/**

|
* This class is the graphical version of a UML State.
|
|
*
|
|
* A StateWidget is created by a @ref UMLView. A StateWidget belongs to
|
|
* only one @ref UMLView instance.
|
|
* When the @ref UMLView instance that this class belongs to is destroyed,
|
|
* it will be automatically deleted.
|
|
*
|
|
* The StateWidget class inherits from the @ref UMLWidget class which adds
|
|
* most of the functionality to this class.
