Hi all,
during the filling of a ttk.Treeview, widget I want to temporarily disable the
<<TreeviewSelect>> (to restore the previously selected items), and re-enable it
at the end.
However, when I unbind the <<TreeviewSelect>> event the messages are still
send. See the following demo code. I would expect that during the filling no
<<TreeviewSelect>> message will be send, however I get hundreds of messages at
the end
import tkinter as tk
from tkinter import ttk
def tvselect(event):
print("SELECTION CHANGED")
def fill(event=None):
t.unbind("<<TreeviewSelect>>")
for i in range(1000):
item = t.insert("",tk.END,text=f"Item {i}")
if i&1==0: t.selection_add(item)
t.bind("<<TreeviewSelect>>", tvselect)
if __name__ == "__main__":
root = tk.Tk()
t = ttk.Treeview(root)
t.bind("<<TreeviewSelect>>", tvselect)
t.pack(expand=tk.YES,fill=tk.BOTH)
b = tk.Button(root, text="Press me", command=fill)
b.pack()
root.mainloop()
