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)

This is a bit late, but if you still need to capture ctrl-c:
here's the general way to capture ctrl-c within a python script.

• 1st add import signal at top of script.
  
• somewhere near the (logical) start of your program, add:
  signal.signal(signal.SIGINT, self.capture_ctrl_c)
  
• Add a function:
  

  def capture_ctrl_c(self, sig, frame):
      print('User interrupt encountered\nAdd your ctrl-C code here')
      ...

I know how to capture ctrl-c. It's right-click copy I need too.

The issues above I fixed exceptr the right-click copy

You will have to create your own event binding for this.
Download John Shipman's tkinter manual here
go to page 158 and read the section 54.2 to learn how to do this.
