Récupérer le texte dans une zone de texte tkinter

Bonjour, je suis en plz
après avoir essayé plusieurs heures (oui… X) de relier deux programmes python Tkinter, je m'en remet à vous. Voila mon problème, j'ai une fonction (trouvé sur le net), qui me permet de faire une zone de texte arrondie sur Tkinter. J'ai besoin de récupérer le texte que j'inscris dans cette dernière, mais elle n'est pas définie comme entry box… J'ai donc galéré à faire un programme (séparément) qui me permet de récupérer chaque touche appuyé avec bind dans une liste L. Mais quand je relie les deux entre eux ils ne fonctionnent pas et je voudrais savoir comment faire… Le reste du programme vise à créer plus tard une interface de calendrier mais c'est pas important.

import tkinter as tk

from tkinter import ttk

Je suis désolé c'est très fouillis et mal syntaxé mais je ne suis pas très bon... MERCI D'AVANCE !
ps: le module Tkinter m'est imposé
