# Interface CarActionListener

public interface CarActionListener
Callback invoked when the user activates an in-car element -- a `CarRow`, `CarGridItem` or `CarAction`. Single-method, so application code on Java 8+ can supply it as a lambda. The callback is always delivered on the Codename One EDT.
