wxpython：如何将其他地方创建的网格填充到Notebook标签中？

Question

现在我有一个用wxpython做的图形界面，它可以成功地从一个.csv文件中提取数据，填充到一个wx网格对象里，然后在一个新窗口中显示出来。我还成功地让我的主窗口以笔记本的形式显示一些信息。我的目标是让我的程序运行时，主页面的一个标签里包含和我之前制作的窗口一样的填充网格。现在让我困惑的问题是，网格的创建和填充（这两件事是分开的）是在不同的类中完成的，而且这些类是在一个不同的（但已导入的）本地文件里。此外，我在程序中运行的下面这段代码出现了AttributeError: 'TabPanel'对象没有属性'con'，这让我觉得有道理，但我不太明白。

这是不是不可能，还是我漏掉了什么（我说得清楚吗）？下面是我猜测相关的代码。（为了方便，这里类和构造函数的缩进不太正确。）非常感谢！

标签/笔记本：

class TabPanel(wx.Panel):    
    def __init__(self, parent):
        wx.Panel.__init__(self, parent=parent, id=wx.ID_ANY)

        self.sizer = wx.BoxSizer(wx.VERTICAL)
        txtOne = wx.Panel(Employee.EmployeeViewAllFrame(self).show())

        self.sizer.Add(txtOne, 0, wx.ALL , 50)

        self.SetSizer(self.sizer)


class NotebookDemo(wx.Notebook):
    def __init__(self, parent):
        wx.Notebook.__init__(self, parent, id=wx.ID_ANY, style=
                         wx.BK_DEFAULT
                         #wx.BK_TOP 
                         #wx.BK_BOTTOM
                         #wx.BK_LEFT
                         #wx.BK_RIGHT
                         )

        # Create the first tab and add it to the notebook
        tabOne = TabPanel(self)
        tabOne.SetBackgroundColour("BLUE")
        self.AddPage(tabOne, "Main")

        # Create and add the second tab
        tabTwo = TabPanel(self)
        self.AddPage(tabTwo, "Employees")

        # Create and add the third tab
        self.AddPage(TabPanel(self), "Tasks")

网格/窗口：
