PathCurve QML Type

  • Import Statement: import QtQuick

  • Group: PathCurve is part of qtquick-animation-paths

Detailed Description

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:

 
Sélectionnez
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):

Defines the end point of the curve.

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.
