+.SH DESCRIPTION
+The QCanvasSpline class provides multi-bezier splines on a QCanvas.
+.PP
+A QCanvasSpline is a sequence of 4-point bezier curves joined together to make a curved shape.
+.PP
+You set the control points of the spline with setControlPoints().
+.PP
+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.
+.PP
+The beziers are not necessarily joined "smoothly". To ensure this, set control points appropriately (general reference texts about beziers will explain this in detail).
+.PP
+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().
+.PP
+See also Graphics Classes and Image Processing Classes.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QCanvasSpline::QCanvasSpline ( QCanvas * canvas )"
+Create a spline with no control points on the canvas \fIcanvas\fR.
+.PP
+See also setControlPoints().
+.SH "QCanvasSpline::~QCanvasSpline ()"
+Destroy the spline.
+.SH "bool QCanvasSpline::closed () const"
+Returns TRUE if the control points are a closed set; otherwise returns FALSE.
+.SH "QPointArray QCanvasSpline::controlPoints () const"
+Returns the current set of control points.
+.PP
+See also setControlPoints() and closed().
+.SH "int QCanvasSpline::rtti () const\fC [virtual]\fR"
+Returns 8 (QCanvasItem::Rtti_Spline).
+.PP
+See also QCanvasItem::rtti().
+.PP
+Reimplemented from QCanvasPolygon.
+.SH "void QCanvasSpline::setControlPoints ( QPointArray ctrl, bool close = TRUE )"
+Set the spline control points to \fIctrl\fR.
+.PP
+If \fIclose\fR is TRUE, then the first point in \fIctrl\fR will be re-used as the last point, and the number of control points must be a multiple of 3. If \fIclose\fR is FALSE, one additional control point is required, and the number of control points must be one of (4, 7, 10, 13, ...).
+.PP
+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.
+.PP
+Example: canvas/canvas.cpp.
