_create	Signature: 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.
_destroy	Signature: void _destroy Description: Explicitly destroys the object Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.
_destroyed?	Signature: [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.
_is_const_object?	Signature: [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.
_manage	Signature: void _manage Description: Marks the object as managed by the script side. After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24.
_unmanage	Signature: void _unmanage Description: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24.
colorCount	Signature: [const] int colorCount Description: Method int QPaintDevice::colorCount()
create	Signature: void create Description: Ensures the C++ object is created Use of this method is deprecated. Use _create instead 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.
depth	Signature: [const] int depth Description: Method int QPaintDevice::depth()
destroy	Signature: void destroy Description: Explicitly destroys the object Use of this method is deprecated. Use _destroy instead Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.
destroyed?	Signature: [const] bool destroyed? Description: Returns a value indicating whether the object was already destroyed Use of this method is deprecated. Use _destroyed? instead 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.

devicePixelRatioF	Signature: [const] double devicePixelRatioF Description: Method double QPaintDevice::devicePixelRatioF()
devicePixelRatioFScale	Signature: [static] double devicePixelRatioFScale Description: Static method double QPaintDevice::devicePixelRatioFScale() This method is static and can be called without an instance.
height	Signature: [const] int height Description: Method int QPaintDevice::height()
heightMM	Signature: [const] int heightMM Description: Method int QPaintDevice::heightMM()
initPainter	Signature: [const] void initPainter (QPainter ptr painter) Description: Virtual method void QPaintDevice::initPainter(QPainter *painter) This method can be reimplemented in a derived class.
is_const_object?	Signature: [const] bool is_const_object? Description: Returns a value indicating whether the reference is a const reference Use of this method is deprecated. Use _is_const_object? instead This method returns true, if self is a const reference. In that case, only const methods may be called on self.
logicalDpiX	Signature: [const] int logicalDpiX Description: Method int QPaintDevice::logicalDpiX()
logicalDpiY	Signature: [const] int logicalDpiY Description: Method int QPaintDevice::logicalDpiY()
metric	Signature: [const] int metric (const QPaintDevice_PaintDeviceMetric metric) Description: Virtual method int QPaintDevice::metric(QPaintDevice::PaintDeviceMetric metric) This method can be reimplemented in a derived class.
new	Signature: [static] new QPaintDevice new Description: Constructor QPaintDevice::QPaintDevice() This method creates an object of class QPaintDevice. Python specific notes: This method is the default initializer of the object.
paintEngine	Signature: [const] QPaintEngine ptr paintEngine Description: Virtual method QPaintEngine *QPaintDevice::paintEngine() This method can be reimplemented in a derived class.
paintingActive	Signature: [const] bool paintingActive Description: Method bool QPaintDevice::paintingActive()
physicalDpiX	Signature: [const] int physicalDpiX Description: Method int QPaintDevice::physicalDpiX()
physicalDpiY	Signature: [const] int physicalDpiY Description: Method int QPaintDevice::physicalDpiY()
redirected	Signature: [const] QPaintDevice ptr redirected (QPoint ptr offset) Description: Virtual method QPaintDevice QPaintDevice::redirected(QPoint offset) This method can be reimplemented in a derived class.
sharedPainter	Signature: [const] QPainter ptr sharedPainter Description: Virtual method QPainter *QPaintDevice::sharedPainter() This method can be reimplemented in a derived class.
width	Signature: [const] int width Description: Method int QPaintDevice::width()
widthMM	Signature: [const] int widthMM Description: Method int QPaintDevice::widthMM()
