Question

I'm having a simple tkinter two frame application with a Label, Entry and Button widget and I want to access a StringVar() of FrameOne with a Entry and Button of FrameTwo.

If have seen a lots of examples of code, but do not get how this is been done in my example below. Many programmers are using a controller. If I would use a controller, I end up from an error to another. For example:

FirstFrame = FrameOne(mainWindow)`

TypeError: __init__() missing 1 required positional argument: 'controller'

Which I completely understand, because I do not pass anything into the new 'controller' class argument when calling the Frame class. But I do not know what I should pass into this to solve it. Perhaps it is also caused by the lack of knowledge of using class variables (any literature tips are welcome).

The same counts for the solution to inherit FrameOne into FrameTwo. I bump into the same amount of errors applying to my code.

Another thing is that many programmers have examples of two frames that are not visible at the same time, while in my example I have two frames underneath each other at the same time.

An different related issue that I have is, what if the label widget of FrameOne was a Text widget? How do I access the widget from FrameTwo.

I could make it work with globals, but I do not want to use such writing and I will keep the access widget problem anyhow.

Please find my code below:

import tkinter as tk

class AppWindow():
    def __init__(self, master):
        self.master = master
        master.title("Test Application")
        master.geometry("1060x680")
        master.grid_propagate(False)


class FrameOne(tk.Frame):
    def __init__(self, parent):
        super().__init__()
        self["borderwidth"]=5
        self["relief"]="ridge"

        self.LabelText = tk.StringVar()
        self.LabelText.set("It is not working yet")

        self.testlabel = tk.Label(self, textvariable=self.LabelText)        
        self.testlabel.grid(row=1, column=1)


class FrameTwo(tk.Frame):
    def __init__(self, parent):
        super().__init__()
        self["borderwidth"]=5
        self["relief"]="ridge"

        self.testentry = tk.Entry(self)
        self.testentry.insert("end", "This should be working")
        self.testentry.grid(row=1,column=1)

        self.testbutton = tk.Button(self, text="Test the label", command=self.updatelabel)
        self.testbutton.grid(row=1,column=2)

    def updatelabel(self):
        FrameOne.LabelText.set(self.testentry.get())   #HOW TO FIX THIS CODE THE RIGHT WAY?


#Create a window as defined in the AppWindow class
mainWindow = AppWindow(tk.Tk()) 

#Create a Frame as defined in class FrameOne
FirstFrame = FrameOne(mainWindow)
FirstFrame.grid(row=0, column=0) #Positioning Frame on Window

#Create a Frame as defined in class FrameOne
SecondFrame = FrameTwo(mainWindow)
SecondFrame.grid(row=1, column=0) #Positioning Frame on Window

Solution

I think that your configuration is OK.

The solution could be to configure the option that stop to seed files when they are completed.

Go to configuration option of the Download Station, menu BT, in the section "Stop Task Automatically", and in the second combo box (propagating time...) select "Forever".

What does happen when you click the button?

@martineau: I wish you wouldn't recommend that code to beginners. It's terrible as a learning tool, and has led to countless questions on this site.

Does this answer your question? how-would-i-access-variables-from-one-class-to-another

Unfortunately, it doesn't. I have read it and it inheritates one class into another. But in my code I already inheritating the tk.Frame. I get an error when I inheritate another class. In my test example, Brian provided me the simples, but correct answer (below).

Thanks a lot. How could I have missed this... Thank you for the PEP8 too.
