Possible to draw dashed line using 2d context in Canvas?



  • I've got a Canvas on my window and I'm drawing a line on it:

    @
    Canvas
    {
    onPaint:
    {
    var ctx = getContext("2d");
    ctx.reset();
    ctx.beginPath();
    ctx.strokeStyle = "green";
    ctx.moveTo(0, 0);
    ctx.lineTo(100, 100);
    ctx.stroke();
    }
    }
    @

    But I would like the line to be dashed, not solid. Is there any way to do this? I tried setting the stroke style to a pattern:

    @
    var pat = ctx.createPattern("green", Qt.CrossPattern);
    ctx.strokeStyle = pat;
    @

    but none of the available patterns result in a good-looking dashed line.

    Any suggestions?

    Thanks,
    Chris
