Detailed description

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.

[const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

[static] new QGraphicsSceneHelpEvent new(const QEvent_Type type = QEvent::None)

Description: Constructor QGraphicsSceneHelpEvent::QGraphicsSceneHelpEvent(QEvent::Type type)

This method creates an object of class QGraphicsSceneHelpEvent.

[const] QPointF scenePos

Description: Method QPointF QGraphicsSceneHelpEvent::scenePos()

void scenePos=(const QPointF pos)

Description: Method void QGraphicsSceneHelpEvent::setScenePos(const QPointF &pos)

[const] QPoint screenPos

Description: Method QPoint QGraphicsSceneHelpEvent::screenPos()

void screenPos=(const QPoint pos)

Description: Method void QGraphicsSceneHelpEvent::setScreenPos(const QPoint &pos)

void setScenePos(const QPointF pos)

Description: Method void QGraphicsSceneHelpEvent::setScenePos(const QPointF &pos)

void setScreenPos(const QPoint pos)

Description: Method void QGraphicsSceneHelpEvent::setScreenPos(const QPoint &pos)
