python - How do I get an event callback when a Tkinter Entry widget is modified? -


exactly question says. text widgets have <<modified>> event, entry widgets don't appear to.

add tkinter stringvar entry widget. bind callback stringvar using trace method.

from tkinter import *  def callback(sv):     print sv.get()  root = tk() sv = stringvar() sv.trace("w", lambda name, index, mode, sv=sv: callback(sv)) e = entry(root, textvariable=sv) e.pack() root.mainloop()
