Keyboard history program

[chesschaser]

Hi guys!

I've been making a keyboard history program called ClipboardHero in python which stores your last clipboard entries in a file. I have encountered two problems while making this program:

• I need the Ctrl-C keys to activate the program even when the window is not in focus
  
• I need it to activate not only with Ctrl-C but with right-click+Copy as well
  

I would grateful if anyone could help!

The code:

from tkinter import *
from tkinter import messagebox
import winsound

subMenu = Tk()
subMenu.title("ClipboardHero")
subMenu.attributes("-topmost", True)
subMenu.overrideredirect(True)
subMenu.withdraw()

menuShown = False

clipboardSaves = open("clipboard.txt", "a")
clipboardSaves.close()

def copy():
    global menuShown
    clipboard = str(subMenu.clipboard_get())

    clipboardSaves = open("clipboard.txt", "a+")
    clipboardSaves.write("\n" + clipboard)
    clipboardSaves.close()

    messagebox.showinfo("ClipboardHero - Clipboard saved", "Your current clipboard has been saved!\n" + clipboard)
    menuShown = False
    subMenu.withdraw()

def hideMenu():
    subMenu.withdraw()
    menuSHown = False
    
def showMenu(event):
    global menuShown
    
    if menuShown == False:
        winsound.Beep(400, 300)
        winsound.Beep(600, 300)
        
        subMenu.deiconify()

        Label(subMenu, text = "Do you want to copy this text to ClipboardHero?").grid(row = 0, column = 0)

        yes = Button(subMenu, text = "Yes", width = 50, bg = "green", command = copy)
        yes.grid(row = 1, column = 0)

        no = Button(subMenu, text = "No", width = 50, bg = "red", command = hideMenu)
        no.grid(row = 2, column = 0)

        menuShown = True
        subMenu.mainloop()

subMenu.bind("<Control-c>", showMenu)
