Unbind initial bind on basic widget (text)

[Askari]

Hi,
Do I can unbind the initial bind on basic widget? (ex.: the basic widget
Text have the bind "<Control-a>" for the return to the first caracter of
the line; but me I don't want this!)
I try 'myText.unbind("<Control-a>")' but the bind is not remove.
:-(

N.B. I wan't disabled ALL initial bind (not just the "<Control-a>")

I see two options.

1. Prevent the event from being propagated to the class.

def breaker(*args):
return "break"

mytext.bind("<Control-a>", breaker)

2. Unbind the event on the class level.

mytext.unbind_class("Text", "<Control-a>")

Maybe you should just disable the widget?

mytext["state"] = "disabled"

You should probably read the Tk manpage on the bind and bindtags
commands.

If you want to get rid of all the normal bindings for a Text widget, you
can just do something like
tags = myText.bindtags()
tags.remove("Text")
myText.bindtags(tags)

If you want to stop only certain bindings, use the "break" technique
mentioned in another response to your post.
