Enable validation of keys typed in AbstractStringField [message #631717]

SwtScoutStringField should propagate every SWT-Event of event type SWT.KeyUp to the setTextFromUI(String) method of P_UIFacade of the AbstractStringField (analogous for KeyEvents in Swing). That would enable a programmer to validate text input on every key typed, for example by overriding the execIsEmpty() method of AbstractValueField. Currently only a validation after a traversal is possible, which is sometimes not so convenient for the user.

Hi Jens

You are right, a validation on every key typed would be helpful in some circumstances. Fortunately it is already possible. Smile

You only have to enable it by setting the property validateOnAnyKey on your string field to true.

@Override
protected boolean getConfiguredValidateOnAnyKey(){
  return true;
}

This will execute execValidate on every key typed.

Regards
Claudio
