Qt使用Windows Api模拟键盘事件，附Qt::key转windows键值

VOID WINAPI keybd_event(
_In_ BYTE      bVk,
_In_ BYTE      bScan,
_In_ DWORD     dwFlags,
_In_ ULONG_PTR dwExtraInfo
);

keybd_event(key, 0x45, KEYEVENTF_EXTENDEDKEY, 0);//按键按下
keybd_event(key, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);//按键松开

int translateKeyCode(int key)
