Toolbar items

This section describes the tools provided in order to build a State Diagram. For further information please refer to the UML specification available on the OMG web site.

Initial state

An initial state item represents the first active state within a diagram.

Final state 

A final state item represents the end of the active state


State items indicate the states of the elements modelized by the diagram.

History state

This tool creates a history item which is used to access the previous state of a state item.
A history state item can only be created into a state item.


A join/fork item is used to synchronize (ie join) or fork transitions.


Transitions represent a change in state of the elements modelized by the diagram.
