嵌套面板的 Wxpython 大小及其在调整整个应用程序大小时的行为

Question

我的问题是关于 "panelThree" 在代码中的行为。我给它上色，这表明我的面板中的 space 非常小。我真的不知道我在哪里犯了错误。关于 panelThree 行为的第二件事是，当您最大化整个应用程序并返回到默认大小时，它会变得很奇怪，可能是因为它没有背景，但它与以前的连接。

代码如下：

import wx
import wx.aui
import wx.grid as gridlib

我认为你的问题是你没有在里面放任何东西。
尝试将 class MenuPanel 更改为：

class MenuPanel(wx.Panel):
    """"""

    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)

        notebook = wx.Notebook(self)
        page = wx.SplitterWindow(notebook)
        text_ctrl = wx.TextCtrl(notebook, style=wx.TE_MULTILINE)
        text_ctrl.SetValue("A whole bunch of text\nand then some more\nand finally some more")
        menuSplitter = wx.SplitterWindow(page)

        Color = ColorPanel(page)
        Color.SetBackgroundColour((193,255,193))

        notebook.AddPage(text_ctrl, "Colors Menu")
        #notebook.AddPage(page, "Colors Menu2")
        #notebook.AddPage(page, "Colors Menu2")
        #notebook.AddPage(page, "Colors Menu2")
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(notebook, 1, wx.EXPAND)
        self.SetSizer(sizer)

这加入了text_ctrl里面有一些数据，看看区别！
如果您打算使用 AuiNoteBook，您可能应该阅读或重新阅读这篇文章 http://www.wiki.wxpython.org/AuiNotebook%20%28AGW%29
虽然 wx.Aui 将自己标记为前沿，但可能存在问题，因为它不会像更普通的标准版本那样经过广泛测试，在这种情况下 wx.NoteBook.
