Many thanks
The first solution works ok for me without any flickering
I think you are right it is a bug in tk, probably they forget
to invalidate the window

oh, I see. This "works" also vice versa here, the tab only reappears
after resizing the window with the mouse. Too bad, looks like a bug to me.

I am not sure how to do this, except with an ugly hack like:
def hidetabs(ev):
s.layout('TNotebook.Tab', [])
nb.pack(expand=0)
nb.update_idletasks()
nb.pack(fill='both', expand=1)
But that looks rather stupid and besides causes an annoying "flickering"
effect. The flickering seems to be a bit better with a "minimally
invasive" re-packing, as in
def hidetabs(ev):
s.layout('TNotebook.Tab', [])
info = nb.pack_info()
px = info['padx']
del info['padx']
nb.pack(padx=px + 1, **info)
nb.update_idletasks()
nb.pack(padx=px, **info)
but this looks somehow even more stupid.
But maybe I just miss something obvious?
Best regards
Michael
