Read only text widget in python3-tkinter; cross platform

Question

How to suppress the ability of the end user to edit / add / delete text in a text widget? (Python v3.2 .. and tkinter)

The fact is that it only suppresses the ability to change / add / delete text , but not to castrate other functions. Perhaps a better name would be NoEdit Text widged.

I tried .text ['state'] = 'disabled' and it works almost normally on Windows (it still allows the user to select / copy text, selects the highlight, up / down pages and up / down buttons. The only thing that is broken, seems to be an invisible cursor.)

But on MacIntosh, everything is broken. No backlight, no selection / copy, ... UGH

Since Tkinter has virtually no Python documentation, I searched and found some TCL tips to get a new class and suppress insert and delete functions .

So, I tried like this:

class roText(tk.Text):
    def insert(self,*args,**kwargs):
        print(" Hey  - Im inside roText.insert")
        pass
    def delete(self,*args,**twargs):
        pass    
    def pInsert(self,*args,**twargs):
        super().insert(*args,**twargs)

Unfortunately, this did not work. Apparently, tkinter does not use these functions insert and remove, when the end user adds / removes the code. Perhaps these TCL insertions / deletions are something else, and I lost something translated from TCL and Swahili. What features does tkinter.Text use to edit text for the end user? Hope they are not internal ...
