3 years ago Hello Bruno, thanks for trying pygubu.
I am trying to disable menus programmatically. In pygubu-designer I am able to adjust the state variable from normal to disabled to achieve what I want, but when I try to programmatically make the change, i.e. self.builder.get_object('menuItem').configure(state='disabled'), I get an error stating that tkinter.TclError: unknown option "-state"
When you do:
self.builder.get_object('menuItem')pygubu will return the tk.Menu associated to that item. Once you have the menu, you can manipulate its items, using the entrycget and entryconfigure methods. Note that menu item manipulation uses indexes. More info here Here is a simple example. Let me know if you have more questions.
Regards Alejandro A.

If I can change this option within pygubu-designer, why am I not able to change it within the code of my application? If I am able to change it within the code of my application please inform me of how.
Thanks, B
