SDL2 DropEvent minimal example

gistfile1.txt

#include <SDL2/SDL.h>

int main() {
    SDL_Init(SDL_INIT_EVERYTHING);
    SDL_Window *window = SDL_CreateWindow("Drag-and-Drop", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 800, 600, SDL_WINDOW_SHOWN);
    int running = 1;

    while (running) {
        SDL_Event event;
        while (SDL_PollEvent(&event)) {
            switch (event.type) {
            case SDL_DROPFILE:
                printf("Dropped file: %s\n", event.drop.file);
                break;
            case SDL_QUIT:
                running = 0;
                break;
            }
        }
    }

    SDL_DestroyWindow(window);
    SDL_Quit();
}

Got this by random, and I would like to note, that you should free event.drop.file (after using it for something, here just printf() it), otherwise you have some memory leak every time you have a file drop event. If I am correct here ... But hmm, I guess this is more like a demonstration where it's not so much an issue :)

fun fact: if said free requirement is correct, the majority of SDL2 applications have in-built memory leaks regarding dropped files
(EDIT: Note: I'm agreeing. The API implies this is most likely the case. It's quite horrifying.)
