デフォルト値でラジオボタンの 2D グリッドを作成しようとしています。グリッドは最大 256 行ですが、常に 3 列です。私は多くのことを調査し、多くのオプションを試しましたが、これが今のところ最良のコードです。明らかに、私は Python と Tkinter を初めて使用するので、私のジレンマ (およびコード作成) を解決するための追加の提案は大歓迎です。また、ラジオ ボタンの各行を読み返して、どのラジオ ボタンがチェックされたかを判断する必要があることにも注意してください。

import Tkinter as tk
from Tkinter import *

class GUI(Frame):
    def __init__(self, parent):
        Frame.__init__(self, parent)
        self.parent = parent
        self.pack()
        self.initUI()

    def initUI(self):
        # the 5Hz radio button should be selected as default
        self.freqs=['1Hz','5Hz','10Hz']
        self.numFreqs = len(self.freqs)
        #val and var are set up to try to establish the defaults
        #every 3 vals = 1 var therfore the middle val should = var
        # val 0,1,2 = var 1 , val 3,4,5 = var 4 , val 6,7,8 = var 7
        # this should allow the 5hx radiobuttonto be default selected
        self.val = [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14]
        self.var=[1,4,7,10,13]
        self.var[0] = IntVar()
        self.var[1] = IntVar()
        self.var[2] = IntVar()

        self.rButtons1 = []
        self.rButtons2 = []
        self.rButtons3 = []

        self.textLbls = ['Choice 1', 'Choice 2', 'Choice 3','Choice 4','Choice 5']

        #build enough values for 256 rows of 3 radiobuttons
        #For var = [1,4,7,10...  val = [0,1,2,  3,4,5,  6,7,8... so vars match vals on the 5hz radiobutton
        #Can't do this since it creates the'many already selected bug'

        for i in range(len(self.textLbls)):
            temp = self.val[(self.numFreqs*i)+1]
            temp1 = self.var[i]
            self.cButtons.append(Checkbutton(self, text=self.textLbls[i], onvalue=1, offvalue=0))

            Label(self, text='         Frequency:').grid(row=i, column=6)
            #variable connects group of radios for slection/clear of group
            #if value = variable this is default
            self.rButtons1.append(Radiobutton(self,  text=self.freqs[0], variable=self.var[i], value=self.val[(self.numFreqs*i)+0]))

            self.rButtons3.append(Radiobutton(self,  text=self.freqs[2], variable=self.var[i], value=self.val[(self.numFreqs*i)+2]))

このコードでどのような問題を解決する必要があるかは完全にはわかりませんが、もう少し機能的になるようにいくつかの簡単な変更を加えました。

import tkinter as tk
from tkinter import *

class GUI(Frame):
    def __init__(self, parent):
        Frame.__init__(self, parent)
        self.parent = parent
        self.pack()
        self.initUI()

    def initUI(self):
        # the 5Hz radio button should be selected as default
        self.freqs=['1Hz','5Hz','10Hz']
        self.numFreqs = len(self.freqs)
        #val and var are set up to try to establish the defaults
        #every 3 vals = 1 var therfore the middle val should = var
        # val 0,1,2 = var 1 , val 3,4,5 = var 4 , val 6,7,8 = var 7
        # this should allow the 5hz radiobutton to be default selected
        self.val = [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14]
        #You only really need to hold on to a reference to the IntVars, not the
        # entire widgets.  Declaring each "var" individually is also unneccesary
        self.checkButtonVars = []
        self.radioButtonsVars = []

        self.textLbls = ['Choice 1', 'Choice 2', 'Choice 3','Choice 4','Choice 5']
        #(your comment block)

        valueIter = iter(self.val)  #This will let us read the values 3 by 3
        for i,lbl in enumerate(self.textLbls):      #enumerate is a nice way to avoid range(len(x))
            tempVals = [next(valueIter) for x in range(3)]  #get the next 3 values
            #make a variable for the new CheckBox (and append it to our list)
            self.checkButtonVars.append(IntVar(value=0))
            #make a variable for the new RadioButton group (and append it to our list)
            self.radioButtonsVars.append(IntVar(value=tempVals[1]))

            #Make the checkboxes, radiobuttons and label for the line.
            Checkbutton(self, text=lbl, variable=self.checkButtonVars[i]).grid(row=i, column=2, sticky = W)
            Label(self, text='         Frequency:').grid(row=i, column=6)
            Radiobutton(self,  text=self.freqs[0], variable=self.radioButtonsVars[i], value=tempVals[0]).grid(row=i, column=7, padx=5)
            Radiobutton(self,  text=self.freqs[1], variable=self.radioButtonsVars[i], value=tempVals[1]).grid(row=i, column=8, padx=5)
            Radiobutton(self,  text=self.freqs[2], variable=self.radioButtonsVars[i], value=tempVals[2]).grid(row=i, column=9, padx=5)

        #I added a button to retrieve the values, this is just as a demo.
        self.printButton = Button(self,text='Return values',command=self.printVals)
        self.printButton.grid(row=i+1,column=8)


    def getRadioVals(self,*args):
        #returns the values in the radio buttons as a list
        return [x.get() for x in self.radioButtonsVars]

    def getCheckVals(self,*args):
        #returns the values in the checkboxes as a list
        return [x.get() for x in self.checkButtonVars]

    def printVals(self,*args):
        print('Radio Buttons: %s' %(self.getRadioVals()))
        print('Check Buttons: %s' %(self.getCheckVals()))


def main():
    root = Tk()
    app = GUI(root)
    root.mainloop()

if __name__ == '__main__':
    main()

抱えている特定の問題をより詳しく説明できれば、それらの問題に対処できる可能性があります。

また、注意として、256 個のラジオボタンを垂直に表示しようとすると、問題が発生する可能性があります。私の知る限り、標準の tkinter でスクロール フレームを作成する方法はないため、ウィンドウは画面よりもはるかに高くなります。
