We could adjust any of these in our scripts using something like this script, where we disable a text box (the text box will display, but the user cannot enter a value into it). We could have the following script:

from ipywidgets import * 
Text(value='You can not change this text!', disabled=True) 

This is the screenshot of the preceding code:

When a field is disabled, the textbox is grayed out. When the user hovers the cursor over the field, they get a red circle with a slash through it, which means it cannot be changed.
