Python XRC按钮不可点击

Question

我正在开发一个python应用程序，并遇到了障碍。我的目标是拥有一个包含大量控件的主框架，以及一个将从运行时指定的xrc文件加载的面板。基本上，当用户单击按钮时，我希望从xrc文件中填充一个面板，根据单击的按钮选择xrc文件。

我用XRCed定义了UI，这是我到目前为止所拥有的。这似乎将子面板控件加载到框架中，但它们不可单击，并且它们不会像我希望的那样出现在DynamicPanel中。非常感谢您的帮助。

修改

我修改了我的主代码，现在控件出现在框架中的位置，但按钮仍然无法点击。谁能告诉我为什么？

Python代码：

import wx
import wx.xrc as xrc


from UNTITLED_xrc import xrcFRAME1

class XrcFrameSubClass(xrcFRAME1):
    """"""
    #----------------------------------------------------------------------
    def __init__(self):
        xrcFRAME1.__init__(self, parent = None)

        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)

        self.Show()


    def OnButton_Clear(self, event):
        self.ClearSubPanel()

    def ClearSubPanel(self):

            self.SubPanel.Destroy()
            self.Fit()
            self.Layout()
        except:
            pass
