This commit enhances the SCXML Editor by adding a new feature that enables the display of onEntry and onExit events in the state item. This feature provides developers with a more comprehensive view of the state machine's behavior, allowing them to better understand the transitions that occur when entering or exiting a particular state. Fixes: QTCREATORBUG-17378 Change-Id: Iaf84af209d9acf13bd4183f7da9acbcd6c1c8214 Reviewed-by: Alessandro Portale <alessandro.portale@qt.io>
