NAME

       QwtPointSeriesData -

       Interface for iterating over an array of points.

SYNOPSIS

       #include <qwt_series_data.h>

       Inherits QwtArraySeriesData< QPointF >.

   Public Member Functions
       QwtPointSeriesData (const QVector< QPointF > &=QVector< QPointF >())
       virtual QRectF boundingRect () const

Detailed Description
       Interface for iterating over an array of points.

Constructor &; Destructor Documentation
   QwtPointSeriesData::QwtPointSeriesData (const QVector< QPointF > &samples = QVector<QPointF>()) Constructor
       Parameters:
	   samples Samples

Member Function Documentation
   QRectF QwtPointSeriesData::boundingRect () const [virtual]
       Calculate the bounding rect. The bounding rectangle is calculated once by iterating over all points and is stored for all following
       requests.

       Returns:
	   Bounding rectangle

       Implements QwtSeriesData< QPointF >.

Detailed Description
       A null paint device doing nothing.

       Sometimes important layout/rendering geometries are not available or changable from the public Qt class interface. ( f.e hidden in the
       style implementation ).

       QwtNullPaintDevice can be used to manipulate or filter out these informations by analyzing the stream of paint primitives.

       F.e. QwtNullPaintDevice is used by QwtPlotCanvas to identify styled backgrounds with rounded corners.
