Question

我正在编写一个程序来保持14-1台球（池）比赛的得分。由于我需要多个窗口，所以我使用了tkinter帧。 2页的框架可以解决困难。我的问题是输入数据。每个玩家姓名中输入的第一个项目。两个文本框都出现在屏幕上，并且可以输入数据。如果我在输入后尝试显示数据，我什么也得不到。我已经做了好几天了。而且我确定有人可以看一下，然后说嘿嘿笨拙的头，你确实这样做了。适当的一些帮助。

import tkinter as tk
from tkinter import *


TITLE_FONT = ("Helvetica", 18, "bold")
TITLE_FONT_LINE2 = ("Helvetica", 14, "bold")

    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)

        # the container is where we'll stack a bunch of frames
        # on top of each other, then the one we want visible
        # will be raised above the others

        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand=True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}
        for F in (StartPage, PageOne, PageTwo):

            self.frames[page_name] = frame

            # put all of the pages in the same location;
            # the one on the top of the stacking order
            # will be the one that is visible.

我看不到任何尝试访问文本条目窗口小部件的内容。因此，您的代码完全符合我的期望。

如果您想阅读文本条目小部件的内容，您应该创建一个StringVar来保存内容

self.playerone = StringVar()
self.entry1 = ttk.Entry(parent, textvariable=playerone)

然后可以从playerone变量的内容中读取条目的内容，例如playeronename = self.playerone.get()（当然变量必须使用带有命名空间的完全限定名称）

上的条目小部件有文档

您的代码和帖子太乱了。关于你的问题：我建议你使用GET方法，从每个输入框中使用GET方法获取数据，然后将其归为变量，这是从输入框中获取数据的最简单方法。在像你这样的应用程序中，我在输入框附近创建按钮，在命令属性中我做了类似这样的事情

bttn = Button(self, text='enter', command=self.txt_box.get(0, END))

在tkinter帧中输入数据
