name 'set_hour' is not defined - python

Im working on this python code with tkinter. I would like to change the state of label set_hour to "active" by pressing 'j'. Everytime i run my code i get an error saying that set_hour is not defined. Do I need to use "self" here? and why can you explain please. Thank you
class SetClock:
def __init__(self, parent):
self.myParent = parent
self.current_datetime_label = tkinter.Label(root, text=datetime.datetime.now(), bg = "black", foreground="white").grid(row=1)
#current_time_label.pack()
self.menu_label = tkinter.Label(root, text="Menu", bg="sky blue", foreground="black",width=18).grid(row=2)
self.set_day = tkinter.Label(root, text="Set Day", bg="blue",foreground="white",width=9,state="active").grid(row=2, column=1)
self.set_hour = tkinter.Label(root, text="Set Hour",bg="blue",foreground="white",width=9).grid(row=2, column=2)
self.set_mintutes = tkinter.Label(root, text="Set Minutes", bg="blue",foreground="white",width=10).grid(row=2, column=3)
self.exit_label = tkinter.Label(root, text="Exit", bg="black", foreground="white").grid(row=2, column=4)
self.day_menu_label = tkinter.Label(root, text="Day",bg="sky blue",width=18).grid(row=3)
#menu_label.pack(side="right")
#current_time_label.pack()
def navigate_menu(event):
current_pressed = str(event.char)
print("pressed", current_pressed)
if current_pressed is 'j':
print("ok")
set_hour.config(state="active")
root = Tk()
#frame = Frame(root)
setclock = SetClock(root)
root.title("Set Clock")
root.minsize(width=500,height=500)
root.bind("<Key>",SetClock.navigate_menu)
root.mainloop()


You need to define navigate_menu as an instance method:
def navigate_menu(self, event):
current_pressed = str(event.char)
print("pressed", current_pressed)
if current_pressed is 'j':
print("ok")
self.set_hour.config(state="active")
When you bind it, pass bound method instead:
root.bind("<Key>", setclock.navigate_menu)
Also, separate Label creation line and grid() line. Otherwise, self.set_hour become None because grid() method return None.
self.set_hour = tkinter.Label(root, text="Set Hour",bg="blue",foreground="white",width=9)
self.set_hour.grid(row=2, column=2)


grid() returns None so you have to do
self.set_hour = tkinter.Label(...)
self.set_hour.grid(...)

retrieve selected value from a binded combobox in tkinter

I am trying to retrieve the selected value from a binded combobox.
In the below code, I have binded the combobox named “LSF_Combo” to another combobox “Queue _Combo” . I am trying to retrieve the selected value from the “Queue_Combo”, using Queue_Combo.get() method, but I am not able to do so, since its scope is limited within LSF_fields_Enable(event) inner function. I am able to retrieve the selected value of LSF_Combo using LSF_Combo.get() method.
Please let me know if anyone has suggestions for retrieving the selected value from the “Queue_Combo” combobox and furhter nested comboboxes "MT_Combo: and "Merge_Combo", so that I should be able to access and assign these to a variable outside the "LSF_Fields_Enable" function scope.
For example, If i had selected 'priority' from "Queue_Combo" and had selected "MT" from "MT_Combo", i should be able to assign these strings to variables outisde LSF_Fields_Enable(event) function. From the 'def run_program()' variable 'b' should have sting equals to 'priority' (since i have selected this) and variable 'c' should have string equals to 'MT'.

if __name__ == "__main__":
Gui_main()

There is not an easy way to fix this problem in your setup.
But the solution is easy, if you just go ahead and restructure your code a little:
Define the combobox outside the LSF_Fields_Enable function and also asign its values at startup.
Queue_Combo_list = ['normal', 'priority', 'devices', 'grid']
Queue_Combo = ttk.Combobox(root, values=Queue_Combo_list, width=10, state="readonly")
Now bind the ComboboxSelected Event to whatever function you want to have (in this example a simple print).
Queue_Combo.bind('<<ComboboxSelected>>', lambda _: print(Queue_Combo.get()))
And there you go!
Now the print function is executed every time the selection changes for the queue-combobox.
Hope this helps :)
EDIT:
In the updated Code below I reformated your code to make it more readable and to achieve what you wanted to have.
The Value of the ComboBoxes are now assigned to variables ("Queue_Combo_variable", "LSF_Combo_variable").
You can access their values using:
Queue_Combo_variable.get()
I tried my best to comment the entire to be as understandable as possible. Let me now if this is how you imagined it to be!

