Is there any recommendation which tkinter calls have to be protected with an
exception handling
I occasionally receive traceback errors from my users on various calls
like: grab_current, grab_release, focus_get
most of the times I protect them with with a TclError handler catching
exceptions
like_tkinter.TclError: bad window path name
Also which type of exception has to be protected, this is the first time I've
got a KeyError
from a tkinter call, which normally should be innocent focus_get()"
Traceback:
Traceback (most recent call last):
File "/usr/local/flair/tkFlair.py", line 1304, in __call__
return self.func(*args)
File "/usr/local/flair/InputExtra.py", line 1026, in focusOut
self._focus = self.focus_get()
File "/usr/lib/python3.8/tkinter/__init__.py", line 748, in focus_get
return self._nametowidget(name)
File "/usr/lib/python3.8/tkinter/__init__.py", line 1498, in nametowidget
w = w.children[n]
KeyError: '__tk__messagebox'
