填写时 Tkinter 检查按钮干扰

Question

我正在制作一个 g.u.i。与 tkinter。我目前正在尝试制作几个带有几个复选按钮的标签框。问题是一个检查按钮在一个窗口中被交叉，而另一个窗口中的另一个也被交叉。

我一直在寻找类似的问题，但没有找到。作为一个初学者，我真的不明白问题出在哪里。

import tkinter as tk
from tkinter import ttk
from tkinter import messagebox
from scipy.stats import linregress
import pandas as pd

window= tk.Tk()
#creating the  2 labelframes
models = tk.LabelFrame(window, text="Models", padx=10, pady=10)
models.grid(padx=10, pady=10, sticky='W')
param = tk.LabelFrame(window, text="params", padx=10, pady=10)
param.grid(column=0, row=10, sticky='W', padx= 10)
# adding checkbuttons to the first labelframe
lin_cb = tk.Checkbutton(models, text="linear regression")
lin_cb.grid(column=0, row=2, sticky='W')
nlin_cb = tk.Checkbutton(models, text="non-linear regression")
nlin_cb.grid(column=0, row=5, sticky='W')
#labels for second labelframe
tk.Label(param, text="substate").grid(row=1, sticky='W')
tk.Label(param, text="velocity").grid(row=2, sticky='W')
tk.Label(param, text="if inhibited").grid(row=3, sticky='W')
tk.Label(param, text="inibitor").grid(row=4, sticky='W')
#checkbutton
su_M=tk.Checkbutton(param, text='M')
su_M.grid(column=1, row=1, sticky='W')
su_mM=tk.Checkbutton(param, text='mM')
su_mM.grid(column=2, row=1, sticky='W')

window.mainloop()

在继续程序从交叉的复选按钮中提取信息之前，我必须了解如何解决这个问题。谢谢大家。我希望我给了你所有必要的信息。我尽量把代码总结一下。

要使用Checkbutton，您需要创建 tkinter 变量并将它们与每个 Checkbutton 关联。

import tkinter as tk

window= tk.Tk()
models = tk.LabelFrame(window, text="Models", padx=10, pady=10)
models.grid(padx=10, pady=10, sticky='W')
param = tk.LabelFrame(window, text="params", padx=10, pady=10)
param.grid(column=0, row=10, sticky='W', padx= 10)

all_vars = [tk.IntVar() for _ in range(4)] #create 4 IntVars in one go
for i in all_vars : #set all vars to 0
    i.set(0)

lin_cb = tk.Checkbutton(models, text="linear regression",variable=all_vars[0])  #set variable for each checkbutton
lin_cb.grid(column=0, row=2, sticky='W')
nlin_cb = tk.Checkbutton(models, text="non-linear regression",variable=all_vars[1])
nlin_cb.grid(column=0, row=5, sticky='W')

tk.Label(param, text="substate").grid(row=1, sticky='W')
tk.Label(param, text="velocity").grid(row=2, sticky='W')
tk.Label(param, text="if inhibited").grid(row=3, sticky='W')
tk.Label(param, text="inibitor").grid(row=4, sticky='W')

su_M=tk.Checkbutton(param, text='M',variable=all_vars[2])
su_M.grid(column=1, row=1, sticky='W')
su_mM=tk.Checkbutton(param, text='mM',variable=all_vars[3])
su_mM.grid(column=2, row=1, sticky='W')

window.mainloop()
