wxpython：如何用在其他位置創建的網格填充“筆記本”選項卡？

Question

現在，我有一個用wxpython構建的GUI，它可以成功地從.csv中提取數據，填充wx網格對象，然后將其顯示在新框架中。 我還成功地打開了主窗口，以筆記本樣式顯示一些信息。 我的目標是做到這一點，以便在我運行程序時，一個主頁選項卡包含與之前創建的窗口相同的填充網格。 讓我感到困擾的問題是，網格的創建和網格填充（兩件分開的事情）是在不同（但已導入）本地文件中的不同類中完成的。 此外，下面的代碼在我的程序上下文中提供了AttributeError：'TabPanel'對象沒有屬性'con'，這很有意義，但是我沒有

這是不可能的嗎？或者我有什么想念的（甚至我還很清楚嗎？）？ 以下是我想可能是相關代碼的內容。 （為方便起見，類和構造函數行的間距不正確。）非常感謝！

制表/筆記本電腦：

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")

您不能在兩個不同的父對象中顯示完全相同的窗口小部件。 相反，創建獨立框架時需要創建empGrid實例，而創建筆記本時則需要創建其他實例。

實例化empGrid時，會將筆記本面板/頁面作為父面板傳遞給它。 創建框架時，您將框架（或其面板）作為父級傳遞。
