I'm trying to write my first script in python & tkinter.

I blocked and I'm lost when I need to get in variable the name of each checkboxes selected when I click on the button Validate.

Checkboxes are dynamic from text files. Sample file:

item1

item2

...

item100

A screen of the GUI:

Here's my code:

(In # code is what I tried without success.)

from tkinter import *

from tkinter.ttk import Frame, Label, Entry

import glob



class Example(Frame):



    def __init__(self):

        super().__init__()



        self.initUI()



    def initUI(self):



        self.master.title("My Menu")



        menubar = Menu(self.master)

        self.master.config(menu=menubar)



        fileMenu = Menu(menubar)



        submenu = Menu(fileMenu)

        submenu.add_command(label="lst1", command=self.onDisplay)

        submenu.add_command(label="lst2")

        submenu.add_command(label="lst3")

        fileMenu.add_cascade(label='Listing', menu=submenu, underline=0)



        fileMenu.add_separator()



        fileMenu.add_command(label="Exit", underline=0, command=self.onExit)

        menubar.add_cascade(label="File", underline=0, menu=fileMenu)



    ## Here the function which display checkboxes

    def onDisplay(self):

        self.pack(fill=BOTH, expand=True)

        frame1 = Frame(self)

        frame1.pack(fill=BOTH)

        lbl1 = Label(frame1, text="Choice", width=6)

        path = '/root/liste/*.txt'

        files=glob.glob(path)

        count = 0

        #var = dict()

        for file in files:

            with open(file, 'r') as lst_file:

                for item in lst_file:

                    #var[item]=IntVar()

                    #cb = Checkbutton(frame1, text=item.rstrip(), variable=var[item], command=self.cb)

                    ##Here all checkboxes generated dynamically

                    cb = Checkbutton(frame1, text=item.rstrip())

                    cb.grid(row=count//10, column=count%10)

                    #cb.pack()

                    count += 1

        #btn1 = Button(self, text='Validate', font=("Arial", 12), command=self.cb)

        btn1 = Button(self, text='Validate', font=("Arial", 12))

        btn1.pack(side=RIGHT, padx=5)



    def cb(self):

        print("variable is", self.var.get())



    def onExit(self):



        self.quit()



def main():



    root = Tk()

    root.geometry("800x550+300+300")

    app = Example()

    root.mainloop()





if __name__ == '__main__':

    main()

I can't figure out everything your code is trying to do with respect to handling multiple files, but the following shows a cleaned-up and functioning version of it showing a way to keep track which Checkbuttons have been selected by the user.

Most of the important changes were to the onDisplay() method—although I also changed the name of the def cb(self): method you had to def validate(self): to match the Button name (because I found calling it cb confusing since that's also the name of a local variable in onDisplay()).

from tkinter import *

from tkinter.ttk import Frame, Label, Entry

import glob



class Example(Frame):



    def __init__(self):

        super().__init__()

        self.initUI()



    def initUI(self):



        self.master.title("My Menu")



        menubar = Menu(self.master)

        self.master.config(menu=menubar)



        fileMenu = Menu(menubar)



        submenu = Menu(fileMenu)

        submenu.add_command(label="lst1", command=self.onDisplay)

        submenu.add_command(label="lst2")

        submenu.add_command(label="lst3")

        fileMenu.add_cascade(label='Listing', menu=submenu, underline=0)



        fileMenu.add_separator()



        fileMenu.add_command(label="Exit", underline=0, command=self.onExit)

        menubar.add_cascade(label="File", underline=0, menu=fileMenu)



    ## Here is the function which displays checkboxes

    def onDisplay(self):

        self.pack(fill=BOTH, expand=True)

        frame1 = Frame(self)

        frame1.pack(fill=BOTH)

        lbl1 = Label(frame1, text="Choice", width=6)

#        path = '/root/liste/*.txt'

        path = './root_liste1.txt'  # changed for my testing.

        files=glob.glob(path)



        self.var = dict()

        count = 0

        for file in files:

            with open(file, 'r') as lst_file:

                for item in lst_file:

                    item = item.rstrip()

                    status = BooleanVar()

                    self.var[item] = status

                    cb = Checkbutton(frame1, text=item, variable=status)

                    cb.grid(row=count//10, column=count%10)

                    count += 1



        btn1 = Button(self, text='Validate', font=("Arial", 12),

                      command=self.validate)

        btn1.pack(side=RIGHT, padx=5)



    def validate(self):  # btn1 callback

        print('checked items:')

        for item, status in self.var.items():

            if status.get():  # Checked?

                print('  ', item)



    def onExit(self):

        self.quit()

    root = Tk()

    root.geometry("800x550+300+300")
