- \class TQPaintDevice tqpaintdevice.h - \brief The TQPaintDevice class is the base class of objects that - can be painted. - - \ingroup graphics - \ingroup images - - A paint tqdevice is an abstraction of a two-dimensional space that - can be drawn using a TQPainter. The drawing capabilities are - implemented by the subclasses TQWidget, TQPixmap, TQPicture and - TQPrinter. - - The default coordinate system of a paint tqdevice has its origin - located at the top-left position. X increases to the right and Y - increases downward. The unit is one pixel. There are several ways - to set up a user-defined coordinate system using the painter, for - example, using TQPainter::setWorldMatrix(). - - Example (draw on a paint tqdevice): - \code - void MyWidget::paintEvent( TQPaintEvent * ) - { - TQPainter p; // our painter - p.begin( this ); // start painting the widget - p.setPen( red ); // red outline - p.setBrush( yellow ); // yellow fill - p.drawEllipse( 10, 20, 100,100 ); // 100x100 ellipse at position (10, 20) - p.end(); // painting done - } - \endcode - - The bit block transfer is an extremely useful operation for - copying pixels from one paint tqdevice to another (or to itself). It - is implemented as the global function bitBlt(). - - Example (scroll widget contents 10 pixels to the right): - \code - bitBlt( myWidget, 10, 0, myWidget ); - \endcode - - \warning TQt requires that a TQApplication object exists before - any paint tqdevices can be created.
