如果您只想显示数据（即不需要GUI），则可能需要看一下SDL：直接从像素数据创建表面，然后将其显示在屏幕上很简单。
受Artelius的回答启发，我还破解了一个示例程序：
#include <SDL/SDL.h>#include <assert.h>#include <stdint.h>#include <stdlib.h>#define WIDTH 256#define HEIGHT 256static _Bool init_app(const char * name, SDL_Surface * icon, uint32_t flags){ atexit(SDL_Quit); if(SDL_Init(flags) < 0) return 0; SDL_WM_SetCaption(name, name); SDL_WM_SetIcon(icon, NULL); return 1;}static uint8_t * init_data(uint8_t * data){ for(size_t i = WIDTH * HEIGHT * 3; i--; ) data[i] = (i % 3 == 0) ? (i / 3) % WIDTH : (i % 3 == 1) ? (i / 3) / WIDTH : 0; return data;}static _Bool process(uint8_t * data){ for(SDL_Event event; SDL_PollEvent(&event);) if(event.type == SDL_QUIT) return 0; for(size_t i = 0; i < WIDTH * HEIGHT * 3; i += 1 + rand() % 3) data[i] -= rand() % 8; return 1;}static void render(SDL_Surface * sf){ SDL_Surface * screen = SDL_GetVideoSurface(); if(SDL_BlitSurface(sf, NULL, screen, NULL) == 0) SDL_UpdateRect(screen, 0, 0, 0, 0);}static int filter(const SDL_Event * event){ return event->type == SDL_QUIT; }#define mask32(BYTE) (*(uint32_t *)(uint8_t [4]){ [BYTE] = 0xff })int main(int argc, char * argv[]){ (void)argc, (void)argv; static uint8_t buffer[WIDTH * HEIGHT * 3]; _Bool ok = init_app("SDL example", NULL, SDL_INIT_VIDEO) && SDL_SetVideoMode(WIDTH, HEIGHT, 24, SDL_HWSURFACE); assert(ok); SDL_Surface * data_sf = SDL_CreateRGBSurfaceFrom( init_data(buffer), WIDTH, HEIGHT, 24, WIDTH * 3, mask32(0), mask32(1), mask32(2), 0); SDL_SetEventFilter(filter); for(; process(buffer); SDL_Delay(10)) render(data_sf); return 0;}
