python-3.x - 在 Tkinter 中使用 anchor

Question

我正在尝试对自动点唱机进行编程，但是我处于早期阶段，并且在使用 anchor 时遇到了问题.

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()

我的问题是因为当我把相册放在左边时我的空间用完了我想开始把它们放在中间所以我用了anchor = 'n'但是它把它们都移到了底部。

请有人能帮我找到一种方法，从顶部中间开始堆叠我的专辑。

我正在使用python 3。

对于您想做的事情，grid几何似乎是一个更好的主意，您可以明确编码项目的位置，而不是让 pack几何隐含地确定它将去哪里。
另一个改进是拥有 Frame你把每张专辑放在哪里Button .
我已经编辑了你的一段代码:

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()

这是你想要的吗？
