Question

我正在尝试在我正在编写的wxpython应用程序中为我的一个页面添加一个Gauge。

我的标准python代码读取zip文件的文件夹并写入CSV。

我有两个问题，如何使我的量程范围与找到的文件数相匹配，其次如何将量表的值设置为处理的文件数。

我的整个代码都在下面。

所以我在第3页设置了一个标尺，当convertFiles正在运行时，我希望guage更新为计数值。

我已经尝试了很多教程并获得了大量的

未定义对象进度

我非常感谢任何帮助

如果你想要计算目录中找到的文件，我喜欢使用Python的glob模块。它会返回一个结果列表，您可以抓住它的长度。如果你想要一个zip文件中的文件数量，我想你可以使用Python的zipfile模块通过namelist（）方法将它拉出来。

现在已经不在了，您可以使用文件列表的长度创建wx.Gauge小部件作为Gauge的“range”参数。然后在convertFiles（）方法的末尾，您只需调用gauge的SetValue（）方法。 wxPython演示有一个例子。
