Find Checkbutton State

[PEGylated_User]

I am creating a form to have a user input information for making labels. One of the issues I am running into is that I cant figure out how to call for the check button state after the finished button is clicked.

from tkinter import *
from tkinter import ttk


class Stability_Label_Creator():
    def __init__(self, master):
        
        self.notebook = ttk.Notebook(master)
        self.notebook.pack()

        # Add tabs to main window
        self.formulations = ttk.Frame(self.notebook)
        self.stabilityschedule = ttk.Frame(self.notebook)
        self.notebook.add(self.formulations, text = 'Formulations')
        self.notebook.add(self.stabilityschedule, text = 'Stability Schedule')
        
        ttk.Label(self.formulations, text = 'Formulation Name').grid(row = 0, column = 3)
        ttk.Label(self.formulations, text = 'Formulation Lot Number').grid(row = 0, column = 4)
        for x in range(1, 26):
            RowLabel = 'RowLabel' + str(x)
            RowLabel = ttk.Label(self.formulations, text = x)
            RowLabel.grid(row = x, column = 1)

            FormulationVar = 'FormulationVar' + str(x)
            FormulationVar = BooleanVar()
            Formulation = 'Formulation' + str(x)
            Formulation = ttk.Checkbutton(self.formulations, text = '', variable = FormulationVar, onvalue = True, offvalue = False)
            Formulation.grid(row = x, column = 2)
            FormulationVar.set(False)

            FormulationName = 'FormulationName' + str(x)
            FormulationName = ttk.Entry(self.formulations, width = 30)
            FormulationName.grid(row = x, column = 3)  

            FormulationLot = 'FormulationLot' + str(x)
            FormulationLot = ttk.Entry(self.formulations, width = 30)
            FormulationLot.grid(row = x, column = 4)

        self.NextButton = ttk.Button(self.formulations, text = 'Next', command = self.Next)
        self.NextButton.grid(row = 26, column = 4)

        ttk.Label(self.stabilityschedule, text = 'Time Point').grid(row = 0, column = 2)
        ttk.Label(self.stabilityschedule, text = 'Storage Conditions').grid(row = 0, column = 3, columnspan = 7)
        ttk.Label(self.stabilityschedule, text = 'Vials Per Time Point').grid(row = 0, column = 10)
        self.BackButton = ttk.Button(self.stabilityschedule, text = 'Back', command = self.Back)
        self.BackButton.grid(row = 26, column = 9)
        self.FinishedButton = ttk.Button(self.stabilityschedule, text = 'Finished', command = self.Finished)
        self.FinishedButton.grid(row = 26, column = 10)
        for x in range(1, 26):
            TimePointLabel = 'TimePointLabel' + str(x)
            TimePointLabel = ttk.Label(self.stabilityschedule, text = x)
            TimePointLabel.grid(row = x, column = 1)

            TimePoint = 'TimePoint' + str(x)
            TimePoint = ttk.Entry(self.stabilityschedule, width = 30)
            TimePoint.grid(row = x, column = 2) 

            VialsPerTimePoint = 'VialsPerTimePoint' + str(x)
            VialsPerTimePoint = ttk.Entry(self.stabilityschedule, width = 30)
            VialsPerTimePoint.grid(row = x, column = 10) 

        # Need to get the Check Box Text to be correct.  Right now they all say 60C
        StorCond = ['-20C', '5C', '25C', '30C', '40C', '50C', '60C']
        for x in range(1, 26):
            for y in range(3, 10):
                # for y in range(3, 10):
                StorageConditionsVar = 'StorageConditionsVar' + str(StorCond[y-3])
                StorageConditionsVar = BooleanVar()
                StorageConditions = 'StorageConditions' + str(StorCond[y-3])
                self.StorageConditions = ttk.Checkbutton(self.stabilityschedule, name = 'storageConditions' + str(StorCond[y-3]) + str(x),
                    text = str(StorCond[y-3]), variable = StorageConditionsVar, onvalue = True, offvalue = False)
                StorageConditionsVar.set(False)
                self.StorageConditions.grid(row = x, column = y)

                # print(self.StorageConditions.state())
    
    def Finished(self):
        print('Finished Button Clicked')
    
    def Next(self):
        # Moves to next tab in notebook
        self.notebook.select(1)
        # print(self.formulations.Formulation01.state())

    def Back(self):
        # Returns to first tab in notebook
        self.notebook.select(0)
    
    def print(self):
        print('Formulation Name: {}'.format(self.FormulationName01.get()))
        print('Formulation Selected: {}'.format(self.FormulationVar01.get()))

def main():            
    
    mainwindow = Tk()
    mainwindow.title('Stability Label Creator')
    app = Stability_Label_Creator(mainwindow)
    mainwindow.mainloop()

if __name__ == "__main__": main()

I some how need to find all the children text boxes on the Formulations frame in the note and determine which ones are checked.

Output:
Finished Button Clicked
