Tkinter Entry widget issue

Question

Why am I getting this error when trying to insert into an Entry box in Tkinter?

File "/usr/lib/python3.10/tkinter/__init__.py", line 3085, in insert

    self.tk.call(self._w, 'insert', index, string)
_tkinter.TclError: invalid command name ".!toplevel.!labelframe.!entry"

This is my code:

_w2.dbEntry.insert(END, "Hello")

I have tried everything, but I cannot understand why. Please advice.

Answer 1

The toplevel or label frame doesn't exist. You haven't shown enough code, but you are either destroying one of those widgets or you never created them prior to inserting text.
