If your GUI callbacks raise exceptions, the program may still function
correctly.
eg, basic Tkinter example (my Tkinter is a little rusty, so forgive errors):
#####
e = Entry(parent)
e.pack()
def clear():
e.delete(0, END)
raise ValueError
b = Button(parent, label='Clear', command=clear)
b.pack()
#####
The button will (I think) work correctly, and the program won't crash.
But you should see the exception printed to the command line (if you
run this program from a shell). I don't know for sure, but I imagine
the Tkinter mainloop() does something like:
try:
callback()
except:
# print trace to stderr
This is the only possibility I can think of at the moment. But there
could be other things going on, which is why we'd like to see an
example.
