golang调用sdl2,键盘和鼠标事件

    win10 x64下测试成功，其他操作系统下不保证成功。

    采用的是syscall方式，不是cgo方式。

    见地址

    代码用golang编写。代码如下：

    1. package main
    3. import (
    4.     "fmt"
    5.     "github.com/moonfdd/sdl2-go/sdl"
    6.     "github.com/moonfdd/sdl2-go/sdlcommon"
    7. )
    9. func main() {
    10.     sdlcommon.SetSDL2Path("SDL2.dll")
    11.     sdl.SDL_Init(sdl.SDL_INIT_VIDEO)
    12.     window := sdl.SDL_CreateWindow("微信公众号：福大大架构师每日一题", sdl.SDL_WINDOWPOS_UNDEFINED, sdl.SDL_WINDOWPOS_UNDEFINED, 640, 480, sdl.SDL_WINDOW_OPENGL|sdl.SDL_WINDOW_RESIZABLE)
    13.     if window == nil {
    14.         fmt.Printf("Can't create window, err:%s", sdl.SDL_GetError())
    15.         return
    16.     }
    17.     renderer := window.SDL_CreateRenderer(-1, 0)
    18.     if renderer == nil {
    19.         return
    20.     }
    21.     renderer.SDL_SetRenderDrawColor(255, 0, 0, 255)
    22.     renderer.SDL_RenderClear()
    23.     renderer.SDL_RenderPresent()
    24.     var event sdl.SDL_Event
    25.     for {
    26.         event.SDL_WaitEvent()
    27.         if event.Type == sdl.SDL_KEYDOWN {
    28.             fmt.Println("键盘按下事件", event.ToSDL_KeyboardEvent().Keysym.Sym)
    29.         } else if event.Type == sdl.SDL_MOUSEBUTTONDOWN {
    30.             fmt.Println("鼠标按下事件")
    31.         } else if event.Type == sdl.SDL_QUIT {
    32.             fmt.Println("退出事件")
    33.             break
    34.         }
    35.     }
    36.     if renderer != nil {
    37.         renderer.SDL_DestroyRenderer()
    38.     }
    40.     window.SDL_DestroyWindow()
    41.     sdl.SDL_Quit()
    42. }

    执行结果如下：
