The drawing capabilities are + implemented by the subclasses TQWidget, TQPixmap, TQPicture and + TQPrinter. + + The default coordinate system of a paint device 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 device): + \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 device 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 retquires that a TQApplication object exists before + any paint devices can be created.