Python tkinter Radio Buttons "On Submit"

in my code I do not understand how radio buttons are working. My problem is, that the radio-buttons variables are not passed further.
from tkinter import *
class SimpleDialog(Frame):
def __init__(self):
super().__init__()
self.output1 = ""
self.output10 = ""
self.output11 = ""
self.output12 = ""
self.initUI()
def initUI(self):
self.master.title("New Input")
self.pack(fill=BOTH, expand=True)
frame1 = Frame(self)
frame1.pack(fill=X)
lbl1 = Label(frame1, text="Name:", width=20)
lbl1.pack(side=LEFT, padx=5, pady=10)
self.entry1 = Entry(frame1, textvariable=self.output1)
self.entry1.insert(0,"Your name")
self.entry1.pack(fill=X, padx=5, expand=True)
auswahl = IntVar()
auswahl.set(0)
frame10 = Frame(self)
frame10.pack(fill=X)
lbl10 = Label(frame10, text="Do you like tomatoes?", width=40)
lbl10.pack(side=LEFT, padx=5, pady=5)
self.entry10 = Radiobutton(frame10, text="No",variable=auswahl, padx = 0, value=0).pack(anchor=W)
self.entry11 = Radiobutton(frame10, text="Sometimes",variable=auswahl,padx = 0, value=1).pack(anchor=W)
self.entry12 = Radiobutton(frame10, text="Yes",variable=auswahl,padx = 0, value=2).pack(anchor=W)
frame3 = Frame(self)
frame3.pack(fill=X)
print(self.entry12)
btn = Button(frame3, text="New entry", command=self.onSubmit)
btn.pack(padx=5, pady=10)
def onSubmit(self):
# Input
self.output1 = self.entry1.get()
# Radio-Buttons
self.output10 = self.entry10
self.output11 = self.entry11
self.output12 = self.entry12
self.quit()
def main():
# This part triggers the dialog
root = Tk()
root.geometry("650x300+500+300")
app = SimpleDialog()
root.mainloop()
# Here we can act on the form components or
# better yet, copy the output to a new variable
user_input = (app.output1, app.output10, app.output11, app.output12)
try:
root.destroy()
except:
pass
return user_input
if __name__ == '__main__':
diaginput = main()
Can you help me to change the code, so that I can get the values of the radio buttons, e.g. print(diaginput).
I have problems to get the values of the radio buttons.

You should not try to access the radiobuttons but the variable you used to store the values.
But you should make the variable an attribute of the class of your dialog to access it from all methods:
self.auswahl = IntVar()
self.auswahl.set(0)
self.entry10 = Radiobutton(frame10, text="No",variable=self.auswahl, padx = 0, value=0).pack(anchor=W)
self.entry11 = Radiobutton(frame10, text="Sometimes",variable=self.auswahl,padx = 0, value=1).pack(anchor=W)
self.entry12 = Radiobutton(frame10, text="Yes",variable=self.auswahl,padx = 0, value=2).pack(anchor=W)
In the function on submit, you may then just get the value of the .auswahl attribute
# Radio-Buttons
self.output = self.auswahl.get()
The variable self.output will then hold an integer with a value between 0 and 2, depending on your selection.

How to restrict number of signs in Entry widgets with Tkinter

Hello i tried to do that in loop, but can't understand why only last created one is the only one restricted? I'd like to limit the 12 created widgets in loop to 4 signs. Can someone help me? :3
PS. Sorry if something uncleared, i ask question here for the first time.
from tkinter import *

self.wiersz+=1
self.var.append([])
self.iter+=1
if(self.wiersz<12):
self.map()
root = Tk()
b = Plansza(root)
root.mainloop()
[EDIT] I did a list but now I've got another error:
Whenever i wanna type something in my Entry widgets i got en error like this:
s = self.var[self.iter].get()
AttributeError: 'int' object has no attribute 'get'
And there are no more restrict number of sings even in last Entry widget.

(Answer to the question in your edit.)
In this line
s = self.var[self.iter].get()
it looks like you are trying to use get() to return an element of self.var. That is not how lists work. I'm pretty sure what you want is
s = self.var[self.iter]

An unexpected window appears in tkinter python

I made a separate file called clinic1.py for the other code and import it to the main page. Everything works fine however another window appears when I click save button on the add new item page.
When I place all the code on the main page that small window doesn't appear.
I cant find whats causing another window to appear when it's in a separate file.
This is my main page:

Both files have this line of code:
root = Tk()
Each time you do that, you get another root window. A tkinter application needs to have exactly one instance of Tk running at a time.
You need to remove the last two lines from clinic1.py. You will also need to pass in the reference to root to any methods from clinic1.py that need it.

Data Entry error

l would like to create a control system for administrator on Tkinter and some functions (add, delete, update and load) are main part of control system but when l run the code , these functions do not work and there is no error message. But ,l could not figure out where the problem is. My code is still not completed yet. İf l solve it, then l will move to another step.

It is bad practice to define your functions in a function and makes debugging pretty difficult. I would start by using an object to create this GUI. Object variables:
passwordVar and nameVar,
select
userlist
win

There's a lot going wrong for your code.
For instance, you don't need to import tkinter twice. Your casing of the variable names doesn't follow PEP8. You could benefit from an OOP approach.
I would suggest finding a good IDE to code in that can highlight your formatting and errors.
Take a look at the provided code:

["Prefect",'1345'],
["Zigler",'8910'],
['Smith','1298']]

Note:
There's still errors here, but I don't exactly know what you're trying to do so I've just restructured it here so you can start on a better path.
