How to detect a selected text using python?

Question

I'm looking for a way to copy a selected text in a tkinter.scrolledtext and paste it automatically in an Entry.

Means, Every time a user selects a text it will be added to the tkinter Entry automatically.

Any suggestions? specially on how to get the selected text.

Answer 1

You can use the selection event generated from text widget to add to your entry widget.

import tkinter as tk
from tkinter import scrolledtext as tkst

root = tk.Tk()

txt = tkst.ScrolledText(root)
txt.insert(tk.END, "This is a test phrase")
txt.pack()

entry = tk.Entry(root)
entry.pack()

def select_event(event):
    try:
        entry.delete(0, tk.END)
        entry.insert(0, txt.get(tk.SEL_FIRST, tk.SEL_LAST))
    except tk.TclError:
        pass

txt.bind("<<Selection>>", select_event)

root.mainloop()
