我在 wxpython 中创建了一个带有菜单栏的框架，并将主尺寸调整器设置为框架本身的子级，但在调整框架大小后，框架的面板保持固定大小。当移除菜单栏并将主尺寸调整器设置为面板本身时，调整大小可以完美地工作，但是将菜单添加到框架中，将主尺寸调整器设置为面板不起作用。

tl;dr - 此代码的面板大小保持固定。如何使其可调整大小？

import wx

class Mainframe(wx.Frame):
def __init__(self,parent,title):
    wx.Frame.__init__(self,parent,title=title,size=(650,450))
    self.Main_Panel = wx.Panel(self,id=wx.ID_ANY)

    self.Menu_SaveAs_File = Filemenu.Append(wx.ID_SAVEAS,"Save as","Normal saving will be incorporated later")
    Filemenu.AppendSeparator()
    self.Menu_About_Dialog = Filemenu.Append(wx.ID_ABOUT,"About","Information about the program and changelog")
    self.Debug_State_Switch = Debugmenu.Append(wx.ID_ANY,"Debug on","Turn on debug mode",wx.ITEM_CHECK)

    Menubar.Append(Filemenu,"File")
    Menubar.Append(Debugmenu,"Debug")

    Left_Static_text.SetLabel("Exploitable text")

    Left_Text_Control = wx.TextCtrl(self.Main_Panel,wx.ID_ANY,value="Exploitable")

    Buttons = []

    # self.Main_Panel.SetSizer(Whole_Sizer) <- THIS WORKS WITHOUT A MENU
    self.SetSizer(Whole_Sizer)

app = wx.App(False)
frame = Mainframe(None,"Menu UI")
frame.Show(True)
app.MainLoop()

原来这只是一个小故障。在WindowsWhole_Sizer中归因于Main_Panel时，所有的小部件都位于左上角。一旦我开始通过拖动整个窗口的角来弄乱窗口大小，整个事情就自行解决了。现在我只觉得愚蠢。
