在wxPython中，如何访问wxPython类中静态文本（或任何）控件的值

如何从PanelOne类中的tmpPath获取值？我读过很多东西，但不明白这一点

我如何才能使上述代码工作，请向我解释为什么

        xfile=PanelOne.tmplPath.GetValue()

您的“tmplPath”对象是wxStaticText。 您已使用“SetLabel”更改它显示的文本，因此要获取此文本，必须使用“GetLabel”：

谢谢你。但是，在第“xfile=PanelOne.tmplPath.GetLabel（）”行中，我收到以下消息“AttributeError:type对象'PanelOne'没有属性'tmplPath'。我不明白如何从Panel2引用PanelOne.tmplPath。我做错了什么。
