在Tkinter中使用Anchor

Question

我正在尝试编写一个自动点唱机，但是我还处于早期阶段，在使用anchor时遇到了一个问题。

这是我的代码；

from tkinter import *
from tkinter import messagebox as box



def main_menu():
    window = Tk()
    window.title('Juke Box')
    window.geometry('800x480')
    window.configure(background = 'black')

    label = Label(window, text = 'Juke-Box', fg = 'light green', bg = 'black', font = (None, 30), height = 2)
    label.pack(side = TOP)

    Jam = Button(window, text = 'The Jam', width = 25, height = 2)
    Jam.pack(pady = 10, padx = 25, anchor = 'w')

    Roses = Button(window, text = 'The Stone Roses', width = 25, height = 2)
    Roses.pack(pady = 10, padx = 25, anchor = 'w')

    Smiths = Button(window, text = 'The Smiths', width = 25, height = 2)
    Smiths.pack(pady = 10, padx = 25, anchor = 'w')

    Wedding = Button(window, text = 'The Wedding Pressent', width = 25, height = 2)
    Wedding.pack(pady = 10, padx = 25, anchor = 'w')

    Blondie = Button(window, text = 'Blondie', width = 25, height = 2)
    Blondie.pack(pady = 10, padx = 25, anchor = 'w')

    Clash = Button(window, text = 'Clash', width = 25, height = 2)
    Clash.pack(pady = 10, padx = 25, anchor = 'w')

    Madness = Button(window, text = 'Madness', width = 25, height = 2)
    Madness.pack(pady = 10, padx = 25, anchor = 'n')

    Pistols = Button(window, text = 'The Sex Pistols', width = 25, height = 2)
    Pistols.pack(pady = 10, padx = 25, anchor = 'n')

    window.mainloop()



main_menu()

我的问题是，当我在左边堆叠相册时，我已经用完了空间，我想开始往下堆叠它们，所以我使用了anchor = 'n'，但是它把它们都移到了底部。

请谁能帮我找到一种方法，从顶部开始堆叠我的相册中间。

我使用的是python 3。

对于你想要做的事情，grid几何结构似乎是一个更好的主意，你可以显式地编码项目的位置，而不是让pack几何图形隐式地决定它将去哪里。另一个改进是在您放置每个专辑Button的地方有一个Frame。我已经编辑了你的代码：

from tkinter import *
from tkinter import messagebox as box

def main_menu():
    window = Tk()
    window.title('Juke Box')
    window.geometry('800x480')
    window.configure(background = 'black')

    label = Label(window, text = 'Juke-Box', fg = 'light green',
                  bg = 'black', font = (None, 30), height = 2)
    label.pack(side = TOP)

    gridFrame = Frame(window, bg='black') # New frame to store buttons

    # Grid uses sticky instead of anchor, but in this scenario it is not really necessary
    # I have left it in case you need it for some other reason

    Jam = Button(gridFrame, text = 'The Jam', width = 25, height = 2)
    Jam.grid(row=0, column=0, pady = 10, padx = 25, sticky=W) 
    Roses = Button(gridFrame, text = 'The Stone Roses', width = 25, height = 2)
    Roses.grid(row=1, column=0, pady = 10, padx = 25, sticky=W)

    Smiths = Button(gridFrame, text = 'The Smiths', width = 25, height = 2)
    Smiths.grid(row=2, column=0, pady = 10, padx = 25, sticky =W)

    Wedding = Button(gridFrame, text = 'The Wedding Pressent', width = 25, height = 2)
    Wedding.grid(row=3, column=0, pady = 10, padx = 25, sticky =W)

    Blondie = Button(gridFrame, text = 'Blondie', width = 25, height = 2)
    Blondie.grid(row=4, column=0, pady = 10, padx = 25, sticky =W)

    Clash = Button(gridFrame, text = 'Clash', width = 25, height = 2)
    Clash.grid(row=5, column=0, pady = 10, padx = 25, sticky =W)

    Madness = Button(gridFrame, text = 'Madness', width = 25, height = 2)
    Madness.grid(row=0, column=1, pady = 10, padx = 25, sticky =N)

    Pistols = Button(gridFrame, text = 'The Sex Pistols', width = 25, height = 2)
    Pistols.grid(row=1, column=1, pady = 10, padx = 25, sticky =N)

    gridFrame.pack(side=BOTTOM) 
    # Place it a the bottom or top or wherever you want it to go

    window.mainloop()

main_menu()
