Python XRC Buttons not clickab

Question

我正在开发一个python应用程序，遇到了一个问题。我的目标是有一个包含许多控件的主框架和一个面板，它将从运行时指定的xrc文件加载。基本上，当用户单击一个按钮时，我希望从一个xrc文件填充一个面板，xrc文件是根据单击哪个按钮来选择的。在

我正在用XRCed定义UI，下面是我目前所拥有的。这似乎将子面板控件加载到框架中，但它们不可单击，而且它们也不会像我希望的那样出现在DynamicPanel中。你的帮助将不胜感激。在

我修改了我的主代码，现在控件出现在它们在框架中的位置，但是按钮仍然无法单击。谁能告诉我为什么吗？在

Python代码：

import wx.xrc as xrc

        self.Bind(wx.EVT_BUTTON, self.OnButton_1, self.button1)
        self.Bind(wx.EVT_BUTTON, self.OnButton_2, self.button2)
        self.Bind(wx.EVT_BUTTON, self.OnButton_Clear, self.Button_Clear)
