NAME

       QwtPolygonFData -

SYNOPSIS

       #include <qwt_data.h>

       Inherits QwtData.

Detailed Description
       Data class containing a single QwtArray<QwtDoublePoint> object.

Constructor &; Destructor Documentation
   QwtPolygonFData::QwtPolygonFData (const QPolygonF &polygon) Constructor
       Parameters:
	   polygon Polygon data

       See also:
	   QwtPlotCurve::setData()

Member Function Documentation
   QwtDoubleRect QwtData::boundingRect () const [virtual, inherited] Returns the bounding rectangle of the data. If there is no bounding rect,
       like for empty data the rectangle is invalid: QwtDoubleRect::isValid() == false
       Warning:
	   This is an slow implementation iterating over all points. It is intended to be overloaded by derived classes. In case of auto scaling
	   boundingRect() is called for every replot, so it might be worth to implement a cache, or use x(0), x(size() - 1) for ordered data ...

       Reimplemented in QwtArrayData, and QwtCPointerData.

   QwtData * QwtPolygonFData::copy () const [virtual] Returns:
	   Pointer to a copy (virtual copy constructor)

       Implements QwtData.

   const QPolygonF & QwtPolygonFData::data () const Returns:
	   Point array

   QwtPolygonFData & QwtPolygonFData::operator= (const QwtPolygonFData &data)
       Assignment.

   size_t QwtPolygonFData::size () const [virtual] Returns:
	   Size of the data set

       Implements QwtData.

   double QwtPolygonFData::x (size_ti) const [virtual] Return the x value of data point i
       Parameters:
	   i Index

       Returns:
	   x X value of data point i

       Implements QwtData.

   double QwtPolygonFData::y (size_ti) const [virtual] Return the y value of data point i
       Parameters:
	   i Index

       Returns:
	   y Y value of data point i

       Implements QwtData.
