Its default coordinate system has + its origin located at the top-left position. X increases to the + right and Y increases downwards. The unit is one pixel. + + The drawing capabilities of QPaintDevice are currently implemented + by the QWidget, QImage, QPixmap, QGLPixelBuffer, QPicture, and + QPrinter subclasses. + + To implement support for a new backend, you must derive from + QPaintDevice and reimplement the virtual paintEngine() function to + tell QPainter which paint engine should be used to draw on this + particular device. Note that you also must create a corresponding + paint engine to be able to draw on the device, i.e derive from + QPaintEngine and reimplement its virtual functions. + + \warning Qt requires that a QApplication object exists before + any paint devices can be created. Paint devices access window + system resources, and these resources are not initialized before + an application object is created. + + The QPaintDevice class provides several functions returning the + various device metrics: The depth() function returns its bit depth + (number of bit planes). The height() function returns its height + in default coordinate system units (e.g. pixels for QPixmap and + QWidget) while heightMM() returns the height of the device in + millimeters. Similiarily, the width() and widthMM() functions + return the width of the device in default coordinate system units + and in millimeters, respectively. Alternatively, the protected + metric() function can be used to retrieve the metric information + by specifying the desired PaintDeviceMetric as argument. + + The logicalDpiX() and logicalDpiY() functions return the + horizontal and vertical resolution of the device in dots per + inch. The physicalDpiX() and physicalDpiY() functions also return + the resolution of the device in dots per inch, but note that if + the logical and vertical resolution differ, the corresponding + QPaintEngine must handle the mapping. Finally, the numColors() + function returns the number of different colors available for the + paint device. + + \sa QPaintEngine, QPainter, {The Coordinate System}, {The Paint + System} +*/ + +/*! + \enum QPaintDevice::PaintDeviceMetric + + Describes the various metrics of a paint device. + + \value PdmWidth The width of the paint device in default + coordinate system units (e.g. pixels for QPixmap and QWidget).
