Callback function that resets entry fields

[gm43287]

I'm using CustomTkinter version 5.2.2. and Python 3.12.

What is the best way to do this? I have a frame that will contain a variable number of input fields depending on some other code that isn't relevant here. The entry data is contained in global StringVar's. I have a callback function that needs to redraw the entry fields and clear out their contents. The code works, but spits out a bunch of internal errors when it has to redraw the entry fields. I've created a tiny program that demonstrates the error the second time the redraw button is clicked.

import customtkinter as ctk

def redraw():
    for w in dataframe.winfo_children():
        w.destroy()
    field1_var.set('')
    ctk.CTkEntry(dataframe, width=50, textvariable=field1_var).pack()

mainwin = ctk.CTk()

field1_var = ctk.StringVar()

dataframe = ctk.CTkFrame(mainwin)
dataframe.pack()
buttonframe = ctk.CTkFrame(mainwin)
buttonframe.pack()

ctk.CTkButton(buttonframe, text='Quit', command=mainwin.destroy).pack()
ctk.CTkButton(buttonframe, text='Redraw', command=redraw).pack()

mainwin.mainloop()

Hi,
it is a bug, already reported here, and fixed here.
As reported in this discussion, you can find version 5.3.0 with the fix under a new name: Custom2kinter.

You can avoid the bug by calling pack_forget() instead of destroying the children.
