I can't seem to make my new window display the inputer code
it only displays a new empty window without the labels and the input widget
i want to make a simple GUI for a school project, but i dont want to type the name in the python shell, but in the interface

You must use your toplevel to indicate where the widgets must appear; you must also pack (place or grid) the widgets belonging to your toplevel window.
The code from inputer needed to be placed outside of the inner function; you can now write the code to have this inputer do what you need it to do:
I removed the star import and added the prefix tk. to all tkinter method calls.

I have some Radiobuttons. Depending of what Radio button was selected I want to have different Combobox values. I don't know how I can solve the problem. In a further step I want to create further comboboxes which are dependend on the value of the first.
The following code creates the list of user, but it does not show up in the combobox.
For me it is difficult to understand where the right position of functions is, and if I need a lambda function nor a binding.

This is to be a desktop application for opening multiple small databases and running queries on them. So far I've written some code for opening forms as necessary. Is this a good way to do it? Also - the code shown opens two copies of each form - what am I doing wrong? It's my first attempt at Python and I'm a rudimentary programmer so simple answers would be of most help please. TIA (Python 3.9.6)

I have two sets of code. One works the other doesn't and I don't know why. In the first set of code I am storing my application into a class and referencing everything there. In the second one I am storing everything in the main function and using it there.
The main details of the problem are here:
I am using a entry widget and a button widget which is initially disabled. I want the button's state to be normal when there is text in the entry widgets text field.
I have searched online for many answers to the first set of code but the closest I have gotten is the second set of code. First I tried to integrate it into my code however that did not work. So what I did was take the code and strip it to the bare minimum and put everything into the main function.
The main difference between the two is one is in a class and the other is in the main function.
import tkinter as tk
class Aplication(tk.Frame):
def __init__(self, master):
tk.Frame.__init__(self,master)
self.grid()
self.button_clicks = 0
something = tk.StringVar()
button3 = tk.Button(self, text="Print entry", padx = 10, height = 2, bg = "blue", state = "disabled")
entry = tk.Entry(self, textvariable = something)
something.trace('w', self.ActivateButton) #need this to always be exsecuted
entry.grid(column = 2, row = 1)
button3["command"] = lambda: self.PrintEntry(entry.get())
button3.grid(padx = 10, pady = 10)
def PrintEntry (self, entry):
print(entry)
def ActivateButton(self, *_):
if something.get():
button3['state'] = "normal"
else:
button3['state'] = "disabled"
if __name__ == '__main__':
top= tk.Tk()
top.title("Simple Button")
top.geometry("500x300")
app = Aplication(top)
top.mainloop()
def PrintEntry (entry):
print(entry)
def ActivateButton(*_):
if entry.get():
button3['state'] = "normal"
else:
button3['state'] = "disabled"
if __name__ == '__main__':
top= tk.Tk()
top.title("Simple Button")
top.geometry("500x300")
something = tk.StringVar()
button3 = tk.Button(top, text="Print entry", padx = 10, height = 2, bg = "blue", state = "disabled")
entry = tk.Entry(top, textvariable = something, bd = 2)
something.trace('w', ActivateButton)
entry.grid(column = 2, row = 3)
button3["command"] = lambda: PrintEntry(entry.get())
button3.grid(row = 3, column = 1, padx = 10, pady = 10)
top.mainloop()
There are no error messages; however you will find in the first set, the button's state never gets set to normal. Is there a way to do this for the first one? What is the difference between the two that makes it to where I can't enable the button in the first one if it is impossible?
You have to use self. to create class variables so they will be accesible in all methods in class. Currently you create local variable something in __init__ and it is deleted when Python ends __init__ - so finally it removes something.trace() and it doesn't check value in entry.
In this code I use self.something and self.button3 and it works correctly.
import tkinter as tk
class Aplication(tk.Frame):
def __init__(self, master):
tk.Frame.__init__(self,master)
self.grid()
self.button_clicks = 0
self.something = tk.StringVar()
self.button3 = tk.Button(self, text="Print entry", padx = 10, height = 2, bg = "blue", state = "disabled")
entry = tk.Entry(self, textvariable = self.something)
self.something.trace('w', self.ActivateButton) #need this to always be exsecuted
entry.grid(column = 2, row = 1)
self.button3["command"] = lambda: self.PrintEntry(entry.get())
self.button3.grid(padx = 10, pady = 10)
def PrintEntry (self, entry):
print(entry)
def ActivateButton(self, *_):
if self.something.get():
self.button3['state'] = "normal"
else:
self.button3['state'] = "disabled"
if __name__ == '__main__':
top= tk.Tk()
top.title("Simple Button")
top.geometry("500x300")
app = Aplication(top)
top.mainloop()
EDIT: the same little different - without lambda. I use self.entry (as class variable) directly in print_entry.
import tkinter as tk
class Aplication(tk.Frame):
def __init__(self, master):
super().__init__(master)#tk.Frame.__init__(self,master)
self.grid()
self.button_clicks = 0
self.something = tk.StringVar()
self.entry = tk.Entry(self, textvariable=self.something)
self.entry.grid(column=2, row=1)
self.button3 = tk.Button(self, command=self.print_entry, text="Print entry", padx=10, height=2, bg="blue", state="disabled")
self.button3.grid(padx=10, pady=10)
self.something.trace('w', self.activate_button) #need this to always be exsecuted
def print_entry(self):
print(self.entry.get())
def activate_button(self, *_):
if self.something.get():
self.button3['state'] = "normal"
else:
self.button3['state'] = "disabled"
if __name__ == '__main__':
top= tk.Tk()
top.title("Simple Button")
top.geometry("500x300")
app = Aplication(top)
top.mainloop()
As pointed out by #furas you need to prefix your variables in the constructor method def __init__ with self. so you can access attributes and methods since it literally represents an instance of the class. This link explains it in more detail https://stackoverflow.com/a/2709832/7585554.
import tkinter as tk
class Application(tk.Frame):
def __init__(self, master):
tk.Frame.__init__(self, master)
self.grid()
self.button_clicks = 0
self.something = tk.StringVar()
self.button3 = tk.Button(self, text="Print entry", padx=10, height=2, bg="blue", state="disabled")
self.entry = tk.Entry(self, textvariable=self.something)
self.something.trace('w', self.ActivateButton)
self.entry.grid(column=2, row=1)
self.button3["command"] = lambda: self.PrintEntry()
self.button3.grid(padx=10, pady=10)
def PrintEntry (self):
print(self.entry.get())
def ActivateButton(self, *_):
if self.something.get():
self.button3['state'] = "normal"
else:
self.button3['state'] = "disabled"
if __name__ == '__main__':
top = tk.Tk()

