How to catch the clipboard event (onChangeClipboard equivalent) from any application in Python

Question

I am working on a clipboard manager. My current issue is to succeed in catching modification of the clipboard from any applications. For instance :

• From a ctrl - c
• From a right click and copy to clipboard

The idea is that a python script is running in background, like a deamon and catch every change of the clipboard

Thank you a lot :)

PS: For people who know autohotkey, I am looking for onClipboardChange equivalent

I found in the web a solution using GTK:

from gi.repository import Gtk, Gdk

def callBack(*args):
    print("Clipboard changed. New value = " + clip.wait_for_text())

clip = Gtk.Clipboard.get(Gdk.SELECTION_CLIPBOARD)
clip.connect('owner-change', callBack)
Gtk.main()
