Using theme with Tabs - Performance issue

[kobi-adler]

After I added tabs to my app with the theme activated I started to experience performance issues.

Also, the tabs and menu bar don't have any visual effect from the theme.

But I really like your Dark theme so keep going :)

First of all thank you for trying my theme!

Tab

Did you mean notebook?

It should work with the theme
Try this code:

notebook = ttk.Notebook(root)
notebook_tab1 = ttk.Frame(notebook, width=200, height=200)
notebook.add(notebook_tab1, text='Tab 1')
notebook_tab2 = ttk.Frame(notebook, width=200, height=200)
notebook.add(notebook_tab2, text='Tab 2')
notebook_tab3 = ttk.Frame(notebook, width=200, height=200)
notebook.add(notebook_tab3, text='Tab 3')
notebook.pack()

Menubar

Unfortunately the theme can only change the appearance of ttk widgets, not the simple tkinter widgets, so only the foreground and background colors of the menubar submenu can be changed.
