\qmltype PathLine \instantiates QQuickPathLine \inqmlmodule QtQuick

Defines a straight line.

The example below creates a path consisting of a straight line from 0,100 to 200,100:

\qml Path { startX: 0; startY: 100 PathLine { x: 200; y: 100 } } \endqml

See also: Path, PathQuad, PathCubic, PathArc, PathAngleArc, PathCurve, PathSvg, PathMove, PathPolyline

\qmlproperty real QtQuick::PathLine::x \qmlproperty real QtQuick::PathLine::y

Defines the end point of the line.

See also: relativeX, relativeY

\qmlproperty real QtQuick::PathLine::relativeX \qmlproperty real QtQuick::PathLine::relativeY

Defines the end point of the line relative to its start.

If both a relative and absolute end position are specified for a single axis, the relative position will be used.

Relative and absolute positions can be mixed, for example it is valid to set a relative x and an absolute y.

\qmltype PathCurve \instantiates QQuickPathCatmullRomCurve \inqmlmodule QtQuick

Defines a point on a Catmull-Rom curve.

PathCurve provides an easy way to specify a curve passing directly through a set of points. Typically multiple PathCurves are used in a series, as the following example demonstrates:

import QtQuick
 
Canvas {
    width: 400; height: 200
    contextType: "2d"
 
    Path {
        id: myPath
        startX: 0; startY: 100
 
        PathCurve { x: 75; y: 75 }
        PathCurve { x: 200; y: 150 }
        PathCurve { x: 325; y: 25 }
        PathCurve { x: 400; y: 100 }
    }
 
    onPaint: {
        context.strokeStyle = Qt.rgba(.4,.6,.8);
        context.path = myPath;
        context.stroke();
    }
}