A simple quiz game
I got this code and I need scrollbars, I tried to search how to add it on stackoverflow (ScrolledWindow with tix...) but I still can't get something that works properly. Could someone help me?
from tkinter import *
from random import randint
root = Tk()
root.title("Quiz")
root.geometry("400x300")
class Window:
def __init__(self, question, answer):
self.text = [question, answer]
self.createLabel()
# self.createText()
self.createEntry()
self.createButton()
def retrieve_input(self):
# inputValue = self.textBox.get("1.0", "end-1c")
# print(inputValue)
if self.mystring.get() == self.text[1]:
print("Esatto. è " + self.text[1])
self.left['text'] = "Esatto"
def createLabel(self):
self.labelframe = LabelFrame(root, text="Domanda:")
self.labelframe.pack(fill="both", expand="yes")
self.left = Label(self.labelframe, text=self.text[0])
self.left.pack()
def createText(self):
self.textBox = Text(height=1)
self.textBox.pack()
def createEntry(self):
self.mystring = StringVar()
self.myentry = Entry(root, textvariable=self.mystring).pack()
def createButton(self):
self.but = Button(text="Click", command=self.retrieve_input)
self.but.pack()
for i in range(10):
one = randint(1, 10)
two = randint(1, 10)
Window("Quanto fa " + str(one) + "+" + str(two) + "?", str(one + two))
root.mainloop()
output
With ScrolledFrame it can look like this
I renamed Window into Question because it makes more sense
I use self.question and self.answer instead of self.text = [question, answer] to make it more readable.
I put classes and functions before root = tk.Tk() to make it more readable.
I use import tkinter as tk instead of from tkinter import * to make it more readable.
Question gets inner frame from ScrolledFrame and use as parent for LabelFrame. Other widgets use labelframe as parent.
BTW: you had entry = Entry(..).pack() which assign None to entry because pack()/grid()/place() returns None. I put pack() in next line and now I can get text directly from Entry (without StringVar)
Code
import tkinter as tk
from random import randint
# --- classes ---

def __init__(self, parent, vertical=True, horizontal=False):
super().__init__(parent)

self._vertical_bar.grid(row=0, column=1, sticky='ns')

So i have this code below. Ive tried a various form of how to get to work the StringVar, but nothing happened. And thats why a turned to you oh, god of stackoverflow. Pls show me how to make it throught. I have an input in Entry1 and I need to get this input into an sql ( ive cut it out because of its uninportant) and return the value of it and write it into Entry1 insted of the original input. Please Lord of SO halp me!

Update
I have to change in a way like that:
def callback(self):
#07561847
#tk()
atvevoText = StringVar()
number = self.entry1.get()
self.entry1.delete(0, 'end')
#self.entry1.insert(0, atvevoText)
self.entry1 = Entry(self, textvariable = atvevoText )
atvevoText = atvevo(number)
print(atvevoText)
*And with it i got nothing to back nor error nor the value :( *
Change
Frame.StringVar()
to
StringVar()
Since StringVar is a class inside Tkinter(not tested just googled)
