Implementing Textitem maximum width in Smart GWT 2.6

Question

At Smartgwt, I’m trying to make a MaxLength in a TextItem. This TextItem is in an editable field of a Grid. Below follows the code used.

How to do a validation on OnKeyPress which, when it reaches the established limit, does not allow the user to enter any more characters?

    final TextItem editorType = new TextItem();
    editorType.setLength(100);
    editorType.setEnforceLength(true);
    editorType.setValidateOnChange(true);
    editorType.addKeyPressHandler(new KeyPressHandler() {
        @Override
        public void onKeyPress(KeyPressEvent event) {
            if(editorType.getValue().toString().length() > 100)
                event.cancel();
        }
    });
