Calling Tk->break from within your handler will prevent any further callbacks being called.

If the handler that you wish to supress is being called before your callback is processed, then you will need to either bind your callback at a higher level (say, to the class rather than the instance), or use $widget->bindtags to alter the order of the bindings.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
