wxpython/wxwizard仪表问题

Question

我试图在我正在编写的wxpython应用程序的一个页面中添加一个量规。在

我的标准python代码读取一个包含zip文件的文件夹并将其写入CSV。在

我有两个问题，如何使我的量表的范围与找到的文件数相匹配；第二，如何将量表的值设置为已处理的文件数。在

我的全部代码如下。在

所以我在我的第三页上设置了一个量规，当convertFiles正在运行时，我想让量规更新到计数值。在

我试了很多教程，得到了很多

未定义对象进度

我真的很感谢你的帮助

谢谢

如果您想要一个目录中找到的文件的计数，我喜欢使用Python的glob模块。它返回一个结果列表，您只需获取一个长度。如果您想知道zip文件中的文件数，我想可以使用Python的zipfile模块通过namelist（）方法将其拉出。在

现在，您可以创建wx.量规小部件，文件列表的长度作为仪表的“范围”参数。然后在convertFiles（）方法的末尾，只需调用gauge的SetValue（）方法。wxPython演示有一个例子。在
