管理ttk.Notebook中的选项卡（启用，禁用等）

Question

I'd like to know how to change the state of a tab in a ttk.Notebook after it's creation and how to manage multiple tabs properly.

Example:

import Tkinter as tk
import ttk
from myWidgets import Widget1, Widget2, Widget3

def enableTabs(notebook):
    tabs = notebook.tabs()
    for i, item in enumerate(tabs):
        item['state'] = 'enabled' #This doesn't work
        item.configure(state='enabled') #Doesn't work either
if __name__ == '__main__':
    root = tk.Tk()

    notebook = ttk.Notebook(root)

    w1 = Widget1()
    w2 = Widget2()
    w3 = Widget3()

    notebook.add(w1, text='tab1', state='disabled')
    notebook.add(w2, text='tab2', state='disabled')
    notebook.add(w3, text='tab3', state='disabled')

    enableTabs(notebook) #This would be called upon certain events in the real     application

    root.mainloop()

In this example I use disable - enable but in general I'd like to be able to change certain settings all at once.

What you call item is just an identifier (a float), which doesn't have a state key or a configure method. Also, the possible values for a tab's state in this context are normal , disabled and hidden , not enabled . Try this instead:

for i, item in enumerate(tabs): 
    notebook.tab(item, state='normal') # Does work
