Reading data files with ctk is pure frustration

[Heroeskeeper]

I have written Python script to read a data file using a given structure reference and index file and it works fine running from command prompt.
As soon as I try to apply a decent UI like ctk it all turns to crap. Now the data interpretation is corrupted. I simply copy pasted the extraction method into the ctk script.
My 2 front teeth for a decent python UI that can read data files as well as a bad UI does - a UI shouldn't affect the way a script reads a file.
Using classes makes things even worse, - this is supposed to make things easier!
Maybe I'm just green behind the ears. but logically, CTK is broken.

You've not really explained what you want to do or provided a minimum example.

I've no idea what you even mean by "but logically, CTK is broken." It has worked fine for all of the projects I've used it on.

Hi, apologies for my rant.
The code below:

import customtkinter as ctk

ctk.set_appearance_mode("dark")

word = ""

class Frame1(ctk.CTkFrame):
    def __init__(self, master, word):
        super().__init__(master)
        self.word = word

        self.name = ctk.CTkLabel(self, text="Name", fg_color="transparent")
        self.name.grid(row=1, column=0, padx=10, pady=10, sticky="w")

        self.name_x = ctk.CTkEntry(self, width = 300, placeholder_text="")
        self.name_x.grid(row=1, column=1, padx=10, pady=10, sticky="e")
        self.name_x.insert("end", self.word)
   
class App(ctk.CTk):
    def __init__(self):
        super().__init__()

        self.title("CRD Master")
        self.geometry("1000x650")
        self.grid_columnconfigure(0, weight=1)
        self.grid_rowconfigure(0, weight=1)

        self.acc_no = ctk.CTkEntry(self, width = 60, placeholder_text="Acc. no.")
        self.acc_no.grid(row=0, column=0, padx=10, pady=10, sticky="w")

        self.button = ctk.CTkButton(self, width = 60, text="get", command=self.button_callback)
        self.button.grid(row=0, column=0, padx=10, pady=10, sticky="e")

        frame = Frame1(self, word)
        frame.grid(row=1, column=0, padx=10, pady=(10, 0), sticky="nsw")

    def button_callback(self):
        word = "yay" 
        # Frame1.frame(word)
        # print(word)

app=App()
app.mainloop()

All I'm trying to do in this test code is display the word 'yay' in the ctkentry widget thats inside a ctkframe class.
There are no resources on the internet that shows how to use a ctkentry widget thats inside a ctkframe class to show information. It must surely be possible? Please help.

Do you want "yay" to appear as the default text in the ctkentry widget, or do you only want it to appear after the user has clicked the "get" button?

[Heroeskeeper]

After the user has clicked the 'get' button.

Ok so here is one solution that requires a small change of your code;

Note the following line:

self.frame = Frame1(self, word)

I don't know how experienced with python you are. If not very, then I would recommend to have a look at some material out there on classes and objects/object orientated programming to understand why that works.

Hope this helps!

import customtkinter as ctk

ctk.set_appearance_mode("dark")

word = ""

class Frame1(ctk.CTkFrame):
    def __init__(self, master, word):
        super().__init__(master)
        self.word = word

        self.name = ctk.CTkLabel(self, text="Name", fg_color="transparent")
        self.name.grid(row=1, column=0, padx=10, pady=10, sticky="w")

        self.name_x = ctk.CTkEntry(self, width = 300, placeholder_text="")
        self.name_x.grid(row=1, column=1, padx=10, pady=10, sticky="e")
        self.name_x.insert("end", self.word)
   
class App(ctk.CTk):
    def __init__(self):
        super().__init__()

        self.title("CRD Master")
        self.geometry("1000x650")
        self.grid_columnconfigure(0, weight=1)
        self.grid_rowconfigure(0, weight=1)

        self.acc_no = ctk.CTkEntry(self, width = 60, placeholder_text="Acc. no.")
        self.acc_no.grid(row=0, column=0, padx=10, pady=10, sticky="w")

        self.button = ctk.CTkButton(self, width = 60, text="get", command=self.button_callback)
        self.button.grid(row=0, column=0, padx=10, pady=10, sticky="e")

        self.frame = Frame1(self, word)
        self.frame.grid(row=1, column=0, padx=10, pady=(10, 0), sticky="nsw")

    def button_callback(self):
        word = "yay" 
        self.frame.name_x.insert(0, word)

app=App()
app.mainloop()

domhnallmorr you are a gentleman, thank you. I am a python newbie and will definitely take your advice. It works and I understand it better now.
