You are one smart guy! This helps a lot.
I can tolerate doing
LEnt = Entry(stuff stuff stuff)
LEnt.bind("<Return>", "call call call")
LEnt.bind("<KP_Enter>", on_kp_enter)
I can't really do the bind_class, because not all fields respond to a
Return/Enter.
What I'm trying to do is eliminate duplicating the "call call call" part like I
have now. Some/Most of the calls are kinda complex (a lot of argument passing
to the handlers). I'd seen that event_generate() a long time ago, but I never
figured out how to use it from the Grayson Bible. Now as I rescan that portion
of the book I realize you may have made me dangerous. :)
Thanks!
Bob
