- \brief The TDEQt4PaintDevice class is a paint device that records and
- replays TQPainter commands.
+ \class TDEQt4PaintDevice tdeqt4painter.h
+ \brief The TDEQt4PaintDevice class is a paint device that translates
+ Qt paint events to a TQt painter.

\ingroup shared
- A picture serializes painter commands to an IO device in a
- platform-independent format. For example, a picture created under
- Windows can be read on a Sun SPARC.
-
- Pictures are called meta-files on some platforms.
-
- TQt pictures use a proprietary binary format. Unlike native picture
- (meta-file) formats on many window systems, TQt pictures have no
- limitations regarding their contents. Everything that can be
- painted can also be stored in a picture, e.g. fonts, pixmaps,
- regions, transformed graphics, etc.
-
- TDEQt4PaintDevice is an \link shclass.html implicitly shared\endlink class.
-
- Example of how to record a picture:
- \code
- TDEQt4PaintDevice pic;
- TQPainter p;
- p.begin( &pic ); // paint in picture
- p.drawEllipse( 10,20, 80,70 ); // draw an ellipse
- p.end(); // painting done
- pic.save( "drawing.pic" ); // save picture
- \endcode
-
- Example of how to replay a picture:
- \code
- TDEQt4PaintDevice pic;
- pic.load( "drawing.pic" ); // load picture
- TQPainter p;
- p.begin( &myWidget ); // paint in myWidget
- p.drawPicture( pic ); // draw the picture
- p.end(); // painting done
- \endcode
-
- Pictures can also be drawn using play(). Some basic data about a
- picture is available, for example, size(), isNull() and
- boundingRect().
