Chapter 5 Building Dynamic Diagrams
The Trigger tab in the transition property sheet comprises the following properties. It is visible for all transitions but editable only for transitions in statechart diagrams:
| Property | Description |
|---|---|
| Trigger event | Read-only list listing all events in the package. It specifies the event that triggers the transition. You can click the Properties tool beside this box to display the event property sheet. It is available only for transitions coming from a state or a start and is not editable in other cases. When you define a trigger event, the inverse relationship is displayed in the Triggered Objects tab of the corresponding event property sheet. The Triggered Objects tab lists transitions that the event can trigger.
For more information on events, see "Events". |
| Event arguments | Arguments of an event defined on a transition. You can specify a list of event arguments (arg1, arg2,...) in this box |
| Trigger action | Specifies the action to execute when the transition is triggered.
For more information on actions, see "Events". |
| Operation | Read-only list that lists operations of the classifier associated with the state that is the source of the transition. It allows you to specify the action implementation using an operation. It is grayed and empty when the classifier is not a class |
| Operation arguments | Arguments of an event defined on an operation |
