I'm trying to restrict keyboard input on given TextItem to signed integers by using the argument "[-+]?[0-9]+" in setKeyPressFilter method. But i cannot enter the '-' or '+' characters.

(The source code at http://www.smartclient.com/smartgwt/...eypress_filter at the second text item says only numeric values but someone can enter the dot '.')

The keypress filter is not not a full regular expression of the field format but a single expression to match each character against. So [0-9] would limit each character to a digit. Something like [0-9][a-z] would never work because only one character is matched against it at a time.

So, limit your keypresses to the valid characters that can be entered anywhere in the field and use a regex validator to confirm the overall value is correct.

Thanks for the explanation. I have already 'switched' to reg exp validators.
