ChrisA,
I'm always open to learning. There's no error generated ... yet the
application doesn' open so it's time to run it through pdb.
Spoiler: unless the name 'underline' is defined you get a NameError:
NameError: name 'underline' is not defined
If it is defined and self.callbacks is a dict you get a TypeError:
TypeError: unhashable type: 'slice'
because that's what a colon means in a context like
x[a:b]
From what you posted I would guess that underline is most likely a
keyword argument to the add_command() method:
file_menu.add_command(
label='New',
command=self.callbacks['file->new'],
underline=0,
accelerator='Ctrl+N'
)
