        在QFIleDialog.getOpenFileName()函数中 
        第一个参数self：用于指定父组件 
        第二个参数‘open file’：是QFileDialog对话框的标题 
        第三个参数‘C:\’默认打开的目录，‘.’代表程序运行的目录，‘/’代表当前盘下的根目录(window.linux系统),需要注意的是不同路径的显示方式，比如window平台下的C盘“C:\”等 
        第四个参数是对话框中文件扩展名过滤器（fliter）,比如使用’Image files (.jpg .gif .png .jpeg)’表示只能显示扩展名为.jpg,.gif等文件
