) {
        // Handle events (e.g., closing the window)
        SDL_Event event;
        while (SDL_PollEvent(&event)) {
            if (event.type == SDL_QUIT) {
                quit = true;
            }
        }

        // Clear the renderer
        SDL_SetRenderDrawColor(renderer, 255, 0, 0, 255);
        SDL_RenderClear(renderer);

        // Draw something on top of the blue background

        // Update the window and renderer
        SDL_RenderPresent(renderer);
    }

    // Clean up resources when done
    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
