void active=(bool newState)

Description: Method void QPaintEngine::setActive(bool newState)

[virtual] bool begin(QPaintDevice ptr pdev)

Description: Virtual method bool QPaintEngine::begin(QPaintDevice *pdev)

This method can be reimplemented in a derived class.

[virtual,const] QPoint coordinateOffset

Description: Virtual method QPoint QPaintEngine::coordinateOffset()

This method can be reimplemented in a derived class.

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.

[virtual] void drawEllipse(const QRectF r)

Description: Virtual method void QPaintEngine::drawEllipse(const QRectF &r)

This method can be reimplemented in a derived class.

[virtual] void drawEllipse(const QRect r)

Description: Virtual method void QPaintEngine::drawEllipse(const QRect &r)

This method can be reimplemented in a derived class.

Description: Virtual method void QPaintEngine::drawImage(const QRectF &r, const QImage &pm, const QRectF &sr, QFlags<Qt::ImageConversionFlag> flags)

This method can be reimplemented in a derived class.

[virtual] void drawPath(const QPainterPath path)

Description: Virtual method void QPaintEngine::drawPath(const QPainterPath &path)
