ok sorry. As another alternative I had thought of this:
from tkinter import *
from tkinter.ttk import *
root = Tk()
t = Treeview(root)
t.insert('', 0, iid='item1', text='item1')
t.insert('', 1, text='item2')
t.tag_configure('flashtag', background='red')
t.pack()
style = Style()
styleDefault = (style.map("Treeview"))
def flash():
tags = t.item('item1', 'tags')
t.item('item1', tags='' if tags else 'flashtag')
t.after(500, flash)
itemselected = t.selection()
for x in itemselected:
if (x == 'item1'):
style.configure('Treeview', selectbackground='red')
style.map('Treeview', background=[('disabled', 'white')],
foreground=[('disabled', 'red')])
else:
style.map('Treeview', background=[('selected',
styleDefault['background'][1][1])],
foreground=[('selected',
styleDefault['background'][0][1])])
flash()
mainloop()
Maybe it can be useful for other situations.
Bye bye
