我正在创建一个 Tabpanel1，Tabpanel2，它将成为 Notebook 的一部分。在该 TabPanel1 中，还有 3 个面板。panel1a，panel1b，panel1c

panel1a 的父 id 参数应该是什么。它应该是 TabPanel1 吗？

代码.py

import random
import wx

class TabPanel1(wx.Panel):
    #----------------------------------------------------------------------
    def __init__(self, parent):
        """"""
        wx.Panel.__init__(self, parent=parent)

        colors = ["red", "blue", "gray", "yellow", "green"]
        self.SetBackgroundColour(random.choice(colors))

    panel1 = wx.Panel(self,size=(400,100))
    panel1.SetBackgroundColour('brown')

    panel1gs = wx.GridSizer(2,2,1,2)

    panel1gs.AddMany( [ (wx.StaticText(panel1,label='FirstLabel'),0,wx.EXPAND),
            (wx.StaticText(panel1,label='SecondLabel'),0,wx.EXPAND),
            (wx.StaticText(panel1,label='ThirdLabel'),0,wx.EXPAND),
            (wx.StaticText(panel1,label='FourthLabel'),0,wx.EXPAND)
            ] )



    panel1.SetSizer(panel1gs)

    panel2 = wx.Panel(self,size=(400,100))
    panel2.SetBackgroundColour('#4f5042')

    panel3 = wx.Panel(self,size=(400,100))
    panel3.SetBackgroundColour('#4f5042')

        btn = wx.Button(self, label="Press Me")

    sizer.Add(panel2, 0, wx.ALL, 5)
    sizer.Add(panel3, 0, wx.ALL, 5)

简单地说，parent对象的 是它将出现在里面的对象。此外，当父级被销毁时，子级将被销毁，在隐藏时隐藏，等等。

因此，如果panel1a、panel1b和panel1c都出现在 内部 panel1，那么panel1对于父母来说是最好的选择，因为它最接近那些孩子。panel1，反过来，在里面TabPanel1，所以它的父母是TabPanel1。理解？

TabPanel1.__init__()顺便说一句，您的方法中似乎存在一些缩进错误。希望这只是剪切和粘贴到 SO 中的错误。
