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()

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):

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

You did not provide the code that produces the error.
You want to use winfo_children(). findChild is from Qt (and maybe otheres), not tkinter.
The easiest and most obvious answer to your dilemma is keep the reference to the check boxes (or better yet the BoolVar that is bound to the check box value). Then you don't have to search.

I have seen one way is to create a dictionary and save the name as key and an IntVar as value, the checked box is 1.
here's a rewrite of your code hope it points you on path to success:
from tkinter import *
from tkinter import ttk
class Stability_Label_Creator():
def __init__(self, master):
self.notebook = ttk.Notebook(master)
self.notebook.pack()
self.checkbuttons= {}
# 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)
value_= IntVar()
self.checkbuttons[FormulationVar]= value_
self._Formulation = 'Formulation' + str(x)
self._Formulation = ttk.Checkbutton(self.formulations, text = FormulationVar, variable = value_,
)
self._Formulation.grid(row = x, column = 2)
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)

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),

StorageConditionsVar.set(False)
self.StorageConditions.grid(row = x, column = y)
# print(self.StorageConditions.state())
def Finished(self):
print('Finished Button Clicked')
for key,value in self.checkbuttons.items():
if value.get():
print(key) #prints the name of the checked box
def Next(self):
# Moves to next tab in notebook
self.notebook.select(1)
def Back(self):
# Returns to first tab in notebook
self.notebook.select(0)
def main():
