NAME
       QCanvasSpline - Multi-bezier splines on a QCanvas

SYNOPSIS
       #include <qcanvas.h>

       Inherits QCanvasPolygon.

   Public Members
       QCanvasSpline ( QCanvas * canvas )
       ~QCanvasSpline ()
       void setControlPoints ( QPointArray ctrl, bool close = TRUE )
       QPointArray controlPoints () const
       bool closed () const
       virtual int rtti () const

DESCRIPTION
       The QCanvasSpline class provides multi-bezier splines on a QCanvas.

       A QCanvasSpline is a sequence of 4-point bezier curves joined together
       to make a curved shape.

       You set the control points of the spline with setControlPoints().

       If the bezier is closed(), then the first control point will be re-used
       as the last control point. Therefore, a closed bezier must have a
       multiple of 3 control points and an open bezier must have one extra
       point.

       The beziers are not necessarily joined "smoothly". To ensure this, set
       control points appropriately (general reference texts about beziers
       will explain this in detail).

       Like any other canvas item splines can be moved with
       QCanvasItem::move() and QCanvasItem::moveBy(), or by setting
       coordinates with QCanvasItem::setX(), QCanvasItem::setY() and
       QCanvasItem::setZ().

       See also Graphics Classes and Image Processing Classes.

MEMBER FUNCTION DOCUMENTATION
QCanvasSpline::QCanvasSpline ( QCanvas * canvas )
       Create a spline with no control points on the canvas canvas.

       See also setControlPoints().

QCanvasSpline::~QCanvasSpline ()
       Destroy the spline.

bool QCanvasSpline::closed () const
       Returns TRUE if the control points are a closed set; otherwise returns
       FALSE.

QPointArray QCanvasSpline::controlPoints () const
       Returns the current set of control points.

       See also setControlPoints() and closed().

int QCanvasSpline::rtti () const [virtual]
       Returns 8 (QCanvasItem::Rtti_Spline).

       See also QCanvasItem::rtti().

       Reimplemented from QCanvasPolygon.

void QCanvasSpline::setControlPoints ( QPointArray ctrl, bool close = TRUE )
       Set the spline control points to ctrl.

       If close is TRUE, then the first point in ctrl will be re-used as the
       last point, and the number of control points must be a multiple of 3.
       If close is FALSE, one additional control point is required, and the
       number of control points must be one of (4, 7, 10, 13, ...).

       If the number of control points doesn't meet the above conditions, the
       number of points will be truncated to the largest number of points that
       do meet the requirement.

       Example: canvas/canvas.cpp.
