禁用 TAB TKINTER python

Question

I am new to python and I am trying to disable TAB2 from widget notebook tkinter, through the support_test.py file I have the command of the disable_tab2 button, which should have the command to disable the option, but I get the error below:

Exception in Tkinter callback Traceback (most recent call last):   File

Answer 1

You must use the tab method to configure an individual tab, just like you're doing in some other places in your code. The first argument is a reference to the tab, such as the integer index of the tab. Following that is the state option with the desired value.

For example:

self.TNotebook1.tab(0, state="disabled")

Answer 2

I have made the following changes in the desativa_tab2() function inside of the teste_suporte.py file to disable the tab 2 in the notebook.

I used notebook_name.tabs() that will return a list of tab references in the notebook in order of first tab1, then tab2 and so on..

So, this notebook has two tabs and we want to disable the tab 2 therefore, grab the tab2 reference from the list of tabs at index 1.

tab2 = w.TNotebook1.tabs()[1]

Then select the tab2 from the notebook using notebook_name.tab() and then disable that very tab using the tab2 reference grabbed in the previous step

w.TNotebook1.tab(tab2, state='disabled')

Here is the complete desativa_tab2() function:

def desativa_tab2():
    global w

    tab2_name = w.TNotebook1.tabs()[1]
    w.TNotebook1.tab(tab2_name, state='disabled')

    print('teste_support.desativa_tab2')
    sys.stdout.flush()

Replace this function in your teste_suporte.py file. I tried to explain what changes I made with a bit of theory. Hope you understand!
