python-3.x - 我想将来自多个文本框的值加起来并插入到最终的文本框中
问题描述
我的文件包含 106 个框架、62 个文本框和 183 个单选按钮，它们会将值插入关联的文本框中。每个文本框都与 3 个单选按钮相关联。每个文本框都将从选定的单选按钮中获取值。
我的目标是将 textbox1 到 textbox61 中的所有值加起来，然后将该值插入到 textbox62 中。
我从我的原始文件中附加了 4 帧及其单选按钮和文本框。Deff 7 打印框架或生成名称错误 textbox2 未定义
我知道这远远超出了我的水平，如果我看到一段代码，我可以进入项目的最后阶段。我的下一步将是根据 textbox62 中的值打开一个框架 提前致谢。

解决方案
分组Radiobuttons需要链接到同一个IntVar。它可能更容易使用Labels而不是Texts. 下面是通用 2 组应用程序的代码。它用于DoubleVars维护标签文本并允许对 Var 字段进行简单的求和。
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
group1 = tk.IntVar()
group2 = tk.IntVar()
v0 = tk.DoubleVar( value = 0.0 )
v1 = tk.DoubleVar( value = 0.0 )
v_tot = tk.DoubleVar()
def do_sum():
v_tot.set( v0.get() + v1.get() )
def do_group1():
ix = group1.get()
v0.set( { 1: 2.82, 2: 5.66, 3: 8.49 }[ix] )
do_sum()
def do_group2():
ix = group2.get()
v1.set( { 1: 8.83, 2: 17.66, 3: 26.49 }[ix] )
do_sum()
spacer = { 'padx': 3, 'pady': 3 }
# Group 1
r = 0
ttk.Label( root, text = 'Group 1 : ').grid( row = r, column = 0, **spacer )
ttk.Label( root, text = "", textvariable = v0 ).grid( row = r, column = 1 )
ttk.Radiobutton( root, text = 'Button 1', variable = group1, value = 1,
command = do_group1 ).grid( row = r, column = 2, **spacer )
ttk.Radiobutton( root, text = 'Button 2', variable = group1, value = 2,
command = do_group1 ).grid( row = r, column = 3, **spacer )
ttk.Radiobutton( root, text = 'Button 3', variable = group1, value = 3,
command = do_group1 ).grid( row = r, column = 4, **spacer )
# Group 2
r = 1
ttk.Label( root, text = 'Group 2 : ').grid( row = r, column = 0)
ttk.Label( root, text = "", textvariable = v1 ).grid( row = r, column = 1 )
ttk.Radiobutton( root, text = 'Button 1', variable = group2, value = 1,
command = do_group2 ).grid( row = r, column = 2, **spacer )
ttk.Radiobutton( root, text = 'Button 2', variable = group2, value = 2,
command = do_group2 ).grid( row = r, column = 3, **spacer )
ttk.Radiobutton( root, text = 'Button 3', variable = group2, value = 3,
command = do_group2 ).grid( row = r, column = 4, **spacer )
# Total
r = 3
ttk.Label( root, text = 'Total : ').grid( row = r, column = 0)
ttk.Label( root, text = "", textvariable = v_tot ).grid( row = r, column = 1 )
root.mainloop()
根据您在下面的评论， 我尝试对问题中的代码进行最小更改，并在 frame3 中显示总和。这回答了你的问题了吗？
onclick7可以由每个人执行onclickX以保持运行总计，并且根本不需要总计按钮。
应该可以减少onclickX使用 s 中返回的值的数量IntVar。这将使以后的维护更容易。
