Hello, @ Michael Lange : thank you for the keyword : state='readonly'. This is what I needed. It doesn't show in any of the general documentation I had on Tkinter, but it is indeed in the Tk man page of the "Entry" widget. @ Michael O'Donnell :

The original poster should note that every time you want to change the text displayed, you need to change the state to normal, change the text, and then re-assert state='readonly'.

In fact I am using a "textvariable" link, so I don't need to do this. Regards, O.C. Créez votre adresse électronique prenom.nom@laposte.net 1 Go d'espace de stockage, anti-spam et anti-virus intégrés.
