Example #1

File: main.go Project: BurntSushi/go-wayland-simple-shm

func main() {
	disp := newDisplay()
	win := newWindow(disp, 250, 250)

	redraw(unsafe.Pointer(win), nil, 0)

	C.wl_display_iterate(disp.display, C.uint32_t(disp.mask))

	time.Sleep(5 * time.Second)
}

Example #2

	disp := &display{}
	disp.display = C.wl_display_connect(nil)
	fmt.Printf("Type of wl_display value: %T\n", disp.display)

	if disp.display == nil {
		panic("Could not connect to Wayland.")
	}

	C._wl_display_add_global_listener(disp.display, unsafe.Pointer(disp))
	C.wl_display_iterate(disp.display, C.WL_DISPLAY_READABLE)
	C.wl_display_roundtrip(disp.display)
