我已经编写了一个 wxPython 应用程序（遵循文档），它几乎可以完成我想要的一切。它有我想要的所有方式的复选框和文本行等。唯一的问题是我把它作为我的应用程序的主要框架。

我真正想要的是把它变成一个小部件，这样我就可以在我的最终应用程序框架中实例化其中的一些。然而，当我试图让我的小部件从 wx.Panel 而不是 wx.Frame 继承，然后将一个小部件实例化到我的 Frame 类中时，它像中子星一样自行塌陷。

请看一下我的两个代码示例，看看你是否知道出了什么问题。

这是我的小部件直接在从 wx.Frame 继承的类中构建的版本：

在此先感谢您的帮助。如果我需要提供任何其他信息，请告诉我。

当您将代码从框架转换为自定义面板时，您忘记删除额外的面板；ISC_status（a wx.Panel）在内部创建了另一个面板，由于缺少额外的尺寸器，布局被忽略（当主框架重新计算布局时，它无法到达内部面板）。

我已经移除了那个内部面板（以及一些使它保持小的功能，抱歉），现在它应该可以按照你想要的方式工作：

        self.tamperCheck = wx.CheckBox(self,-1,'Tamper Tripped')
        #make the MAC hbox section
        self.macHbox = wx.BoxSizer(wx.HORIZONTAL)
        self.macLabel = wx.StaticText(self,-1,'MAC ADDR: ')
