Hallo,
dafür gibtes -validatecommand option:
-validate => validateMode
Specifies the events that invoke the -validatecommand callback: none (default), focus, focusin, focusout, key, or all.
-validatecommand => callback
Specifies a callback that validates the input; undef disables this feature (default). The callback returns false to reject the new input and invoke the -invalidcommand callback or true to accept the input.
Gruß Alexander
