Tk::Text listening to a tag covering 1.0 to end stops working after clearing all text (on Mac) about tk HOT 4 CLOSED

I reported at the ActiveState Community Forum (not sure where else to report):

from tk.

OK, good news! It is not Ruby's fault! I recreated the same exact problem with Python and TKinter:

from tkinter import *
from tkinter import ttk

root = Tk()

text = Text(root)
text.grid()
text.insert('1.0', "Some giberish\nMore giberish\nNot well spelled giberish")
text.tag_add('all', '1.0', 'end')
def print_info(event):
  print('key press')
  print(event)
  
text.tag_bind('all', '<KeyPress>', print_info)

root.mainloop()

from tk.

I tried your example ruby program and can reproduce the issue using tk-8.5.19 on OpenBSD. So it doesn't appear to be specific to ActiveState's distribution, it's probably an issue in tk itself.

Since this doesn't appear to be a bug in ruby-tk, I'm going to close this now.

For those who may be interested to know, I would like to note that I reported this as an official Tcl/Tk issue: https://core.tcl-lang.org/tk/tktview/631a0b2d95b8426a8851829b16a9d77b9f79b03e
