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 2.0 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(); } }
This example produces the following path (with the starting point and PathCurve points highlighted in red):

relativeX : real |
relativeY : real |
Defines the end point of the curve 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.
x : real |
y : real |
Defines the end point of the curve.
