[Tkinter-discuss] ttk.Notebook: autohide

[Vasilis Vlachoudis]

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
Vasilis

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)
