Click event before value change. (Checkbox)

Using CheckBox and need to pop up a dialog BEFORE the check is set or unset. What listener should I use? Is there a previous value stored somewhere?

There is a variety of listeners on the CheckBox component.

If you use addValueChangeListener you'll get a ComponentValueChangeEvent On this event, you can get the old value.
