Salut,

Tkinter ne possédant pas de menu contextuel pour les actions "copier/coller et couper", j'ai créé une petite classe à partir de différents exemples trouvés sur le net.

Merci vos retours et améliorations.

Code :

import tkinter as tk
import platform


class ContextMenuWidget(tk.Menu):
    """Extended widget with a context menu that includes Cut, Copy, and Paste commands."""

    def __init__(self, widget: tk.Widget, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self.widget = widget
        self.config(tearoff=False)

        self.add_command(label="Couper", accelerator="Ctrl+X", command=self.popup_cut)
        self.add_command(label="Copier", accelerator="Ctrl+C", command=self.popup_copy)
        self.add_command(label="Coller", accelerator="Ctrl+V", command=self.popup_paste)
        self.add_separator()
        self.add_command(label="Tout sélectionner", accelerator="Ctrl+A", command=self.select_all)

        self.map_right_button_event()

        self.widget.bind("<<RightClick>>", self.show_menu)
        self.widget.bind("<Control-a>", self.select_all)
        self.widget.bind("<Control-A>", self.select_all)

    def map_right_button_event(self):
        if platform.system() == "Darwin":
            self.event_add("<<RightClick>>", "<Button-2>")
        else:
            self.event_add("<<RightClick>>", "<Button-3>")

    def update_menu_state(self):
        if isinstance(self.widget, tk.Text):
            widget_content = self.widget.get("1.0", tk.END).strip()
        else:
            try:
                widget_content = self.widget.get()
            except AttributeError as error:
                print(error)
                return False

        clipboard_content = self.widget.clipboard_get()
        content_available = bool(widget_content)

        self.entryconfig("Couper", state="normal" if content_available else "disabled")
        self.entryconfig("Copier", state="normal" if content_available else "disabled")
        self.entryconfig("Coller", state="normal" if clipboard_content else "disabled")
        self.entryconfig("Tout sélectionner", state="normal" if content_available else "disabled")

        return True

    def popup_cut(self):
        self.widget.event_generate("<<Cut>>")

    def popup_copy(self):
        self.widget.event_generate("<<Copy>>")

    def popup_paste(self):
        self.widget.event_generate("<<Paste>>")

    def show_menu(self, event=None):
        if self.update_menu_state():
            self.tk_popup(event.x_root, event.y_root)

    def select_all(self, event=None):
        self.widget.event_generate("<<SelectAll>>")
        return "break"


root = tk.Tk()

label_entry = tk.Label(root, text="Entry Widget : ")
label_entry.grid(column=0, row=0, sticky="w")

widget_entry = tk.Entry(root, width=31)
widget_entry.grid(column=1, row=0, sticky="w")
ContextMenuWidget(widget_entry)

label_text = tk.Label(root, text="Text Widget : ")
label_text.grid(column=0, row=1, sticky="wn")

widget_text = tk.Text(root, height=13, width=31, wrap=tk.NONE)
widget_text.grid(column=1, row=1, sticky="w")
ContextMenuWidget(widget_text)

vertical_scrollbar = tk.Scrollbar(root, orient=tk.VERTICAL)
vertical_scrollbar.grid(column=2, row=1, sticky="ns")
widget_text.config(yscrollcommand=vertical_scrollbar.set)
vertical_scrollbar.config(command=widget_text.yview)

horizontal_scrollbar = tk.Scrollbar(root, orient=tk.HORIZONTAL)
horizontal_scrollbar.grid(column=1, row=2, sticky="we")
widget_text.config(xscrollcommand=horizontal_scrollbar.set)
horizontal_scrollbar.config(command=widget_text.xview)

root.mainloop()
