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 requires that a TQApplication 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. */ // // Some global variables - these are initialized by TQColor::initialize() // Display *TQPaintDevice::x_appdisplay = 0; int TQPaintDevice::x_appscreen; int TQPaintDevice::x_appdepth; int TQPaintDevice::x_appcells; TQt::HANDLE TQPaintDevice::x_approotwindow; TQt::HANDLE TQPaintDevice::x_appcolormap; bool TQPaintDevice::x_appdefcolormap; void *TQPaintDevice::x_appvisual; bool TQPaintDevice::x_appdefvisual; // ### in 4.0, remove the above, and use the below int *TQPaintDevice::x_appdepth_arr; int *TQPaintDevice::x_appcells_arr; TQt::HANDLE *TQPaintDevice::x_approotwindow_arr; TQt::HANDLE *TQPaintDevice::x_appcolormap_arr; bool *TQPaintDevice::x_appdefcolormap_arr; void **TQPaintDevice::x_appvisual_arr; bool *TQPaintDevice::x_appdefvisual_arr; /*! \enum TQPaintDevice::PDevCmd \internal */ /*!
