Detailed Description
       A class for drawing symbols.

Member Enumeration Documentation
   enum QwtSymbol::Style Style
       See also:
	   setStyle(), style()

Constructor &; Destructor Documentation
   QwtSymbol::QwtSymbol () Default Constructor
       The symbol is constructed with gray interior, black outline with zero width, no size and style 'NoSymbol'.

   QwtSymbol::QwtSymbol (QwtSymbol::Stylestyle, const QBrush &brush, const QPen &pen, const QSize &size)
       Constructor. Parameters:
	   style Symbol Style
	   brush brush to fill the interior
	   pen outline pen
	   size size

   QwtSymbol::~QwtSymbol () [virtual]
       Destructor.

Member Function Documentation
   const QBrush& QwtSymbol::brush () const [inline]
       Return Brush.

   QwtSymbol * QwtSymbol::clone () const [virtual] Allocate and return a symbol with the same attributes
       Returns:
	   Cloned symbol

   void QwtSymbol::draw (QPainter *painter, const QRect &r) const [virtual]
       Draw the symbol into a bounding rectangle. This function assumes that the painter has been initialized with brush and pen before. This
       allows a much more performant implementation when painting many symbols with the same brush and pen like in curves.

       Parameters:
	   painter Painter
	   r Bounding rectangle

   void QwtSymbol::draw (QPainter *painter, const QPoint &pos) const
       Draw the symbol at a specified point. Parameters:
	   painter Painter
	   pos Center of the symbol

   void QwtSymbol::draw (QPainter *p, intx, inty) const
       Draw the symbol at a point (x,y).

   bool QwtSymbol::operator!= (const QwtSymbol &other) const
       != operator

   bool QwtSymbol::operator== (const QwtSymbol &other) const [virtual]
       == operator

   const QPen& QwtSymbol::pen () const [inline]
       Return Pen.

   void QwtSymbol::setBrush (const QBrush &brush)
       Assign a brush. The brush is used to draw the interior of the symbol.

       Parameters:
	   brush Brush

   void QwtSymbol::setPen (const QPen &pen) Assign a pen
       The pen is used to draw the symbol's outline.

       The width of non cosmetic pens is scaled according to the resolution of the paint device.

       Parameters:
	   pen Pen

       See also:
	   pen(), setBrush(), QwtPainter::scaledPen()

   void QwtSymbol::setSize (const QSize &size) Set the symbol's size
       Parameters:
	   size Size

   void QwtSymbol::setSize (intwidth, intheight = -1)
       Specify the symbol's size. If the 'h' parameter is left out or less than 0, and the 'w' parameter is greater than or equal to 0, the symbol
       size will be set to (w,w).

       Parameters:
	   width Width
	   height Height (defaults to -1)

   void QwtSymbol::setStyle (QwtSymbol::Styles)
       Specify the symbol style. The following styles are defined:

       NoSymbol
	   No Style. The symbol cannot be drawn.

       Ellipse
	   Ellipse or circle

       Rect
	   Rectangle

       Diamond
	   Diamond

       Triangle
	   Triangle pointing upwards

       DTriangle
	   Triangle pointing downwards

       UTriangle
	   Triangle pointing upwards

       LTriangle
	   Triangle pointing left

       RTriangle
	   Triangle pointing right

       Cross
	   Cross (+)

       XCross
	   Diagonal cross (X)

       HLine
	   Horizontal line

       VLine
	   Vertical line

       Star1
	   X combined with +

       Star2
	   Six-pointed star

       Hexagon
	   Hexagon

       Parameters:
	   s style

   const QSize& QwtSymbol::size () const [inline]
       Return Size.

   Style QwtSymbol::style () const [inline]
       Return Style.
