With an old and slow laptop of mine the flickering effect appears to be a bit worse than on my desktop machine. Changing only the padx by one pixel seems to cause only a slightly "trembling" effect that is hardly noticable at all, so I guess the second workaround might be a bit better. (Maybe calling those workarounds "stupid" the other day was a bit harsh, if there's actually nothing better the second version might be not so bad) > > I think you are right it is a bug in tk, probably they forget > to invalidate the window Still I am not sure if I didn't miss something here. I think one bad thing about ttk is that the more advanced operations on styles and themes aren't really documented very well, so I always find it hard to find out how to do things properly, I always end up with some try-and-error solution.

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

Re: [Tkinter-discuss] ttk.Notebook: autohide
Many thanks Michael.
The recipe works the tab bar disappears (and reappears), but the space of the
tabs is not reclaimed.
the child-window is not resized to get the extra space.
If I resize the toplevel window with the mouse then it works.
Is there a way to force the layout manager to recalculate all widgets?
Best regards

it seems you can show or hide the tabs with something like:
s=ttk.Style()
# store default layout options
tablayout = s.layout('TNotebook.Tab')
# hide tabs
s.layout('TNotebook.Tab', [])
# show tabs again
s.layout('TNotebook.Tab',tablayout)
