Dominic Mayers <dominic_may...@yahoo.com> added the comment:
If it's normal, then the error message should perhaps be more informative and
user friendly than just a traceback:
Traceback (most recent call last):
File "./dialog.py", line 6, in <module>
integer_value = simpledialog.askinteger('Dialog Title', 'What is your
age?', minvalue=0, maxvalue=100)
File "/usr/lib/python3.7/tkinter/simpledialog.py", line 341, in askinteger
d = _QueryInteger(title, prompt, **kw)
File "/usr/lib/python3.7/tkinter/simpledialog.py", line 271, in __init__
Dialog.__init__(self, parent, title)
File "/usr/lib/python3.7/tkinter/simpledialog.py", line 137, in __init__
if parent.winfo_viewable():
AttributeError: 'NoneType' object has no attribute 'winfo_viewable'
If it is not too intrusive, it would be even more user friendly if the code
found some parent window.
