我有一些麻烦，让一切正确地使用Tkinter和Python网格排列。我想把菜单栏放在最上面，然后是两个列表框（两边各一个），在窗口中间有几个按钮。

目前，两个列表框都显示在窗口的右下角，按钮位于左上角，与菜单按钮重叠。

考虑到列表框的大小，如何处理其网格布局。它们可以占用多个网格单元吗？例如，如果我在（行=1，列=1）中放置一个列表框，在（行=1，列=2）中放置另一个列表框，Tkinter会自动加宽单元格，使其成为列表框的宽度，还是只与列表框重叠？

def __init__(self,root):
    self.frame = Frame(root, width=500)
    self.frame.pack()
    self.BuildMainWindow(self.frame)
    self.ListboxSet = 0 
    self.frame.grid()
    return

#displays the menu bar and options
def BuildMainWindow(self, frame):
    menubar = Frame(frame,relief=RAISED,borderwidth=1)
    menubar.pack()

    mb_file = Menubutton(menubar,text='file')
    mb_file.menu = Menu(mb_file)
    mb_file.menu.add_command(label='open', command = self.openfile)
    mb_file.grid(row = 1, column = 1)

    mb_edit = Menubutton(menubar,text='edit')
    mb_edit.menu = Menu(mb_edit)
    mb_edit.grid(row=1, column = 3)

    mb_file['menu'] = mb_file.menu
    mb_edit['menu'] = mb_edit.menu

#upon selecting a directory from the menu and listboxes/buttons are created
def BuildListbox(self, directory):
    self.listbox1 = Tkinter.Listbox()
    self.listbox2 = Tkinter.Listbox()
    self.listbox1.grid(row=2, column=1)
    self.listbox2.grid(row=2 ,column=10)
    self.listbox2.bind('<<ListboxSelect>>', lambda e:SortActions.GetWindowIndex(self,e))
    self.listbox2.bind('<B1-Motion>', lambda e:SortActions.MoveWindowItem(self,e))

    i = 0
    for filename in sorted(os.listdir(directory)):
        self.listbox1.insert(i, filename)
        i = i + 1

    self.bAddToListTwo = Button(self.frame, text = "->", command = lambda:SortActions.AddToListTwo(self,self.listbox1.curselection()))
    self.bAddToListTwo.grid(row=5, column = 5)
    self.bAddAll = Button(self.frame, text = "Add All To Playlist", command = lambda:SortActions.AddAllFiles(self))
    self.bAddAll.grid(row=6, column = 5)
    self.bRemoveFromListTwo = Button(self.frame, text = "Remove From Playlist", command = lambda:SortActions.RemoveFromListTwo(self,self.listbox2.curselection()))
    self.bRemoveFromListTwo.grid(row=7, column = 5)
    self.bSavePlaylist = Button(self.frame, text = "Save Playlist", command = lambda:SortActions.SaveList(self))
    self.bSavePlaylist.grid(row=8, column = 5)

更新-我让它工作了。正如我所怀疑的，我在初始化过程中有一些奇怪的帧配置。
