详细描述

A Path is composed of one or more path segments - PathLine , PathQuad , PathCubic , PathArc , PathCurve , PathSvg .

The spacing of the items along the Path can be adjusted via a PathPercent 对象。

PathAttribute allows named attributes with values to be defined along the path.

closed : bool

This property holds whether the start and end of the path are identical.

[default] pathElements : list < PathElement >

This property holds the objects composing the path.

A path can contain the following path objects:

• PathLine - a straight line to a given position.
• PathQuad - a quadratic Bezier curve to a given position with a control point.
• PathCubic - a cubic Bezier curve to a given position with two control points.
• PathArc - an arc to a given position with a radius.
• PathSvg - a path specified as an SVG path data string.
• PathCurve - a point on a Catmull-Rom curve.
• PathAttribute - an attribute at a given position in the path.
• PathPercent - a way to spread out items along various segments of the path.

    PathView {
        anchors.fill: parent
        model: ContactModel {}
        delegate: delegate
        path: Path {
            startX: 120; startY: 100
            PathAttribute { name: "iconScale"; value: 1.0 }
            PathAttribute { name: "iconOpacity"; value: 1.0 }
            PathQuad { x: 120; y: 25; controlX: 260; controlY: 75 }
            PathAttribute { name: "iconScale"; value: 0.3 }
            PathAttribute { name: "iconOpacity"; value: 0.5 }
            PathQuad { x: 120; y: 100; controlX: -20; controlY: 75 }
        }
    }
							

startX : real

These properties hold the starting position of the path.

startY : real

These properties hold the starting position of the path.
