State Toolbox

The State Toolbox is used to develop StateMachine diagrams, to show the enableable states a Class or other element might be in and the transitions from one state to another. These diagrams are often placed under a Class element in the Browser window to illustrate how a particular element changes over time. States can have substates; for example, Accelerate and Brake might be substates of Active.

Except where discussed here, each element and relationship that you can create using these Toolbox pages is described in the UML Elements and UML Connectors sections of the Help.

Event is used to create a basic Send element (the default) or Receive element on the StateMachine diagram.
