how to exclude the invalid inputs for the TextInput field

Hi All,

I have a set of invalid inputs. how to restrict those inputs form the user for my textInput field. I can use regExpValidator but that is for the list of valid inputs. my list of valid inputs contains more elements than invalid inputs. Is there any way to specify not to allow invalid inputs only. thanks in advance for your help :) :)

Create your own validator based on QValidator.
