Detailed description

void addToIndex

Description: Method void QGraphicsPolygonItem::addToIndex()

This method is protected and can only be called from inside a derived class.

[virtual] void advance(int phase)

Description: Virtual method void QGraphicsPolygonItem::advance(int phase)

This method can be reimplemented in a derived class.

[virtual,const] QRectF boundingRect

Description: Virtual method QRectF QGraphicsPolygonItem::boundingRect()

void create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

void destroy

Description: Explicitly destroy the object

Explicitly destroy the object on C++ side if it was owned by the Ruby interpreter. Subsequent access to this object will throw an exception. If the object is not owned by Ruby, this method will do nothing.

[const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.
