You already link events to buttons so when you click on a button something happens. Now I need that when I click on an Entry element, I also link to an event. For example I have a date field in which by default I type "dd / mm / yyyy" and I want that when the user clicks in that field that text is deleted Thanks, best regards.

You just have to use the bind method of the widget of shift, in this case an Entry. The event that refers to the left click is '<Button-1>' :

import tkinter as tk

class App(tk.Frame):
    def __init__(self, root=None):
        tk.Frame.__init__(self, root)
        self.text = tk.StringVar()
        self.text.set("Escribe algo aquí...")
        self.entry = tk.Entry(bg='orange', textvariable=self.text, relief=tk.SUNKEN, width=50)
        self.entry.grid(row=0, column=0)
        self.entry.bind("<Button-1>", self.clear_entry)

    def clear_entry(self, event):
        self.text.set("")


if __name__ == "__main__":
     root = tk.Tk()
     app = App(root)
     app.mainloop()
