In this sample:
Canvas {
id: canvas
anchors.fill: parent
property real endAngle: 0
onEndAngleChanged: canvas.requestPaint()
onPaint: {
var ctx = getContext("2d");
ctx.reset();
ctx.lineWidth = 10;
ctx.strokeStyle = "red"
ctx.beginPath();
ctx.arc(width / 2, height / 2, 50, 0.0, canvas.endAngle, true);
ctx.stroke();
}
}
NumberAnimation { id: anim; target: canvas; property: "endAngle"; to: Math.PI / 2; duration: 5000 }
Component.onCompleted: anim.start()
with the anticlockwise direction and with the "0 < angle < PI (180 degree)", the arc has a wrong form (see "bug-draw-direction" screenshoot).
Besides, the animation shows that grawing starts from the whole arc as 0-360 degre.. with the wrong clockwise direction!
