    该代码需在创建QApplication实例之前
    解决在ubuntu系统下出现的报错：具体如下：
    [xcb] Unknown request in queue while appending request [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb]
    Aborting, sorry about that.
    python: ../../src/xcb_io.c:151:
    append_pending_request: Assertion `!xcb_xlib_unknown_req_pending'
    failed
