Whenever I get an error in my Tkinter application, I would like to get a full stack trace of where the error occurred, through all of the functions the program is currently in.
Before my root window opens, I have Tk.report_callback_exception = TKINTERERROR and I am able to get the traceback object of the error in TKINTERERROR(). However, when I attempt to print the traceback (with traceback.format_list(traceback.extract_tb(tracebackObject))), it only gives me the most recent function call, and the line the error occurred on. Is this all that is possible with Tkinter exceptions, or is there a way to get the entire stack trace?
To elaborate, what I expect to get is something like this, in which all the functions the program is currently in are given:
Traceback (most recent call last):
File "myfilepath", line 13, in <module>
func1()
File "myfilepath", line 2, in func1
func2()
File "myfilepath", line 5, in func2
func3()
File "myfilepath", line 8, in func3
func4()
File "myfilepath", line 11, in func4
0/0
ZeroDivisionError: division by zero
However, I actually only get this:
File "...Python311\Lib\tkinter\__init__.py", line 1948, in __call__
return self.func(*args)
^^^^^^^^^^^^^^^^
File "myfilepath.py", line 1898, in <lambda>
widgetMethod(arguments, command = lambda: MyFunction(arguments))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "myfilepath", line 2465, in MyFunction
0/0
~^~
My problem is that I would like to get the full stack trace, but I am only given the most recent function called.
This can be done by redefining the default TKINTERERROR() function:
from tkinter import *
import traceback
Tk.report_callback_exception = TKINTERERROR
#These arguments are supplied automatically and must be here
def TKINTERERROR(tkinterLibrary, errorClass, finalErrorMessage, tracebackObject):
'''Prints stack trace of Tkinter error and enters Python debugger.'''
print('\n' + str(errorClass) + ':\n' + traceback.format_exc() + '\n' + str(finalErrorMessage) + '\n')
import pdb; pdb.post_mortem(tracebackObject)
