\qmltype PathElement \instantiates QQuickPathElement \inqmlmodule QtQuick
PathElement is the base path type.
This type is the base for all path types. It cannot be instantiated.
\qmltype Path \instantiates QQuickPath \inqmlmodule QtQuick
Defines a path for use by \l PathView and \l Shape.
A Path is composed of one or more path segments - PathLine, PathPolyline, PathQuad, PathCubic, PathArc, PathAngleArc, PathCurve, PathSvg.
The spacing of the items along the Path can be adjusted via a PathPercent object.
PathAttribute allows named attributes with values to be defined along the path.
Path and the other types for specifying path elements are shared between \l PathView and \l Shape. The following table provides an overview of the applicability of the various path elements:

\qmlproperty bool QtQuick::Path::simplified
When set to true, the path will be simplified. This implies merging all subpaths that intersect, creating a path where there are no self-intersections. Consecutive parallel lines will also be merged. The simplified path is intended to be used with ShapePath.OddEvenFill. Bezier curves may be flattened to line segments due to numerical instability of doing bezier curve intersections.
