Examples of org.apache.pivot.wtk.validation.Validator

org.apache.pivot.wtk.validation.Validator
Validation interface for text components. Allows the programmer to specify constraints on text data.
This is indicated visually to the user (a red background would be typical), and events are fired by the TextInput if the programmer wishes to take further action.

        textinputCustomBoolean.setText("true");
        textinputCustomBoolean.setValidator(new Validator() {
            @Override
